How to select the “right” Radon Mitigation Professional

Whether you are a homeowner or a real estate professional ~ there are some guidelines to use when selecting the right Radon Professional for the job!

How should you select a contractor?

As with any home improvement project there are some “must haves” when evaluating your professional.

1.) Did the contractor inspect your home prior to providing an estimate?

We receive calls daily from perspective homeowners and real estate professionals as well as attorneys asking “Can you give me an estimate on the phone or do you have to come out?” Yes, they should “come out.” The purpose of an onsite estimate is to properly evaluate the home in the state it is in ~ to avoid surprises, and that goes for the client and the installer. Perhaps the home has a finished basement along with a gravel crawl space. What does that mean to you when having the work performed? How will that contractor reduce radon levels in both areas?

2.) Will the contractor provide photographs of work and/or references?

Easy enough to ask for and you should!!

3.) Did the contractor explain to you what work needs to be done? Did they set your expectations on length of the job, materials used, and how the system will “work” after installation?

Many people just don’t know, some are not interested and others don’t think of asking. It’s okay to quiz the potential contractor about these things. Why leave people guessing??

4.) Did the contractor ask for the pre mitigation test levels and the report? 

It is important as a mitigation professional to understand what you are working with. For example, a finished basement has some natural limitations as you do not want any part of the system to be visable in your finished area. Understanding your pre mitigation levels will help the contractor determine how many suction points need to be used, what type of fan to use (one size does not fit all) and other potential road blocks during installation they need to look for. It’s more important than you may think.

5.) May I see your insurance please?? How bout seeing that license too?

Absolutely!! Look for not only their General Liability Insurance as a business, ask for their Worker’s Compensation Insurance too. What if they were hurt while working at YOUR home? Make sense?? Protect yourself.  Ask to see their Radon license. You’d be surprised…there have been some companies here in Illinois that market themselves as “Environmental Experts” – that does not necessarily mean they are licensed to do radon work.

The Contract

Every contract should contain the following at a minimum ~ scope of work, warranty terms and exclusions (yes there are some), start date and completion date, total cost of the job, transferability of the warranty and payment terms. Pretty basic stuff but quite important.

In Closing

We can’t stress this enough, all radon mitigation systems are not created equal. Be sure and select the contract providing the best value. Take into account that a less expensive system may have higher overall operating costs – those costs never go away! Take into account the type of building materials and the technique best suited for your home. Will this system be in line with the aesthetics of your home or will is stick out like a sore thumb? Here in Illinois you can visit the IEMA website to find licensed radon mitigation professionals in your area – the rest is up to you!

Radon Levels and Renters ~ What Every Tenant Should Know

Unlike homeowners, many renters do not have the professional guidance such as a realtor or attorney when they are looking to sign for a new lease. Renters therefore infrequently will do their due diligence with regards to having any home inspection performed, or environmental testing such as a radon test prior to signing their lease. Here lies the problem ~ as a renter you may be signing for lease unaware of any potential dangers in the home or apartment. As of December 29, 2011 approximately one-third of Illinois housing was being rented (Source: IEMA Press Release)

Illinois passed a  “new” law on January 1, 2012 to help renters learn more about Radon levels in their home.  If the building that you are living in has been previously tested for Radon, the landlord is required to inform you in writing that a radon problem may exist. Prior to signing your lease, be sure and ask about this. If the home or building has NOT been tested, then conduct your own radon test either with a home test kit or licensed testing company. The IEMA recommends that all homes be tested below the third floor. Because Radon is a soil gas, the highest levels are likely to occur in the lowest levels. 

What can you do if you find elevated Radon levels in your place of residence?

Because radon mitigation is considered a remodel project and requires repairs to the building, it is often the landlord or building owner that would have to authorize having the repairs done – not the tenants. If your home has high levels of Radon there are steps that you as the tenant can take to see that the problem gets fixed.

1.) Inform the building owner in writing that the home has tested elevated for Radon 
Gas. Be prepared to provide a copy of the radon results. Ask for details from the owner on how they plan on fixing the problem. 

2.) If you live in an multi-unit building, share your information with your neighbors and encourage them to do their own testing. Remember, just because your unit has tested elevated, there may be other areas of the building that do not. Once others have confirmed, we recommend the same steps be taken. Present the information in writing to the building owner. 

Useful Tenant Checklist:

*Check the building that you live in. Has it been tested for Radon? If so, ask for the results in writing. If it has not, perform a test yourself or hire a licensed testing company to do so. 

*If your radon levels are at 4.0 pCi/l or higher, present to the building owner in writing with a request for further testing and/or installation of a radon mitigation system. 

*If your rented home or unit has elevated levels and you are in need of further assistance, contact the IEMA Radon Hotline at 1-800-325-1245

Lastly, with regards to Radon levels in any type of real estate transaction –  purchase, lease or rentals, Illinois has mandated a “disclosure law” only. Be sure and do your due diligence and protect yourself and your family. With this law now in effect, it is a step in the right direction for tenants in Illinois.

Radon Levels and the Value of Time

When speaking with customers on a daily basis, they often ask about their radon levels and how long they’ve been exposed. One client asked “I used to ride my bike in my basement as a kid, then moved my bedroom down there ~ am I doomed??” Our advice is always, don’t throw in the towel just yet. As an advocate for Radon Education, we want to provide information in relative terms for everyday use – so here it goes……

When we hear of radon readings, in the terms of pCi/L and the “number” what does all that stuff mean?? All of the radon information that is produced in the marketplace takes into consideration that you are exposed 70% of the time. So, we know that we spend our hours sleeping in our home, spend time before and after work and school, and spend time on weekends and other occasions. This type of lifestyle represents 70% of our time being spent in our homes. So let’s use the example of 4 pCi/l – by now you may know that the level of 4 is equivalent to a non-smoker smoking 8 cigarettes per day. Let’s look at a few different scenarios and potential impact.

Scenario 1:  You have a home based business or you are allowed to work from home or are a stay-at-home parents or retiree. In this case a radon reading of 4 pCi/l is much, much more significant – because you are home in excess of the average 70%. In this case, you may leave only to do errands and everyday occurrences. Your relevant exposure is going to be higher in this case therefore potentially having a much bigger impact on your long term health.

Scenario 2: You have a job that requires you to travel for work the majority of the week such as outside sales, training or a consultant to name a few. This type of person is actually exposed less than the 70% average for the pure fact that they physically are not home as much. Make sense??

Wrapping it all up –

Your time exposed is multiplied by the amount of radiation –  which equals your dose. So if you live in a home with 1 pCi/l for 7 years, it’s the same as living in a home with 7 pCi/l for 1 year. It’s the same amount of exposure in both cases. If you are fortunate enough to live in a home where your radon reading is 1.3 pCi/l to 1.5 pCi/l then your home is considered “average.” Keep in mind other radiation exposure such as X-rays for medical/dental, cell phones, even Cosmic radiation emitted from the atmosphere. Radon is the single greatest contributor of radiation to the average person and accounts for more than 50% of your families total radiation exposure of their lifetime. As always….test, test, and test. Once this is done – mitigate as necessary. This is definitely something that you can control and provide protection for your loved ones!!
