University Heights homeowners looking into radon mitigation can start with a short-term kit from Johnson County.
Before you test or fix in University Heights
Johnson County Public Health notes that Iowa has the largest share of homes above EPA's 4 pCi/L action level, 71.6% [1]. The county lists three uses for its short-term kits: a first test, a second test after a high result, and a check after a system is installed [1].
Where can University Heights residents buy a radon kit?
Johnson County Public Health sells short-term kits for $12 and long-term kits for $30 in the office, and mails them for $3 more. Call 319-356-6040 [1].
How often should University Heights homes test?
Johnson County Public Health suggests testing every 2 years, even with a mitigation system in place, and again after any major renovation to the house [1].
Iowa's statewide rules for testers and mitigation specialists are on how it works. To read up first, try radon testing, how a system works or fan replacement. City pages: Cedar Rapids and Iowa City. Every other town is listed on all service areas.

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.
