Woodbury County sits in EPA Zone 1 — the highest radon potential in the country. If your home tested at 4.0 pCi/L or above, a mitigation system can bring it down dramatically, usually in a single day's work.
Straight answers, free estimates, and a retest after installation so you know it worked.
Radon is measured in picocuries per liter (pCi/L)
How it works
Call or send the form with your radon test result — or ask us to test first. We'll talk through what your level means for your home and family, no pressure.
We design a sub-slab depressurization system for your foundation type — basement, slab, or crawlspace — and install it in about a day, sealed and labeled.
After 24 hours of runtime we retest. You get the before-and-after numbers in writing, plus what to expect from your system long-term.
The fix
Services
Custom-designed sub-slab, sump, and crawlspace systems for Siouxland's basements — installed in about a day and verified with a retest.
Mitigation systemsShort-term tests, long-term tests, and real-estate transaction testing on the 48-hour protocol — with results you can act on.
Testing optionsRadon-resistant rough-ins and passive-to-active conversions for new builds in Dakota Dunes, Sergeant Bluff, and beyond.
New constructionLocal, on purpose
The glacial soils under the Missouri River valley are rich in uranium-bearing till. As it breaks down it releases radon gas, which rises through the soil and gets pulled into houses by the small vacuum every heated home creates — strongest in winter, when Sioux City homes are sealed tight for months. Add the region's older housing stock — deep basements, sump pits, stone or block foundations — and you get some of the most radon-prone homes in America. That's not a scare tactic; it's the reason Iowa leads the nation in average indoor radon.
Quick answers
It's real. The EPA attributes about 21,000 U.S. lung cancer deaths a year to radon exposure — it's the leading cause of lung cancer in people who've never smoked. The risk builds with years of exposure, which is why long-term fixes matter more than panic.
Most single-family installs in the Siouxland area fall in the $1,200–$1,800 range, depending on foundation type and how the vent has to route. You'll get a firm number in your quote — not a surprise after the work.
Unfortunately not — radon varies house to house, even next door, because it depends on the soil directly under your foundation and how your specific house breathes. Testing your own home is the only way to know.
Real-estate deadlines are our specialty. Transaction testing runs on a 48-hour protocol, and most mitigation installs happen within days, not weeks. Tell us your closing date and we'll work backwards from it.
