Iowa City Radon exists for one reason: this corner of Iowa has some of the highest indoor radon levels in the country, and every family deserves to know what's in the air they breathe at home. We provide certified radon testing and mitigation across Iowa City, Coralville, North Liberty, and the rest of Johnson County.
Radon work is all we do. Not a side service bolted onto a home inspection business, not one line on a general contractor's menu — testing, mitigation, repair, and compliance, every day, in the same soil and the same housing stock.
Why We Focus on Radon
Roughly 7 in 10 Iowa homes test at or above the EPA action level of 4.0 pCi/L, and Johnson County sits in EPA Zone 1 — the highest radon potential classification there is. Radon is the second-leading cause of lung cancer in the United States and the leading cause among people who have never smoked.
Those numbers are why we treat radon as a health service, not a checkbox. A test tells you the truth about your home. A properly built mitigation system fixes it — usually in a single day, verified with a follow-up test.
Certified, Local, and Accountable
Radon professionals in Iowa are required to be certified through the state radon program, and we work to those standards on every job — calibrated continuous monitors, closed-house test protocols, and mitigation systems built to bring homes under 2.0 pCi/L.
Because we're local, we know the quirks of this market: the pre-war basements near downtown and the Northside, the sump-pit systems common across Coralville, the new builds in Tiffin and North Liberty with passive rough-ins that still test high, and the rental stock around the University of Iowa that falls under the city's radon ordinance.
Who We Work With
Homeowners who want a straight answer and a fixed price. Buyers and sellers on inspection-period deadlines who need a 48-hour test scheduled yesterday. Landlords keeping single-family and duplex rentals compliant with Iowa City's rental radon ordinance. Property managers and business owners responsible for larger buildings.
Whoever you are, the experience is the same: a real person on the phone, a clear scope and price before any work starts, and a written result you can rely on — whether that's for your family, your closing, or your rental permit file.
How We Work
Every job starts with a conversation and ends with a verified number. If you need a test, we schedule quickly, run it by the book, and walk you through what the result means. If you need mitigation, we design the system for your foundation — not a one-size-fits-all install — and we retest after installation to prove it worked.
No scare tactics, no padded quotes. Radon is a solvable problem, and solving it well is the whole business.
