As a locally owned and operated Radon Mitigation and Electrical Services company, the reviews we receive from our customers are very important to us. We are proud to say that nearly every review we have ever received has been 5 stars. But you don’t have to take our word for it, read some of those reviews below and check us out on all the popular online review sites. We think you’ll be impressed!
The motor in my radon detection system was making the “I’ve got a bad bearing” sound. I called the Guardian since they were on a label on the detector as the installer over 7 years ago. They were out the next day and professionally installed a new motor at a very reasonable price. Highly recommend.
Guardian did an excellent job from the initial proposal from Mike, to the follow-up from Mary Ann, to the communication from Chris, to the actual work performed. Both Mike and Matt did a great job installing the mitigation system from start to finish. They were very clean and the piping/gutter/fan on the outside blends right in. Lastly, our radon levels went from an average of 9.0 before mitigation to an average of 0.4 after the mitigation system was installed (two days later). A big Thank you to Guardian’s entire team!
Fantastic all around from responsiveness, quick and clear quote, and expert installation. It was a major plus to have a color-matched downspout option instead of just a plain white PVC pipe on the exterior. Also, they installed a whole home surge protector for a very reasonable price. We couldn’t be happier.
I was incredibly impressed with all levels of service from Guardian Radon. I reached out to them after hearing noises coming from my radon fan and they were able to come out within the week to inspect it and ultimately replace the fan. Tyler was extremely knowledgeable about the system and answered all of my questions and he and Caleb were pleasant and service was quick and efficient. We did encounter an issue due to the fact the incorrect roof boot was installed by the roofing company, and Tyler provided me all the information needed to pass along to make sure it was fixed to code. They were then able to come out the next week to finish the installation. Wanted to give a shout out too to Mary Ann in the front office for being so lovely and flexible with my schedule. Highly recommend Guardian Radon!
Guardian did a great job, they took the time to explain everything up front and provided an easy to understand estimate. The work was completed during the scheduled time period for the amount stated in the estimate. The technicians were friendly and left the work site spotless. I would definitely recommend them.
We had a great experience with Guardian. They were professional, punctual, and answered all my questions. I asked them to activate my passive radon reduction system and Chris and Mary Anne were great about setting expectations and giving us the right info upfront. Tyler and Caleb did a great job with the install. We are extremely happy with the new system and the radon readings are now significantly reduced.
The people at this company were professional and very knowledgeable. We had a tight window to have services done and they made it happen without charging us an arm and a leg!
Mike Christerson (Eastern Area Technician) of Guardian Radon Mitigation along with Mary Anne Bice Business Manager), Matt, and Eric set up time to put a fan in our attic to make sure our radon stays lower than 1. Their system was FIRST CLASS and they were in and out within 2 to 3 hours. We highly recommend them!

Chris & the team we great. The process was thoroughly explained and was quickly scheduled. Guardian Radon Mitigation has definitely earned my recommendation.
This company was top-notch to deal with from the first information gathering call with Mary Ann, to the pre-inspection with Chris, to the installation and follow-up after!!! Installers were professional, courteous and explained everything with obvious knowledge and thoroughness. I would recommend this company for anyone needing radon mitigation!
Last week I had Guardian install a Radon Mitigation system at my personal home. They are a local small business that I have supported for years. I’ve always enjoyed my interaction with them and their professionalism. My clients have never been disappointed. They set proper expectations, communicated well, did a high quality install, left no mess, and were reasonably priced. I love being able to refer contractors that have done work for me personally. Keep up the great work guys!
Called in the AM Monday as the motor on the radon abatement devise was load. Was told she’d call back for a date and time as I’d given my availability. Received a call with 5 minutes that they could be here today at noon. Guys came. Smart and professional. Replaced the motor and corrected a dent at the top of the tube on the roof that had been hit by something. System fixed. Thank you Guardian! Appreciate the quick, professional and accurate repair.
From my initial phone call, the woman that answered the phone was incredibly knowledgeable and thoroughly explained the process. Mike and his team provided exceptional service, I was able to work from home and not miss a beat. They were extremely efficient and professional. Literally a breathe of fresh clean air. Readings near our sump in the basement went from roughly 13 pCi/L to 0.2 pCi/L. whereas our living area went from 3 pCi/L to ZERO. 1000% recommend this company.
WOWWWW, from start to finish Guardian is the way to go for radon mitigation! Not knowing much about what Radon was, every person involved in our install was super knowledgeable in explaining what needed to happen to eliminate as much radon in our home as possible. Thank you to the install team for making it seamless, thank you to the in home consultation & planning our install, and thank you to the receptionist taking our call and answering our initial questions! Guardian is the best in town!
Every encounter with the employees of this company has been great. We recently purchased a home that had very high levels of radon, when I called them to get a quote Mary Anne was extremely helpful and informative. We have a gravel crawl space and she explained the whole process including the type of material they used as well as the sealing products. Then when they came out to give the estimate it was very quick and Chris was very informative as well. The day of installation they arrived at 7 am on the dot and were actually quicker than they originally told me. Once they were done the guys that installed the mitigation system they showed me everything they did, how to read the monitor and what issues would sound/look like. There was open communication the entire time and overall I was very happy with their services. I would recommend them to anyone in the area!
The Guardian Radon team is very professional and experts in mitigating hazardous radon levels. I now have a healthy home!
On time
Very professional
Excellent business
Thanks for the personal service
Just had our Radon Mitigation System installed and Guardian tech’s were AWESOM! The installation was completed in a very efficient manner and met high quality standards. The technicians were very informative and shared all key information and operational details. any disruption was maintained at a minimum and cleanup was excellent. My wife and I are very pleased with the entire job and would recommend Guardian to any/all new clients.
Very Happy Customers
T&T
During the process of selling our home, we were surprised to receive notice on the radon testing that we would have to mitigate. Our realtor suggested Guardian, and our experience with them was one we’d highly recommend. We’ve had such bad luck with sloppy contractors over the years, but Guardian’s attention to detail is unmatched. They left my home as clean, if not cleaner, than when they arrived, and the mitigation system blends perfectly into the interior and exterior. They arrived on time, early this morning, and were completely finished before 10am. While we weren’t thrilled to have to spend the money, we’re glad we were able to work with Guardian to get what needed to be completed done.
