Radon Mitigation Systems in Blue Ash, OH

Radon Mitigation Systems in Blue Ash involves sub-slab depressurization with an inline radon fan, sealed slab penetrations, and an exterior discharge stack above the eave line, working on the slab-to-soil interface and any below-grade openings where soil gas enters the home. The service is the standard installation for any Cincinnati home testing above the EPA action level of 4.0 pCi/L on a 90-day or annual long-term average.

Blue Ash's 1950s-1970s ranch stock sits mostly on full basements with block walls and slab floors poured directly on grade without a membrane. Many of these basements were finished in a later renovation, which both raises the exposure level and complicates access to the perimeter for a suction point. Blue Ash sits on the Cincinnati Arch geology (fractured Ordovician limestone and shale) that drives elevated regional radon exposure across the entire Greater Cincinnati metro, including Hamilton County.

Mitigation systems installed in Ohio must meet ANSI/AARST CCAH-2020-0523 for existing dwellings and be installed by a contractor licensed under ORC 3723.02 (Ohio Department of Health Radon Licensing Program). The Ohio Department of Health Radon Licensing Program oversees radon program compliance for Blue Ash, and Ohio licensure under ORC 3723.02 applies to any contractor performing mitigation work in the state.
