Certified Radon Mitigators
in Cleveland, Ohio

Cleveland and Cuyahoga County have significant radon risk driven by Erie lakeshore geology and glacial deposits that concentrate radon from underlying shale and limestone. The EPA classifies much of northeast Ohio as Zone 1, and Cleveland-area homes — particularly older housing stock in Lakewood, Rocky River, and the eastern suburbs — frequently test above the action level. Cleveland's aging housing inventory (many homes built before 1950) often has unfinished basements and limited weatherproofing, which can complicate mitigation routing but rarely prevents an effective installation. Ohio requires certified contractors for radon work.
