Radon mitigation in Hills starts with picking the right test, short-term or long-term.
Hills rules and resources
Johnson County Public Health suggests a long-term kit when you want your radon level as an average over a longer period [1]. Iowa HHS says Johnson County households can order a free kit through the American Lung Association, though some are redirected to Healthy Hometowns [2].
Should Hills homeowners use a short- or long-term kit?
Johnson County suggests a long-term kit, 3 to 12 months, for an average over a longer period, and a short-term kit, 3 to 7 days, for a first test or a quick recheck [1].
Where can Hills residents buy a kit?
Johnson County Public Health sells both kinds. Call 319-356-6040, and pick the kit up at the office or have it mailed for $3 more [1].
Depending on your result, you may want radon testing, radon in a home sale or how a system works. We gather the state rules for testers and mitigators in one place, how it works. Also covered: Cedar Rapids and Iowa City, plus all service areas.
Have a number from a test? Send a request.
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.
