Crawl Space Radon Mitigation in Clintonville, OH

Crawl Space Radon Mitigation in Clintonville involves sub-membrane depressurization: a 20-mil polyethylene liner sealed to the crawl walls with an inline fan drawing soil gas from beneath, working on the crawl-space envelope where ground-source soil gas enters through bare earth. The service is the right scope for any crawl-space-foundation home testing above 4.0 pCi/L, in place of sub-slab depressurization which does not apply to crawl spaces.

Clintonville's 1920s through 1950s bungalow and Cape Cod stock sits on full basements, and sub-slab suction routing is straightforward given the small, consistent basement footprints along the High Street corridor. The neighborhood has produced some of the highest documented pre-mitigation pCi/L readings in Franklin County, consistent with the Devonian limestone and shale bedrock under this stretch of the Olentangy valley. Older homes with a finished basement level need the same interior-to-attic stack routing common across the metro's pre-war stock. Clintonville runs along the Olentangy River's east bank, with Whetstone Park and the Olentangy Trail tracing the river through the middle of the neighborhood. Clintonville sits on geology that drives elevated regional radon exposure across the Columbus metro, including Franklin County.

Franklin County crawl-space work is uncommon inside Columbus and its poured-basement suburbs like Dublin and Hilliard, where full basements or slabs dominate, so this scope concentrates on the small share of older outlying parcels near the county line where crawl-space construction survives from before the county's subdivision-era building boom.

ANSI/AARST CCAH-2020-0523 requires membrane sealing and a manometer verifying continuous negative pressure across the membrane. The Ohio Department of Health Radon Licensing Program oversees radon program compliance for Clintonville, and Ohio licensure under ORC 3723.02 applies to any contractor performing mitigation work in the state.