Radon was not on my radar until we tested our levels and saw that they were about 4x over the recommended safe levels (!). After doing a Yelp search, I came across Guardian. From beginning to end, this company was a pleasure to work with, was consultative and, most importantly, fixed our radon issue. Mary Anne patiently and thoroughly answered all of the questions I had and got us scheduled for an in-person quote. Chris showed up promptly at the agreed time of quote, wearing a mask, and again was extremely thorough in explaining how a radon mitigation system works, what to expect on install day and the cost of the job (very fair in our opinion). Everything sounded good and we agreed to have the work done. Mary Anne scheduled us, Chris was on site with the installers on the day the work was done, and everything went according to what was explained in the quote. Everyone wore masks inside on install day the entire time, without being asked to do so. This was a nice and welcome touch of professionalism during a pandemic. The radon mitigation system is very neatly and unobtrusively placed. Both interior and exterior appearance is very tidy and streamlined. Most importantly, our radon levels are now consistently in the HEALTHY range, tracked daily by my Corentium radon detector. If you have radon and need to get it mitigated, go with Guardian.
Professional, friendly, and very helpful. Every member of the team I interacted with was extremely helpful and quick to respond whenever I had a question or concerns. Highly recommend Guardian for any applicable services.
Guardian recently installed a system that dramatically reduced the radon levels in my home. There was excellent communication with them before, during, and after the job, the finished product looks professional and works well, and I especially appreciated that they accommodated my input for how to route the plumbing as unobtrusively as possible. Recommended!
Working with Guardian has been one of the very best experiences we had while selling our home. No one wants to learn that they have an elevated radon issue, but after the buyer’s radon tester discovered it, we immediately reached out to Guardian for mitigation and we are so happy we did. Mary Anne and Chris are both extremely professional and friendly! The work was done quickly, cleanly, and right on schedule. The post-mitigation test showed excellent results! We could not be happier. I would definitely recommend them to anyone who needs help with radon mitigation. I’d give them 10 stars if I could! Thanks, Guardian!
The team at Guardian is so knowledgeable and helpful. They came out for the estimate and gave us an idea of where the equipment would go and how it would look. When they came out for the actual installation, my husband asked them if there was a way to have less of the equipment on the outside of the house and, on the spot, they came up with a much better solution. Highly recommend!
We highly recommend Guardian Radon. Chris & his team were very professional, informative, courtesy, neat & very fair with their pricing. They did a excellent job & we highly recommend them for your mitigation needs!
Radon levels in our home were very high. My husband did a quick search on google and found Guardian. Mary Anne was able to explain the process of radon mitigation to my husband and made herself available to answer additional questions. Chris came to the house to make an assessment and the price was within the estimate Mary Anne had previously mentioned to us over the phone. If you are looking for a Radon Mitigation company, search no more, you have found the right one. They are very thorough and kind professionals.
As a Home inspector and someone that has been in the construction industry for 40+ years it is easy to spot a contractor who does quality work for a reasonable cost. In my own home I have Guardian Radon install a vapor barrier in my crawl space to mitigate moisture issues I was having in the home. Both Matt and Mike were professional, they completed the project in the amount of time quoted and the work was completed in a professional manner, they cleaned up after them selves and they used high quality products in the completion of the task. I would highly recommend Guardian Radon and the work of both Mike and Matt.
What an amazing company! Everything about them was a pleasant interaction. They were prompt, professional and clean. All staff that comes on site is very respectful of your property and Mary Ann is quite knowledgeable while you are booking your appointment. Chris the owner, explains the entire system and also answered some other non-radon questions for me…super nice guy. I would not waste time calling any other company!
“Mike and Guardian are first-rate radon mitigation experts. Mine installed yesterday and looks/works fantastic.”
I would not hesitate to recommend this company to address your radon needs. They were great to work with and did a fantastic job with super radon retest results.
Mary Anne communicates all of the details very clearly and in a timely manner via phone & email. She was very knowledgeable and convinced me that they could do the job with quality. All paperwork & documentation was provided immediately once available to myself, my attorney & my realtor.
Thanks to Guardian Radon Mitigation!!! You Rock!!!
I found Guardian in my search for a company to troubleshoot my existing Radon System quickly. My home that was under contract failed a radon test during inspection. When I called, I was helped by Mary Anne who went above and beyond in customer service from beginning to end. Not only did she schedule me in within a couple of days but she also assisted in having my home retested. Mike came out to my home on time as scheduled. Within 5 minutes he knew the issue with my system. Since he had the parts needed in his truck, he was able to repair my system on the same visit. I will only recommend Guardian for any radon mitigation.
Professionalism, efficiency, and courtesy are the words I would use to describe Guardian Radon Mitigation & Electrical Services. We contacted them to install a radon mitigation system, and right away they took the time to explain the whole process clearly and answer all of our questions. The day of the installation was efficacy at its best. After the installation, you couldn’t tell they had been here, since they were extremely clean. It was obvious too that they enjoy the work they do. The best part, my radon level is down to 0.3! I enthusiastically recommend them to anyone looking for radon mitigation.
This is a company that can take great pride in customer service.Mike came out and gave an estimate and was willing to answer any question that I might have.Mary Ann was very friendly and made this a very smooth process. They left the basement very clean where they did the work, nothing left to clean up after they left.I will definitely recommend this family run company to all my friends and family. I will also use them again for any other properties that we may have to use a Radon Mitigation System. Thank you again for GREAT SERVICE!!
Called these guys after I read some reviews on Yelp. They responded quickly and were able to service our old broken radon fan the next day. They were very polite, wore masks, and followed social distancing protocols. The guys explained the work after diagnosing the problem. I felt their price was fair.
From my first phone call to my mitigation system installation, I had a phenomenal experience with Guardian. The cost of parts and labor was competitively priced when calling around for quotes/info. What really set Guardian apart was the level of customer service. When every other place had first appointments in mid July ( calling in early June ), Guardian made it out to me in 2 days. Additionally, Mary Anne ( phone ) provided me with knowledge and comfort when I first called. Chris ( tech/owner/expert ) came out to do my initial inspection and go over details of mitigation. To have the company owner hands on and involved made me feel even more connected and comfortable. On installation day, the team was on time, polite, professional, clean, and an overall pleasure to have in my home. I am happy to provide a 5 star review and recommend the services of Guardian to anyone and everyone.
