Radon Mitigation Systems in Upper Arlington, OH

Radon Mitigation Systems in Upper Arlington 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 Columbus home testing above the EPA action level of 4.0 pCi/L on a 90-day or annual long-term average.

Upper Arlington's pre-war and mid-century housing sits mostly on poured or block basement walls, and standard sub-slab depressurization performs well across most of the stock. Mature landscaping and limited interior chase access on the older streets often push the radon stack to an exterior routing rather than up through a closet to the attic. Franklin County's EPA Zone 1 designation and the Devonian bedrock underneath keep elevated readings common across the suburb's full range of building eras. Upper Arlington's eastern border runs along the Olentangy River, separating it from Clintonville and the Ohio State University campus across the water. Upper Arlington sits on geology that drives elevated regional radon exposure across the Columbus metro, including Franklin County.

Franklin County installs run on Devonian limestone-and-shale bedrock under a glacial till cap, and the county's EPA Zone 1 designation applies evenly across both the aged, cracked slabs common in Columbus's older neighborhoods and the more uniform poured basements of newer suburbs like Dublin and Hilliard, so the install method tracks foundation type more than location within the county.

In Ohio, radon mitigation is licensed work under ORC Chapter 3723 (Ohio Department of Health Radon Licensing Program), done to the state rules in OAC 3701-69; the consensus standard for existing homes is ANSI/AARST SGM-SF-2023. The Ohio Department of Health Radon Licensing Program oversees radon program compliance for Upper Arlington, and Ohio licensure under ORC 3723.02 applies to any contractor performing mitigation work in the state.
