Radon Testing & Mitigation in Idaho Falls, ID

Idaho Falls is the anchor of Bonneville County and the largest city in Eastern Idaho, and its radon picture is shaped by the same Snake River Plain geology that runs under the whole region, volcanic and sedimentary ground that gives the area some of the highest radon potential in the country. The Idaho Department of Health and Welfare estimates roughly 2 in 5 Idaho homes test above the EPA action level of 4.0 pCi/L, and Idaho Falls homes are no exception regardless of neighborhood or age.

The city's housing runs a wide range, and different parts call for different radon approaches. The historic core near the Numbered Streets and the older Bruce and Hawthorne neighborhoods has homes dating back decades, many with full basements or older foundations that have had time to settle and develop the cracks and joints radon uses to get indoors. The newer East Bench and West Bench subdivisions are mostly modern slab or basement construction on the same radon-producing soil. Whether your home is a 1920s bungalow downtown or new construction on the Bench, testing is the only way to know your level.

For older Idaho Falls homes, sub-slab depressurization handles most basement and slab foundations, while any home with a crawl space uses sub-membrane depressurization instead. For newer construction, it's worth asking whether a passive radon rough-in was built in, and testing once the home has been through a winter.
