How Do I Know If My Home Has High Radon?

If you’re asking this question, you’re already ahead of most homeowners.

As an Illinois licensed radon measurement professional (RNM2015202), I’ve been performing radon testing since 2015 in residential, commercial, daycare, and multi-family buildings. Over the years, one thing has become clear: you cannot identify elevated radon levels just by looking at a home. You have to test.
