Certified Radon Mitigators
in Dayton, Ohio

Dayton and Montgomery County sit in the Miami Valley of southwestern Ohio, where glacial till and outwash over Ordovician limestone create radon conditions that are moderate to elevated across the metro area. Montgomery County is EPA Zone 2, but Dayton-area homes — particularly those in older neighborhoods like Oakwood, Kettering, and Beavercreek in adjacent Greene County — test above the action level frequently enough to make testing standard practice. Dayton's housing stock is dominated by mid-century construction with full basements, and the metro has solid certified contractor coverage with competitive pricing. Ohio requires state certification for radon contractors.
