Radon Testing in Upper Arlington, OH

Radon Testing in Upper Arlington involves short-term (2-7 day) charcoal canister or continuous radon monitor placement on the lowest occupied level, working on the lowest lived-in level of the home where occupants spend more than 4 hours per day. The service is the first step for any home that has not been tested in the last 2 years, for any home being sold, and for any home after a significant foundation, basement, or HVAC modification.

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 testing applies across all of EPA Zone 1, but the aged, cracked slabs in Columbus's older neighborhoods are more likely to show an elevated short-term reading than the newer, more uniform poured basements in Dublin and Hilliard, which is why a retest after any slab or foundation repair is standard practice here.

ANSI/AARST MAH-2023 establishes the residential measurement protocol. Closed-house conditions must be maintained throughout short-term testing. 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.
