Crawl Space Radon Mitigation in Pickerington
Crawl spaces are mitigated with sub-membrane depressurization: a sealed plastic membrane laid over the soil and a fan drawing from beneath it. Ohio's standards set the membrane at 6 mil polyethylene or heavier where the crawl is used for storage, with 12-inch sealed overlaps and mechanical fastening to walls and piers. Split-levels and ranch additions often pair it with sub-slab suction under the basement or slab. Pickerington sits within our service area for Greater Columbus and Central Ohio, with same-week scheduling typical for routine jobs.

Crawl Space Radon Mitigation in Pickerington: Fairfield County growth suburb, overwhelmingly post-1990s subdivision construction foundations and Columbus-area geology
Crawl Space Radon Mitigation in Pickerington 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.
Pickerington's housing is almost entirely post-1995 subdivision construction on poured concrete basements with a built-in sump, giving a mitigation contractor a clean, consistent suction point across most of the city. Fairfield County sits in EPA radon Zone 1, and the till-plain soils over shale common to this part of the county keep readings elevated regardless of how new the foundation is. Pickerington sits on geology that drives elevated regional radon exposure across the Columbus metro, including Fairfield County.
Fairfield County crawl-space work shows up on the rural parcels surrounding the county's historic courthouse-square towns rather than within them, where till-plain soils over shale keep soil gas present under both foundation types, and encapsulation ahead of depressurization is the standard sequence on the older farm-adjacent stock.
ANSI/AARST SGM-SF-2023, the standard for existing homes, calls for a sealed membrane and a system monitor, typically a manometer, showing continuous negative pressure beneath it. The Ohio Department of Health Radon Licensing Program oversees radon program compliance for Pickerington, and Ohio licensure under ORC 3723.02 applies to any contractor performing mitigation work in the state.
