Frequently asked questions
Is radon really a problem in Iowa City?
Yes — measurably. Every one of Iowa's 99 counties is EPA Zone 1, the highest-risk designation, and user-submitted Iowa test results average about 10.15 pCi/L, roughly 2.5 times the EPA's 4.0 pCi/L action level. Iowa City takes it seriously enough that it is one of only about 11 jurisdictions in the country to require radon-resistant new construction by code.
How much does a radon mitigation system cost in Johnson County?
Most of our installs run $800 to $2,000, flat-quoted before any work starts. Simple exterior systems on newer Coralville or North Liberty homes sit at the low end; pre-1950 Northside stone foundations that need extra sealing or a second suction point sit at the high end.
How long does installation take?
One day. We install the suction point, run the vent stack, mount and wire the fan, and seal entry points in a single visit, then leave a post-mitigation test running to verify the result.
Do you serve towns outside Iowa City?
Yes — Coralville, North Liberty, Tiffin, Solon, University Heights and the surrounding Johnson County area. We run rural routes to Solon and Lake Macbride acreages on a set schedule so drive time never inflates your quote.