Mike was super helpful for both the electrical work and the radon installation work we had done at our home. He explains things slowly and specifically, making it easy to understand, especially for first-time homeowners. He and the staff at Guardian either answer your call or text right away, or get back to you within a few hours. We’ll definitely go back to them for future needs!
Very happy with this company. Mike educated me on radon and what I needed to do to make my home safer for my family. Matt was the installer and he is a true professional. Mike helped with the installation as well. They both did a phenomenal job. I would recommend this company to those in need of radon mitigation.
My search for a radon mitigation company started after I purchased an AirThings electronic radon monitor from Amazon. I was shocked to learn that my radon levels were over 17 pCi/L in the basement and over 5 pCi/L on the 2nd floor! Several times the safe limit of 4pCi/L. Upon further research, I learned that these levels were equivalent to our entire family smoking a pack of cigarettes every day! Then I hired Guardian to mitigate the problem and make the air in our home safe again. I was really pleased with the work that Chris and his team did on-site. All of the work was clean and showed a great attention to detail. Cuts were straight, pipe runs were clean and they left their work areas spotless. The downspout used for venting was color-matched to the other downspouts which makes such a difference in the appearance of the system. Chris’s team was extremely courteous and finished their work very quickly in about 3 hours. The explanation of how the system works was very thorough. The price I was quoted after the walk-thru is the price I paid when the work was done. It was a small price to pay considering the long-term health effects of radon exposure. Working with Mary Anne on the phone in advance was very helpful to understand what to expect for the install and from the system itself. I would highly recommend Guardian and will do so to any of my neighbors.
Were very quick to get system installed before we sold our house. Very friendly and kept house clean. Highly recommend
Chris and Mary Anne were outstanding. Very professional from the moment I called. Chris came over to give me a free estimate on services that I needed and spent as much time as needed answering all my questions and concerns. If you are in need of a radon mitigation system, don’t waste your time calling anyone else, call Guardian, you won’t be disappointed.
We recently had a radon test done, and found out we needed a mitigation system. After a little search time, and a recommendation from the testing company, we settled on Guardian. What a great experience we had, the owner Chris was a real professional. He took the time to walk us through the steps we’d need to take, and the cost/timing. He was able to show us what the system would like from the outside of the house before it was installed. The whole process was very smooth, and we are very happy with the system. I highly recommend Guardian and the work they do.
I just wanted to take a moment to let you know that Mike Christerson and his team did a fantastic job designing and installing a Radon mitigation system in our home in Warrenville recently.
The original house is 75 years old and had several additions over the years. The original house was built on a crawl space and additions on slabs. Mike created an innovative design since the property was very challenging and unique.The installation was successful and the mitigation passed state requirements easily.It was a pleasure working with your company and would strongly recommend your services.
My wife and I were in need of a radon mitigation firm to take care of our higher than allowed reading that came back on our house. The first company we contacted was Guardian and Maryanne in the office who took our call was very pleasant and knowledgeable filling us in with information for us to get started by setting up a appointment for Chris to come out and survey the house, give us an estimate, what work will be performed and any issues that might arise. When Chris came out he was very knowledgeable explained other issues having to do with radon and its impacts. We had contacted another mitigation company they wanted to know square footage of house, full basement or crawl giving a price without even looking at the house. Yes it was a bit cheaper but I was impressed with Guardian and their professionalism before the work even started. When the day came to start the job his two workers arrived just shortly before Chris. The two workers very professional showed them the basement and exterior where they described where the work was to start. Chris arrived took over and they answered any questions I had a d explained things during the performed work. They seemed to have finished in the time Chris described. Everything looked great when they finished and picked up, you couldn’t tell they were there except for the system they installed. Very happy and satisfied, Thanks Chris and Guardian.
Mike and Matt did a great job installing my mitigation system. From the first time he came out to inspect my house, I knew Guardian was the right firm for me. They delivered what they said they would, made sure the system blended seamlessly into the look of my house, and were attentive to every detail in making sure there was minimum disruption and dirt. I love a contractor who delivers with integrity and that’s what Guardian did for us. I’m a big fan!
We are selling our 17 year old home with a passive Radon mitigation system. Maryanne was so knowledgeable, explaining Guardian’s service and setting our appointment with Chris to install a fan in our attic. After the installation our pCi/L reading in the basement was 10.2. We had Tyler and Caleb do a recore, and got the reading down to 5.0. . After doing a recore in our concrete crawl space, and a retest, we are now down to 0.6.
Guardian could not be more professional, knowledgeable and helpful in preparing our home for a successful sale and closing. We will recommend Guardian at every opportunity, and will use them in our new home, if needed.
Awesome company! Mary Ann, Chris and Mike were able to answer all of my questions which truly showed they are all professionals and are looking out for their customers. Mike and his team made sure that the system was installed efficiently, properly and as inconspicuous as possible. Bottom line, glad I did some homework and went with Guardian.
Great company. Fast, great pricing and great customer service. Would recommend this to anyone looking for radon mitigation
On a high from selling my house, i was soon brought down when house failed radon test. Decided to call Guardian best decision I made. They have great service, from Mary dealing with me on the phone and walking me thru the whole process making sure I understand completely each step. Being prompt with all emails and follow ups. To Chris and the the install crew also being prompt and on TIME for install and putting pride in there work. In the words of my instructor at IBEW, looks like it was born there. Passed retest 0.3! I would highly recommend Guardian to anyone needing radon mitigation!!!
I had a Radon mitigation system installed by this company and I’m very pleased with everything. Maryanne in the office is just wonderful to work with, very professional. Chris the owner did the installation along with two other gentleman.
Chris took the time to explain exactly what the system does and how they install it. They also sealed any cracks where the basement walls and floor met.
The work is top notch. They were in and out in about three hours.
I highly recommend these good people.
Working with Guardian has honestly been one of the best contractor experiences I’ve ever had. From our original install when we bought our house through storm damage, freezing temps and beyond, they are always ready to help. Absolutely worth the investment and I would definitely recommend them for any radon mitigation needs that you may have.
