A standard basement or slab radon mitigation system installs in 4-8 hours. Crawl-space systems with encapsulation take 1-2 days. Same- or next-week installs are typical across Greater Cincinnati.
More detail
A typical Cincinnati install day runs 7:30 AM crew arrival, core-drill the slab to create the suction pit by 9:00 AM, run the 4-inch PVC stack by 11:00 AM, mount the inline radon fan and run dedicated 15A wiring by 2:00 PM, install the manometer and cleanup by 4:00 PM. Crawl spaces add a vapor-barrier encapsulation step which extends the work to 1-2 days. Multi-zone homes (more than one foundation type, common in Indian Hill custom builds and Madeira additions) can extend to 1.5 days even on slab. The post-install 48-hour retest does not require homeowner presence; our technician places a continuous radon monitor and returns to retrieve it. Total time from "call placed" to "verified post-mitigation reading below 2.0 pCi/L" is typically 8-11 calendar days. Plan for two scheduling contingencies: outdoor temperatures below 40°F can delay the polyurethane sealing portion of the work (the caulk needs above-freezing cure conditions), and crew availability typically tightens during March-October peak season. Booking 2-3 weeks ahead during peak season is the comfortable lead time; emergency real-estate-driven installs always get prioritized within Cincinnati-area capacity. Our Cincinnati-area crews handle every install in-house with NRPP-credentialed mitigators working to ANSI/AARST MAH-2023 protocols. Free phone consultations include scope-triage and produce a price range within 10 minutes; on-site assessments produce a written fixed-price quote good for 30 days. Our workmanship warranty terms are confirmed in writing before any work begins.
