The EPA action level is 4.0 pCi/L — at or above that level, mitigation is recommended. The EPA also recommends considering mitigation between 2.0 and 4.0 pCi/L. There is no safe level of radon; risk is cumulative with exposure.

Most Iowa City radon mitigation installs are completed in a single day, typically 4 to 8 hours. The post-install retest takes another 48 hours but doesn't require any disruption to your household.

A correctly installed system lasts 15 to 20+ years. The fan typically lasts 7 to 15 years and is the most likely component to fail; most fans carry a 5-year manufacturer warranty. The pipework and seals are essentially permanent.

Iowa law does not require mitigation before sale, but it does require disclosure. In practice, most buyers in Iowa City request mitigation as a condition of closing when test results are above 4.0 pCi/L. Sellers usually pay or credit at closing.
Read full answer →Where does the radon fan get installed?
Per EPA guidelines, the fan must be installed in an unconditioned space — typically the attic or mounted on an exterior wall. Fans are never installed inside finished living space, in basements, or in crawlspaces.
Read full answer →How loud is a radon mitigation system?
Modern radon fans are very quiet — typically 30 to 45 decibels at the fan, which is quieter than a refrigerator. Inside the home, you usually can't hear it at all unless you're directly under the attic-mounted fan.

Iowa requires radon mitigation specialists to be IDPH-certified, but most Iowa City jurisdictions do not require a separate building permit for installation. We handle any required notifications as part of the install.
Read full answer →Is radon especially dangerous for children?
Yes. Children breathe more air per pound of body weight than adults, their lung tissue is still developing, and their cumulative lifetime exposure is longer. The EPA emphasizes mitigation in homes with children even at moderate elevation.