Guardian was great from start to finish. Mary Anne was super helpful explaining things and handling setup. Chris spent the necessary time to come up with the best solution for our house. Then Chris, Tyler and Caleb did a tremendous job installing the system while making it look as good inside and out as was possible. They were friendly and more than willing to take the time to explain what was done. If you need radon mitigation, call Guardian first!
Mike was thorough, courteous, and professional. The prices were much better than competitors and the system Guardian installed perfectly blended with the trim on our house. They’re also licensed electricians. Highly recommended.
Fantastic company, professional employees, quick service and great product with reliable results. Thanks for helping keep my family safe and for everything you provided, Guardian!
Great people doing God’s work helping folks avoid lung cancer. They were always on time and kept a clean work area.
Equipment was installed with function and appearance in mind.
They proudly put their name on the finished product and even refused to take a tip.
From start to finish they were 5 ⭐️! The lady who 1st took my phone call to book the appointment was super professional, helpful, and polite. And Chris and his crew was clean, quick, and knowledgeable! Anyone who needs Radon Mitigation must go with them to get it done CORRECTLY! Our results were under a 1 when we first had a 7 before the mitigation. No worries what so ever! #HappyCustomer
Excellent customer service from all team members I’ve interacted with. Mary Anne was excellent explaining, scheduling, and following up. Chris was super nice and informative from when he first came out for an estimate and even stopped by during the install. Tyler and his partner were great as well for the install of the fan and sealing of cracks. All were very informative and great people to work with! Thank you very much, Guardian!
Mary Anne and Chris are outstanding to work with. They’re great about communicating, quick turnarounds, and excellent service. No one dreams of putting a radon mitigation system in their home, but they make it a smooth process and the work is excellent. Everything is explained thoroughly. I would highly recommend Guardian to anyone needing radon mitigation done.

The team at Guardian were professional, knowledgeable and courteous. They answered all my questions and completed the project without any issues. I highly recommend Guardian Radon. Everyone should check for Radon to make sure your home is safe!
As new homeowners, we were extremely nervous after finding that the radon levels exceeded the acceptable level. After doing some research we found Guardian. They had awesome customer service and competitive pricing. The team was super responsive and did an excellent and clean job installing the mitigation system. Mike and Matt were very professional, with Mike going above and beyond what I had expected. Would HIGHLY recommend.
Great company. I send an email requesting info. Mary Ann was quick and very nice over the phone answering all my questions. Chris came a few days later gave us an estimate and explained how everything would work. Installation day went quick and smooth. Highly recommend them!
Jim Richards recommends Guardian Radon Mitigation & Electrical Services: “If anyone out there is looking for radon mitigation, these are the people to call! Quick, professional and easy to work with. They were in and out in a few hours with zero mess and their install was clean – you don’t even notice it is there! And the best part? Just had my post mitigation test – went from a 7.6 to a 0.6!!! (under 1.0 is hard to do)”
12/30/2019
I had to have a radon mitigation system installed resulting from a test to sell our home. A trusted service supplier recommended Guardian and I could not be more pleased. They arrived early as they said they would and completed the job in the time estimated. They explained exactly what they would do and why. I asked them to install an electrical switch while here and make another minor unrelated repair. They were happy to oblige. They left the work area neat and clean and before leaving informed my on how to tell the system is working and how often it should be checked. Good people; good work.
This company was immediately responsive, informative and professional, yet also very personable. MaryAnn explained all of the potential options, made recommendations, then reserved final decision making until they were on site. Chris and his team were super thorough about fixing the issue, but were all about making the home safe, not trying to upsell unnecessary services or products – just the kind of business we like to associate with as we share those same values. Highly recommend!
Selling a house can be stressful time and finding out that you need Radon mitigation made it even more worrisome. Our realtor recommended Guardian and we were very pleased with their services. They were prompt with their response to a request for a quote, a service date and arrival times. Most importantly retest results were fantastic with the added benefit of sharing those results with our real estate team! We highly recommend their services!
We are very pleased With the installation of our radon mitigation system. The Professionalism and detailed explanation of the system was very helpful. We especially liked the friendliness and understanding of what we needed from our initial phone call to the installation was so comforting. Thank you and WE STRONGLY RECOMMEND GUARDIAN AND THE WONDERFUL PEOPLE THAT WORK THERE. 100%
Guardian as a company has overall awesome people. Mary Ann coordinated everything when I called for the quotes. Chris, Caleb and Tyler were awesome and explained the whole process. They did a walk through after the whole installation and made sure I was satisfied with the installation. Totally recommend Guardian for your radon mitigation.
Great experience! These guys are extremely professional and efficient. The system is not totally ugly like others I’ve seen. Pricing is reasonable too.
Very professional team from the very first phone call to them leaving my home. Mary Anne calmed my nerves when speaking on the phone. She wasnt just trying to sell, you could tell she genuinely cared. Chris, the owner, came out the following business day and gave me a quote and we had the mitigation scheduled for that Friday. Greg, Tyler and Chris came and put the radon system in within 2.5 hours. I would highly recommend Guardian to anyone.
Chris & his crew are amazing. It was such a pleasant experience, all so knowledgeable, professional & very personable. Did an excellent job and very well priced & cleaned up as if they were never here. I also enjoyed talking to Mary Ann, this is a family owned business that treats you like family. I would recommend without reservations.
As a new home owner dealing with things like my “Radon Mitigation System” is a little overwhelming because of the very little knowledge I have about it. I will say Guardian was nothing shy of amazing to work with. MaryAnne was in constant contact with me and very informative about the entire process. I’m very pleased with my experience with them. If I could add another star I would!
This could not have gone any smoother! I loved working with Guardian! The staff is friendly, knowledgeable, and very skilled at what they do! They were able to install our mitigation system THE DAY after our consultation. I am so grateful to them. We had an amazing experience and cannot say enough good things about them! We highly recommend Guardian to install your radon mitigation system.
