System Repair & Reactivation in Hyde Park, OH

System Repair & Reactivation in Hyde Park 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.

Hyde Park's owner-occupied stock skews heavily 1910-1940 with lath-and-plaster walls, full basements with stone or early-concrete foundations, and steep-pitched attics with rafter cavities open to the roof deck. Wall cavities are frequently empty or hold settled fiberglass batts from a 1970s-80s retrofit. Hyde Park 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.

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 Hyde Park, and Ohio licensure under ORC 3723.02 applies to any contractor performing mitigation work in the state.
