Cedar RapidsIowa City

We take radon mitigation and testing requests from 24 towns around Cedar Rapids and Iowa City. Each town page has its own notes. Some cover a city building code or rental rule, and others cover the county health office where you can get a kit.

Start with a test if you haven't had one. Iowa HHS lists free kits by county, one per household while supplies last [1]. If your result is 4 pCi/L or higher, EPA calls for a follow-up test before you decide on a fix [2]. Then use your town page and the radon mitigation cost guide to plan the next step.

We're a referral service, not a contractor. We send mitigation requests only to contractors on Iowa HHS's current credentialed list and testing requests only to state-certified radon measurement specialists, but we don't otherwise vet them, a referral is not an endorsement, and independent contractors may pay us for referrals.