In the process of selling my home, an elevated radon level was detected. I called around to find the quickest and most efficient way to get the problem resolved and Guardian fit the bill. They came out to my home to check it out before quoting, then got me a quote quickly. We scheduled the service and the system was installed within a week. They handled the necessary village permits and scheduling the re-test, making it easy for me. I checked out the work after it was complete and I was impressed with how everything looked. Very well done and professional. I wouldn’t have known it was a new add-on if I hadn’t known it wasn’t there prior. Highly recommended!
What a great experience. Customer service was amazing. So prompt, kind, and got everything rolling. Installers were respectful, knowledgeable, and did a great job explaining everything about the system. Highly recommend!
Exceptional service is an understatement. These guys communicate well, go above and beyond to provide education, are punctual, and respectful of your property. Highly recommend!
Guardian Radon Mitigation is a first-rate company, with first-rate and HONEST service. They handled my issue within one day of contacting them, came out on time, checked my entire system, and were able to give me a clean bill of health without stalling, without equivocation, and without trying to sell me any upgrades. They are prompt, diligent, patient and most of all PROFESSIONAL. Call them. You will not be disappointed at all. In fact, you will be very, VERY pleased that you called them.
Chris, Mary Anne and their team are very cordial, efficient and skilled at their craft.
Chris and Mary Anne both took a lot of time to explain the theory of Radon mitigation and possible scenarios which really impressed me. It made it very easy to select a Radon mitigation company.In addition to the radon mitigation system, Chris tested our existing GFIC’s and installed an additional GFIC as requested by the buyers of our home.
The team installed my system neatly and efficiently with absolutely no mess to clean up.
We are very pleased with the whole experience and highly recommend the company.
Mike and Matt from Guardian Mitigation did a great job installing our Radon mitigation system. The install was clean and professional with the smallest foot print inside and out. They paid special attention to sealing any concrete floor cracks, sump pump well covers and where the floor meets the walls. It tested out well below gov norms! Thanks, great job guys!
We had this company out to repair our 23 yr old system. The were punctual and wearing face masks. They explained everything that needed to be done outside of what we thought was wrong. The best part was they had everything they needed already on the truck. I appreciate companies that are prepared for repairs that may not have been in the scope of the project. I would highly recommend this very professional company.
Higher than average radon levels in your home is never good. With all the radon mitigation companies out there, it can be very challenging knowing who to choose. I don’t normally write reviews, but I’m hoping this review helps you with your decision about choosing the best company for radon mitigation. I had a few estimates for radon mitigation and was very pleased that I hired Guardian for the job. Pricing is fair and the team is helpful and friendly. It was a very positive experience from start to finish.
I first spoke with Mary Ann who quickly responded to my email inquiry about an estimate and scheduled one right away for me. She proactively and thoroughly explained who would be coming out to the home, what to expect, and was always prompt with replies to my questions. Mike was
the gentleman who came out to estimate the project quoting a very fair price, provided good information and options, and answered all my questions and concerns. The team of Mike and Matt came out to install the radon mitigation system today and were on-time, efficient (3-hour install), personable, polite, and conscientious about clean-up. Mike even helped troubleshoot and fix one of my garage lights after the install- BONUS! I’m so glad to have found Guardian , and I would recommend them to anyone.
Thank you so much Mary Ann, Mike, and Matt for your great service!!
We had a Radon mitigation system installed by Guardian. I sought 3 different estimates because that’s what they say to do. We chose Guardian after meeting Chris the owner. He was so knowledgable and friendly, our calls were returned within an appropriate timeframe, and gave me better options of where the somewhat intrusive system could be placed without taking up half my basement ceiling where the others didn’t. The day of installation they showed up on time, there were 2 other men with him as he said there would be. They were all very friendly, knowledgable and professional as well. The system was installed without any problems and they cleaned up as he said they would. Cost wise, they are pretty much right in the same ball park if not a little cheaper. Chris made suggestions that could help contain the cost for my budget too. Just an honest guy. I would use Guardian again and would definitely recommend them in the future to my friends and family. I have since moved to a new house and used Guardian again. Even referred them to my mom to use. Still great service!
These are the kind of people you want to do business with! From the first phone call with Maryann to the end of installation, everyone was courteous, kind, and knowledgeable. I called a few companies to come out to give as a quote, based on many suggestions seen from other people in my situation. Guardian happened to be my 4th call after scheduling with 3 other companies. My first encounter with Maryann caused me to cancel my other appointments. She gave me specific details in that first call, including the fact that permits would be needed prior to work being started. I had no clue that would be the case, because no one else mentioned that. She was upfront about pricing, including the cost of permits. Even though the other companies may have cost a little less, I felt like I was going with someone who is transparent and really knows what they are doing. Chris and his team were of the same caliber; friendly as can be and they got the job done seamlessly and in less time than anticipated. They explained everything and showed a real passion for their work. Best of all, our radon is gone! Thank you for all that you do!
Had Guardian install our radon mitigation system. Highly recommend. Very informative. Mary Ann went over things in my initial phone conversation and when Chris came to check out the basement, he explained everything that would happen during installation. All went as planned, no hidden surprises. Showed up on time, finished on time and cleaned up!
What a great company to do business with, they were quick and efficient did an excellent job.. highly recommend.
Chris and his team showed up on time and were very professional. They made sure to keep the piping and electrical in areas that would not interfere with me later finishing my basement and cleaned everything up before leaving.
Best home repair / maintenance experience I’ve ever had. Chris and Mary Anne provide excellent customer service; they seem to be genuinely friendly people. Price-wise, they came in cheaper than the other quote I got. In addition to converting my radon mitigation system from passive to active, they also encapsulated my crawl space for a very reasonable fee. I was aware of some things that could come up during installation that would increase the cost, none of which occurred. Chris could have claimed that the complications existed and I would have been none the wiser. This demonstrates the honesty by which Chris conducts business. I also bounced a basic electrical question off of him, which he was happy to answer. His desire to ensure customer satisfaction is clearly exhibited with every action he takes. I highly recommend Guardian for your radon and electrical needs.
I cannot say thank you enough to Guardian Radon Mitigation! We were extremely impressed with their professionalism from the moment I first call to the day our system was installed! Chris came out and explained everything thoroughly and quoted us on a new system, within a week it was installed and working! After talking with friends the other day they too mentioned what a wonderful company Guardian is to deal with. There business practice if fantastic and I look forward to recommending them in the future.
