Most Cincinnati homes pay $1,200-$2,400 for a complete radon mitigation system installed. Crawl-space homes run $1,800-$3,500 due to vapor-barrier work. Initial 48-hour testing is $150-$300. Free phone quotes available.
More detail
Pricing depends on foundation type (slab vs. basement vs. crawl space), system routing (interior vs. exterior), fan size required, sealing scope, and the post-mitigation pCi/L target. The cheap end ($1,200-$1,500) covers newer slab-on-grade homes with exterior routing on an unobstructed wall. The middle ($1,500-$2,000) covers older basements with some sealing required and interior chase routing. The high end ($2,000-$2,400) covers stone or block basements requiring substantial mortar-joint sealing or multi-zone homes needing two suction points. Crawl-space mitigation is its own pricing tier ($1,800-$3,500) because of the vapor-barrier and encapsulation work. Cincinnati pricing has held steady across credentialed mitigators for 3-5 years; quotes rarely vary more than 10-15% on the same scope, and any quote varying more is a flag to get a second opinion. Free phone consultations include foundation-type triage and produce a price range within 10 minutes. Watch for two pricing red flags: a "starting at" quote without on-site assessment (means the actual quote will be higher) and any contractor unwilling to put the price in writing before work begins. Both indicate scope creep or change-order pressure during install. The Cincinnati-area standard is a written, fixed quote good for 30 days, signed before any work happens.
