You’ve found radon in your home – what should you do?

First, don’t panic!

Radon is everywhere and fixing a radon problem is very straight-forward, and easy to do with a professional radon mitigation contractor.


… if you have performed only a single test, the US EPA recommends a followup test before fixing your home. Radon levels fluctuate naturally and it is important to know if the initial test was an accurate assessment of your home’s average radon level or whether the high levels could have been caused by unusual weather.

How To Follow Up Your First Test

If your first test has a result between 4 and 8 pCi/L, you have the choice of testing again. If results are needed quickly, you can re-test with a short-term (2-7 days) device. For a better understanding of your home’s year-round average, you can test with a long-term (3-12 months) device.

If the results of your first test are higher than 8 pCi/L, then it is recommended that you test again using another short-term test device. The higher the radon concentration above 8 pCi/L, the sooner you should conduct a retest.

Interpreting Your Follow Up Results

If you are involved in a real estate transaction, the EPA recommends fixing the house prior to sale if the average of your original and follow-up tests are 4.0 pCi/L or higher.

If you chose a long-term device for your second test, the EPA recommends fixing your home if the follow-up result is 4.0 pCi/L or higher.

If the results of your followup test with a short-term test are still 4.0 pCi/L or higher, you are urged to consider fixing your home.

If your followup test results are below the 4.0 pCi/L EPA action level, you should test again sometime in the future because your initial test has shown that your house has the potential to produce high radon levels at times.

"The technicians at Trinity services were extremely professional. It was a pleasure to open up our home to them. My wife and I were extremely impressed with how neat and clean they worked. A lot of contractors just don't care, but I could tell that Trinity was not one of those contractors."

Bruce – Naperville, IL

"I met Josiah last week when he came out to 310 S Rosedale in Aurora to consult with my clients about the house they are buying. I was very impressed by both his knowledge and wiliness to answer questions. Far too many in the trades are not quite so customer centric. In any case, it is my pleasure to recommend your company to other agents and to my own clients in the future."
