Why Sioux City homeowners can't ignore radon

Iowa leads the nation with 71.6% of homes above the EPA action level of 4.0 pCi/L, and Woodbury County sits in the highest-risk EPA Radon Zone 1.

The soils beneath Siouxland are exactly the kind that push radon gas up through basement floors, sump pits, and foundation cracks. The good news: radon is completely fixable. A properly designed sub-slab depressurization system vents the gas safely above your roofline before it ever enters your living space.

Frequently asked questions

Is radon really a problem in Sioux City?

Iowa leads the nation with 71.6% of homes above the EPA action level of 4.0 pCi/L, and Woodbury County sits in the highest-risk EPA Radon Zone 1. Radon is the second-leading cause of lung cancer in the U.S. after smoking, and you can't see or smell it.

How much does radon mitigation cost?

Most systems run $800โ€“$2,000, with a standard basement sub-slab system typically $1,000โ€“$1,500. We quote a flat price up front.

How long does installation take?

Most residential systems are installed in a single day, followed by a post-installation test to confirm your levels dropped below the action level.

Will it get me below 4.0 pCi/L?

In the large majority of homes, yes โ€” and we prove it in writing. If a system we install doesn't hit the target, we make it right. That's what the 5-year warranty is for.
