Warranty terms are set by your lead technician and confirmed in writing before work begins. Most Cincinnati mitigators offer a multi-year workmanship warranty on the install plus a manufacturer warranty on the fan. Post-install retest at 48 hours and 12 months is standard across our Cincinnati team.

Three components carry separate warranty windows. The install workmanship warranty (sealing, routing, mounting, electrical) is typically 1-5 years depending on our technician. The fan itself is covered by manufacturer warranty: Radonaway RP145 carries a 5-year manufacturer warranty; Festa branded fans carry 10 years. The post-install verification testing (the 48-hour retest plus 12-month retest) is part of the original quote and is performed at no additional cost. If the post-mitigation reading exceeds 2.0 pCi/L on the verification test, our technician returns to troubleshoot at no charge; typical fixes are additional sealing or fan upsizing. Always get warranty terms in writing before signing the quote; verbal "lifetime guarantees" are unenforceable and a red flag. Our workmanship warranty norms: 5 years on routing and sealing, 10 years on the fan (matching manufacturer), lifetime on the install paperwork. Some installers offer transferable warranties (carries to next homeowner at sale); others do not. Confirm transferability before signing if the homeowner plans to sell within the warranty window; a transferable warranty adds modest resale value.
