Radon Mitigation in Cleveland, Ohio
Cleveland sits in EPA Zone 1, a high-radon area where approximately 40% of homes test above the 4 pCi/L action level. Radon mitigation is essential for protecting your family's health.
Why Is Radon Elevated in Cleveland?
Cleveland's elevated radon levels result from the region's unique geology. During the last ice age, glaciers deposited thick layers of glacial soils across northern Ohio, covering bedrock rich in radium and uranium-bearing shale and limestone. These geological formations naturally emit radon gas, which seeps through soil and accumulates in homes—especially those with basements or ground-level living spaces.
The Great Lakes region's proximity to Lake Erie further influences radon transport through groundwater and soil moisture. Cold Ohio winters seal homes tightly for months, maximizing indoor radon accumulation. Combined with many Cleveland-area homes built before modern construction standards, radon mitigation has become a health priority for the region.
Health Risk
Radon is the 2nd leading cause of lung cancer after smoking. EPA recommends fixing your home if radon levels exceed 4 pCi/L.
Simple Solution
Sub-slab depressurization can reduce radon by 50–99% in a single day. Most systems cost $1,200–$2,500.
