About Sioux Falls Radon Pros

This is a radon service for a city that sits on some of the worst radon geology in the country. The pitch is short. You see real prices before you commit, and a retest proves the work after.

Why This Service Exists Here

Minnehaha and Lincoln counties are both EPA Zone 1, the highest radon designation there is. Tested homes in Minnehaha County average 6.5 pCi/L, well above the 4.0 federal action level. Most homes across the Sioux Empire have never been tested at all. That gap between the geology and the testing rate is the entire reason this service exists.

How We Work

Three habits, visible on every page of this site:

• Prices in the open. Typical install and testing costs are published here, sourced from national cost guides and the state's own figures. Most contractors in this market don't publish prices. We'd rather you walk in knowing what fair looks like.
• EPA protocol, not improvisation. Tests run 48 hours minimum under closed-house conditions. Installs end with a verification retest, on the EPA's timeline, and you keep the paperwork. Details live on the testing page and in our install guide.
• Claims you can check. The radon facts on this site cite the EPA and South Dakota DANR. If a number here can't be traced to a source, it doesn't get published.

What We Are and Aren't

We're a local operation that connects southeastern South Dakota property owners with licensed, insured pros for testing and mitigation, as the footer on every page discloses. No inflated backstory, no stock-photo crew. Judge us the way we'd judge a quote: on what's written down and what the retest says.
