Certified Radon Mitigators
in Louisville, Kentucky

Louisville and Jefferson County sit on Ordovician limestone bedrock overlain by river-deposited alluvium and glacial till, producing moderate to elevated radon across the metro area. Kentucky's northern counties — including Jefferson, Oldham, and Shelby — have higher radon readings than the central and eastern parts of the state, and Louisville-area homes with basements or slabs at ground level benefit from testing. The Louisville metro has good certified contractor availability, partly driven by its proximity to the active Ohio Valley market. Kentucky requires state certification for radon mitigators through the Cabinet for Health and Family Services.
