Crawl Space Radon Mitigation in New Albany, OH

Crawl Space Radon Mitigation in New Albany 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.

New Albany's post-1995 master-planned housing sits almost entirely on full poured concrete basements with an interior sump pit built in from the start, which makes standard sub-slab depressurization the low-disruption default here. Larger custom-built homes on the community's bigger lots sometimes combine a basement with a crawl-space addition, which can call for multi-zone mitigation rather than a single suction point. The small original village core on the Licking County side predates the master plan and has older, shallower foundations that need to be assessed on their own terms. Rocky Fork Creek runs through the master-planned community, and New Albany's footprint straddles the Franklin and Licking County line, a legacy of the original 1837 village sitting on the Licking County side. New Albany sits on geology that drives elevated regional radon exposure across the Columbus metro, including Franklin / Licking 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 New Albany, and Ohio licensure under ORC 3723.02 applies to any contractor performing mitigation work in the state.
