System Repair & Reactivation in Upper Arlington, OH

System Repair & Reactivation in Upper Arlington involves fan replacement, manometer recalibration, slab-penetration reseal, and discharge-stack rework as needed, working on an existing mitigation system that has lost performance, made noise, or failed a post-install retest. The service is the right scope when an existing system is 5+ years old, the manometer reads zero or near-zero, or a recent retest came back above 4.0 pCi/L despite an existing system.

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.

System repairs in Franklin County are most common on the older, aged-slab installs found in Columbus's established neighborhoods, where original penetration seals have had more years to degrade than the systems installed in Dublin and Hilliard's newer, more uniform poured-basement subdivisions.

Repairs must restore the system to ANSI/AARST CCAH-2020-0523 compliance; the manometer must show continuous negative pressure and a post-repair retest is required. 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.
