Radon Risk in Cleveland
Cleveland and Cuyahoga County sit in EPA Zone 1, an area with elevated radon risk. The U.S. EPA estimates that approximately 40% of Cleveland-area homes test above the 4 pCi/L action level, driven by Erie lakeshore geology and glacial deposits that concentrate radon from underlying shale and limestone bedrock. Testing and mitigation are strongly recommended for all homes with basements or ground-floor living spaces.
Why Radon Testing & Mitigation Matter in Cleveland
Older Housing Stock
Many Cleveland homes, especially in Lakewood, Rocky River, and the eastern suburbs, were built before 1950. These older homes often have unfinished basements, poor weatherproofing, and direct soil contact — all conditions that allow radon to accumulate.
Geology & Climate
Northeast Ohio's glacial deposits and limestone bedrock naturally release radon. Cold winters mean homes are sealed tight for months, maximizing radon accumulation indoors.
Health Risk
Radon is the second leading cause of lung cancer after smoking. The EPA action level of 4 pCi/L is a safety threshold — any level above it warrants testing and potential mitigation.
Affordable Mitigation
Most Cleveland-area homes can be mitigated in a single day with sub-slab depressurization or crawl space sealing. Costs are typically $1,200–$2,500 for a standard system.
Ohio requires state licensing for radon mitigation contractors. All contractors shown are NRPP or NRSB certified. To verify state licenses, visit the Ohio Department of Health Radon Contractors Directory.
