Certified Radon Mitigators
in Nashville, Tennessee

Nashville and Davidson County sit in the Central Basin, where Ordovician limestone and the area's karst geology produce moderate radon across much of the metro area. Middle Tennessee is EPA Zone 2, with Nashville-area homes averaging below the action level — but individual homes in neighborhoods like Green Hills, Belle Meade, and the rapidly developing Williamson County suburbs see readings above 4 pCi/L with enough regularity to justify testing. Nashville's housing boom has brought more certified radon contractors to the market. Tennessee does not require state radon contractor certification.