Tip.. I was concerned about the new color of our system on the outside of our home and they did an exact match that looks identical and blends extremely well!
We had received quotes from multiple companies, but Guardian was the easiest to work with. From Mary Anne with the initial phone call and explaining the process, to Mike who did our quote and install. Everyone was super nice and never tried to oversell. They had a fair price and the quality of work was fantastic. Would recommend them to anyone!
Great results and great service. They had to come back to address slightly elevated levels and went above and beyond to do so.Great results and great service. They had to come back to address slightly elevated levels and went above and beyond to do so.
Need a radon test? Need radon mitigation? Guardian Radon and Electric is fantastic. Mary Anne and Chris are prompt and I have never been more informed about work being done to the house. Mary Anne is on the ball! From leaving recording her message telling me I wouldn’t hear back until Tuesday after a holiday weekend to explaining everything that would happen when I first called. Mary Anne even called me back to tell me she had no new information when she promised to call back with information. Usually people just wait to call you right? Not Mary Anne. Chris came out as promised and gave me all the options and starting fresh was cheaper than using the existing skeleton system. They even have lock box access so no worries if you have already moved to your new home. Our 2nd radon test was almost 0! There were no surprises and I couldn’t be more pleased with their service. If I was still in the area, I would definitely call them again.

Everything about this company is excellent; from the super helpful office staff over the phone, to the knowledgeable installers that gave detailed explanations of everything, while answering all questions asked.
Chris and his team were great! Mary Ann was great to talk to and help set up my appointments. They were on time, friendly, fast and very efficient. The works looks great and I couldn’t be happier with having all my questions answered. An estimate and the complete job all within a week! Thanks Guardian
Excellent Service – The team was on time, professional and courteous. A job well done.
I’m a Realtor and broker owner of MODE 1 Real Estate. I have referred my clients to Guardian for years and just last year, decided to install a mitigation system in my own home. 1. I recommend to every homeowner to install a mitigation system regardless if you test or not.
2. Peace of mind- you can feel at ease knowing you’ve lessened a proven carcinogenic element from your home.
3. Make life easier- when you go to sell there’s a myriad of things to worry about and prep for. Make the radon test one less thing to stress about.
4. Quality- using Guardian was a no brainer for me. I know I’m receiving reliable, knowledgeable, and dependable services as well as taking care of my clients when we use Guardian for Radon and Electrical services.
Absolute professional job. Neat and quality installation. I just moved into a townhome and was having a tough time getting through my HOA red tape. MaryAnne was a huge help in taking care that end of the project. I have already recommended Guardian to my neighbor.
We’re so thankful for Guardian!! From start to finish Guardian has been courteous, professional and educational. We’re selling our home and during inspection found the radon results were a littler higher than standard guidelines. We didn’t know anything about radon so it was unsettling to hear we needed to mitigate. Mary Ann was fantastic in explaining the process. Mike came out and made us feel calmer as he explained the process. Mike and Matt returned to install the system. Very wonderful crew! Down to earth, kind, and friendly. Thanks to all of you 😊
First and foremost, THANKS!!!! What a great company. found out from neighbors moving, that they had high radon levels in the house. So we decided to test. Initially came back at 14.8. Holy Cow! Re-tested and came back little lower but not much. I have passed the Guardian truck many times on my way to work. Not thinking I would ever need them. But, thanks to them and their great workers and office staff, we have re-tested and now are below .4!!!!! Wow and thanks to a great company. I would recommend them to any and all who need mitigation….. Thanks again
A radon test was requested while selling my house and I found out I had higher than normal radon levels. I was given 3 recommendations and after talking to Guardian I found the right company. Their price was comparable to the others but their service was incredible. They explained everything step by step. They sent pictures of work done similar to what I needed. They have electricians on staff and ordered the building permit. Everything was completely taken care of. Also since I have already moved 2 hours away I didn’t have to do anything. They took care of everything! They made this process actually enjoyable! Thank you guardian. I hope everyone calls you if they need radon mitigation!
Customer service extraordinaire!!! Chris and team did an excellent job—right on time, lots of process explanation, very efficient and zero mess! Mary Anne is beyond helpful and coordinated related vendors for me. This company is what customer service is all about and I would recommend them to anyone!! So glad I found them, since I’m new to the area.
Just had them do our radon mitigation and would highly recommend them. The were everything you need – priced right, professional, prompt and thorough. The worked with us to get it done quickly. And we passed the retest easily.
Excellent and personalized service. We had a complicated area to treat; however with Guardian’s innovative system installation, we passed our retest with flying colors! The entire Guardian team was prompt, thorough, straightforward, and professional. Exterior system components were placed to essentially blend in with gutter downspouts. No eyesores!

Very knowledgeable and friendly company to work with. Scheduling was easy and convenient. This company goes above and beyond to make sure the system blends in on the exterior of your home. Highly recommend this company.
I just wanted to update everybody on my retest after Guardian put the mitigation system in.
The house before the mitigation system tested at 29.8 pCi/ L… And after the system, it tested at .3 pCi/L.
(Anything over 4.0 pCi/L needs to be fixed)! Thanks to Guardian were not surrounded by poison anymore!!
We are extremely happy with their service.
We could not be happier with the work done by Chris and his team. Extremely professional and quick. Very good communication with the office and the installation team. Thank you Linda Nickels Hoss (realtor) for recommending them.
Guardian was very great!
Mike and his associate came out and got the job done in a very timely manner. All of the work was done very top end. It looks as good as a radon mitigation system can, and they did an excellent job of keeping everything out of the way. They noticed that one of our outdoor outlets was not working and he offered to fix it at just the cost of the part. They also added in monitors to ensure that the system is functioning, and was very informative as to how everything worked. The price was very competitive also. Mike and his team are very easy to work with, and did a great job keeping everything neat and clean. 10/10 would hire again for any needs.
Mary Anne and the rest of the team were fantastic to work with during the whole process. We are attempting to sell our home and needed a good test result to get to the closing table. Mary Anne was so thorough and professional from the start, so I knew right off the bat I was in good hands. The guys that showed up were also on time, very early in the morning, and were in and out. I just got my test results back today and the radon system is working perfectly. I highly recommend you use Guardian Radon for your next mitigation system.
