Radon Testing & Mitigation in Pocatello, ID

Pocatello is the Bannock County seat and the largest city in Southeast Idaho, and its radon picture is more serious than the federal map suggests. The EPA lists Pocatello as Zone 2, predicting moderate levels, but the measured county average runs closer to 7.0 pCi/L, and around 41 percent of tested homes come back above the 4.0 pCi/L action level, with some zip codes reporting over half of homes testing high. The Portneuf Valley's geology drives that, and it affects every part of town.

Pocatello's housing is unusually varied, and different areas call for different radon approaches. Old Town and the historic neighborhoods near downtown and Idaho State University have homes dating to the early 1900s through the 1940s, many with crawl spaces, partial basements, or mixed foundations layered on over decades. Those older foundations tend to have the cracks, joints, and settling that let radon migrate indoors, and they often need sub-membrane depressurization or a combined system rather than a simple sub-slab install. Newer construction on the benches sits on the same radon-producing ground and is typically a more straightforward sub-slab candidate if a test comes back high.

Whether your home is a century-old Old Town house or newer bench construction, testing is the only way to know your level, and given Pocatello's numbers, it's genuinely worth doing. Submit your address below and we'll connect you with an experienced independent local provider serving Pocatello.
