A lot of people ask us about houses with crawlspaces and whether they need to be tested for higher radon levels. The assumption is that the radon is vented out the crawlspace vents and therefore the radon levels are lower in a home with a crawlspace (vs. basement). While that may be true, the only way to know if your house has high levels of radon present is to do a radon test. The EPA also recommends that you re-test every few years so you know that the levels haven’t changed because they can change over time due to barometric pressure or atmospheric conditions. So even though a home has a vented crawlspace, it’s a good idea to do a radon test, either when you purchase it or every few years!
By the way #1: the radon levels in this home was around 6.6, which is higher than the EPA’s recommended cutoff of 4.0.
By the way #2: Since July 1st, 2022, Colorado requires all radon measurement professionals to be licensed, so make sure that anyone performing a radon test for you has their CO license to do so. And of course, Front Porch uses licensed professionals: Jed’s radon measurement license is #138 in the state!