Chris and his team were incredibly knowledgeable and very professional. They did a great job installing a radon mitigation system. We saw a substantial improvement in air quality following installation of the system.
My experience with Guardian Radon Mitigation was a very positive one.
We were in the process of trying to purchase a home and during the inspection elevated Radon levels were found. I asked around to some of my trusted sources I was referred to Guardian. After speaking with Mary Anne I felt very comfortable that this was the correct company for us. She took care of all the details for me; setting up the time with the current home owners to get the estimate done, forwarding all the documents to everyone that needed them (realtors, lawyers, both sets of home owners), contacting me after we closed on the house to set up the appointment, and scheduling a third party company to come and do the retest after the system was installed. With everything else that was stressful with trying to close on the house, she was a huge help.
The install process went very smoothly. They were prompt and professional and explained the whole process to me as they went. They took the time to make sure the system was in a spot that was out of the way and looked as attractively as it could. After they were finished, they left the area cleaner than when they arrived.
I would definitely recommend using Guardian. If you do, a small tip that may help you out; Pay attention to what shirts Chris and Bob are wearing, unless they were standing next to each other, I was having a tough time keeping track of which one was which.
Positive: Professionalism, Quality, Responsiveness, ValueOnce I contacted them, they let me know all about Radon Mitigation and felt like part of the family. The prices were as quoted, fair and the work was performed cleanly and on time. If you need a Mitigation team, this is the place to contact.
Positive: Professionalism, Quality, Responsiveness, ValueChris and Mary Ann are the best. Wonderful, honest, professional and friendly service. The guys were thorough, courteous and did an amazing job. I highly recommend Guardian for radon mitigation and any electrical needs. If I could give more then 5 stars I would!! Thank you! ❤
Several months ago, we reviewed online comparisons of several brands of radon mitigation units, and also researched local radon mitigation companies on BBB, Yelp and Google. We obtained a couple of estimates, and finally chose Guardian Radon Mitigation & Electrical Services in Batavia,IL to install our radon mitigation unit. The technician came out promptly, he was very pleasant and polite. He explained our options with no pressure, and expertly performed the installation. We are 100% satisfied with the product, the technician and the Customer Service in the office. After the installation, we purchased an inexpensive home radon meter at our local hardware store to track our radon levels 24/7. Our average long-term basement radon level has dropped from 8 – 9 down to 1.5 – 1.75. Our short-term radon level is less than 1.0 even in the Winter. We highly recommend Guardian Radon Mitigation & Electrical Services.
I had an amazing experience with Guardian Radon. I searched Yelp and read the amazing reviews and called Mary Anne who is incredibly nice and up front with pricing and basic info I needed to get an estimate. Chris arrived on time for the estimate and was able to do a comprehensive walk through and outlined the price and work details required to get my radon system installed in my Naperville home, new build in 2009. I have a full finished basement and Chris and his team arrived promptly today to install the system and knocked it out in three hours and their work is impeccable, they are clean and extremely professional. I will only refer people to Chris from now on for radon mitigation. What a great experience! Do not go anywhere else – call this company. They matched also the piping with downspout pipe that is exactly the same color of my current clay colored downspouts. My pre system radon readings were done on a $200 handheld Corentium detector and registered between 5 and 9. Will update this with my post 1 week readings soon.
“Thank you very much for the outstanding job and service!”
We are Realtors and only recommend Guardian Radon for our clients! They provide fantastic service! They are 100% professional, reasonably priced and do quality work! Chris and Mary Ann are the best to work with! You can’t go wrong!!

I needed to do something regarding levels of radon affecting my indoor air quality (2nd leading cause of lung cancer) so I went online and got some quotes. Mary Anne at Guardian answered my call and thoroughly explained the process and through pulling up my address in the MLS Database, already knew the details of my house without even asking all the redundant questions about my property! I was impressed and had a good first impression. Within a couple of days, Mike came out to my house for a free consultation and explained to me exactly where he would be installing the fan housing, PVC pipes, and drilling the holes to connect and vent out the air underneath our cement foundation. My sump pump would also be properly sealed. He also explained to me the correct way to do it in regards to industry and IL standards and I was very impressed with his attention-to-detail and straight-forward, “no BS” approach. After a few back and forth emails with additional questions, I was further impressed with the way they addressed my initial concerns (3 or 4 inch wide piping?) and along with them honoring the initial fair + upfront quote given to me during my first phone call, I decided to hire them and booked the installation for the soonest available day. The next week, the owner Chris, along with Mike came out as a team of two to complete the actual job. (One of them is also an electrician.) The whole process went smoothly as Mike was busy with the basement work and Chris was busy with the work on the exterior of my house. A good way to divide things up! The work they did was quite professional and their workmanship exceeded my expectations! (I even noticed Chris using an I-beam level to perfectly balance the quality radon fan they installed on the exterior of the siding and everything was weatherproofed sufficiently with a clear sealer!) The whole job took roughly 5 hours and they cleaned up afterwards. Mike explained to me what to pay attention to down the line, even weatherproofed an old, exterior no-use hole and removed an old aluminum foil tubing connected to that hole. My U-Tube Manometer measured a good amount of suction at 1.75 inch WC. Fast forward 72 hours later and my EPA-approved continuous monitoring device now shows a negligible 0.6 pCi/L radon reading as of Sunday! (well below the EPA’s 4.0 pCi/L action level and the WHO’s 2.7 pCi/L action level) So as I’m writing this….Mission Accomplished is my conclusion. I would definitely recommend Guardian Radon Mitigation to anyone looking for a tight-knit family of professionals who truly get the job done right the first time.
We love Guardian Radon Mitigation. Not only have I used them to install the system in our personal home but I recommend their team to all my clients! You will not be disappointed!
Prompt, knowledgeable, professional. I’ve been wanting to get this done for the past few years but worried about finding a reputable company. My co-worker highly recommended Guardian and I now highly recommend them, too. Mike and Matt were my installation team. The day before installation I discovered my sump pump wasn’t working (sump pump cover needs to be sealed as part of the radon mitigation process) and I was also concerned about some wonky electric wiring in my crawlspace, for an affordable price, they installed a new sump pump and fixed the wiring (Mike is a licensed electrician), the same day they installed the radon mitigation system. I’m very happy with the completed job and have tremendous peace of mind.
