Crawl Space Radon Mitigation in Dublin
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. Dublin sits within our service area for Greater Columbus and Central Ohio, with same-week scheduling typical for routine jobs.

Crawl Space Radon Mitigation in Dublin: post-1995 golf-course and corporate-corridor subdivisions around a small pre-1900 river village core foundations and Columbus-area geology
Crawl Space Radon Mitigation in Dublin 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.
Dublin's post-1995 subdivision stock sits mostly on full poured basements with a sump pit already in place, and many carry a passive radon vent stack installed under the state's radon-resistant new construction code, ready for fan activation rather than a full sub-slab retrofit. The small Historic Dublin core along the Scioto predates that code entirely, and its handful of older structures sit on shallower foundations with less predictable soil-gas paths. Central Ohio's EPA Zone 1 designation and the glacial till under both halves of the city mean elevated readings are common regardless of which foundation type a given house has. Dublin straddles the Scioto River, and much of its post-1995 subdivision growth sits on the river's floodplain terraces and the bluffs above them. Dublin sits on geology that drives elevated regional radon exposure across the Columbus metro, including Franklin / Delaware / Union 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 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 Dublin, and Ohio licensure under ORC 3723.02 applies to any contractor performing mitigation work in the state.
