Certified Radon Mitigators
in Bismarck, North Dakota

Bismarck and Burleigh County sit in EPA Radon Zone 1, with radon risk driven by North Dakota's position as a top-five radon state nationally. Central North Dakota's Williston Basin geology — uranium-bearing shale and alluvial deposits along the Missouri River — produces significant radon that testing consistently confirms. Bismarck's full-basement housing standard and prolonged heating season (October–April) concentrate radon at levels that frequently exceed the EPA action level. The state's smaller contractor market means longer scheduling windows, especially in spring.