Excellent experience with this company, specifically Maryann and Chris. They were professional, on time, clean, knowledgeable and coordinated SO much for our schedules. Answered all my questions about Radon, etc. I’d recommend them to family.
Chris came to our house on short notice, and patiently waited for me (I was delayed by 20 minutes). I was embarrassed for my tardiness but was still greeted with a large smile, which made me at ease right away. Chris did a very fair estimate, and was at my house 2 days later to install the system and put me at ease. Great service, great attitudes, great communication, great price. I highly recommend this company.
Positive: Professionalism, Quality, Responsiveness, ValueI am glad/ lucky I found these guys. Mary Anne was professional when scheduling and informed what time they will come and they came on time. They did the job professionally, really well. House was kept clean in process, the guys were humble and nice. Chris was so nice and patient in explaining everything. I asked him tons of questions and he kept on answering them.
Excellent service all along the way. From the beginning they responded to my requests within minutes. Worked through a fair quote. They offered me options. Then set up an install time that worked great with my schedule. The install looked great and they were careful to put it in a place that was effective and that looked good with the surrounding walls. I was impressed at the care they took in cleaning area and protecting the floors. Incredibly friendly and knowledgeable. We would hire them again.
Chris and his team were true professionals throughout the entire process beginning with my initial phone call. Chris came to my house for the estimate in 20 min. He explained the entire process and scheduled installation 4 days later. They arrived on time for the install and completed the project with no issues. Follow up communication with my realtor was handled by Guardian. Excellent communication via email.
“Great service ! We were under the wire on closing our house, they were quick to respond and very efficient. We truly appreciate it.”
Positive: Professionalism, Quality, ResponsivenessInstalled a Radon Mitigation System for me. The Business Manager, Mary Anne Bice was very informative and helpful. Mike and his assistant(sorry, don’t remember his name) explained clearly what they were going to do and where. The installation went well and they cleaned up nicely when the job was completed. I highly recommend Guardian Radon Mitigation & Electrical Services.
Chris and Mary Anne with Guardian were fantastic. I would and do recommend them to anyone who is going to be finishing their basement to get the radon out. The customer service was second to none. Great people, work, and company. Thank you for a fresh basement!
I want to thank and recommend the Guardian Radon Migration & Electrical team. In selling our home is was discovered our builder only installed part of the radon migration system. I called and spoke with Mary Anne who it only explained everything, but she saw me through the entire process start to finish. They kept me informed and did what they said they would do. They even pulled my permit. Chris came out gave us the estimate and told us of additional things that needed to be done. Such as electric had to be added in my attic. They did that too. They scheduled the job. They showed up on time and did the work in a fast and efficient manner. They were very professional and neat. They even set up the actual radon test for me with another company. Bonus! I did not have to worry or do any of that. So if you are in need of a Radon Migration System, I highly recommend this company.
We decided to test our house for Radon, and found our living space to be between 4 and 5 pCi/L. The estimate from Guardian was free, quick, easy, and the quote was competitive. The installation was professional, clean, and quick. In 24 hours our readings dropped to extremely safe levels of 0.5pCi/L. Thank you Gaurdian, we will definitely recommend your services.
My home has historical radon levels in the basement that hovered around 4 pCi/L for years, which was arguably safe for non-living space, but border line. I finally decided it needed to be safer and I reached out to Guardian for help. One phone call and a couple site visits later, all in quick succession, and now there’s effectively no radon anywhere in the house. Very little disruption in the home, Chris and Mary Anne were very easy to work with, and the crew doing the install was careful, professional, and friendly. If you have radon in your house, or don’t know, don’t wait until you’re selling your home to deal with it. It’s a serious health risk that you actually have the means to control.
Positive: Professionalism, Quality, Responsiveness, Value
I have had Guardian complete radon mitigation in two homes now, and I have been satisfied with both projects. Friendly, knowledgeable service – they can answer any questions you have and the price quoted was the price paid, with each item explained. Thanks!
I am very impressed with Guardian. From the first call with MaryAnn to the completion of the work. She was clear and concise on what the potential cost would be due to my basement setup (crawl and basement). Chris was on time for the initial meeting and completely thorough in his explanation or what needed to get done. He was able to do the install at the lower end of the initial quote. He showed me pictures explaining what it would look like. He told me his team would be at my house by 6:50am and ready to go into the basement at 7 and they were. The team that did the work was punctual, organized and very neat. I would highly recommend this company!
I highly recommend Guardian Radon Mitigation and Electrical Services. We scheduled to have a mitigation system installed with the purchase of our new home. Levels were slightly elevated, but after reading about the potential for long-term effects, we didn’t want to risk it with a young family.
Everything went so smooth – really all we had to do was schedule the appointment! Everyone on the Guardian team is friendly, courteous and knowledgeable. They will clear up any questions you may have and guide you on the best ways to test radon levels going forward. Highly recommended.
I am in need of radon mitigation at my house. I was not certain exactly how to go about even finding someone. I came upon Guardian Radon and discovered they have a Facebook site. Within minutes of inquiring, they were honest and told me they do not service my area. However, they were quick to point me in the right location of how to find a licensed professional. I greatly appreciated their honesty and assistance!
Chris, Maryann and their entire team are very professional, courteous, and really know their business. You can feel confident they will reduce radon levels to below EPA standards. This was my second house they did and couldn’t be happier. My radon was 5.6 they reduced it to .05. Now can close without any problems. Thanks Guardian best wishes for your continuing success.
Working with Guardian has been one of the very best experiences we had while selling our home. No one wants to learn that they have an elevated radon issue, but after the buyer’s radon tester discovered it, we immediately reached out to Guardian for mitigation and we are so happy we did. Mary Anne and Chris are both extremely professional and friendly! The work was done quickly, cleanly, and right on schedule. The post-mitigation test showed excellent results! We could not be happier. I would definitely recommend them to anyone who needs help with radon mitigation. I’d give them 10 stars if I could! Thanks, Guardian!
