Radon Levels Around St. Cloud
Zone 1
the EPA radon zone for Stearns County, predicting average indoor levels above 4 pCi/L
Zone 1 is the highest of the three EPA radon potential categories. MDH publishes actual county-by-county test results on its public data portal, and its statewide findings, 2 in 5 tested homes high and an average more than three times the national average, apply to the St. Cloud area with no discount.
Granite Bedrock and Glacial Cover
The St. Cloud area sits on some of the oldest rock in the state, granite formed about 1.7 billion years ago and quarried here for more than a century, under a surface of glacial till and outwash left by the ice sheets. MDH traces radon to the natural decay of uranium in rocks and soil, and igneous bedrock plus the glacial sediments ground from it is precisely where that decay chain operates. The Minnesota Geological Survey maps the glacial deposits blanketing the region.

St. Cloud mixes early-1900s neighborhoods on block and stone basements, wide postwar tracts of ramblers and split-levels, student rentals near St. Cloud State, and newer construction spreading toward Sartell and Sauk Rapids. Anything permitted after June 1, 2009 includes a passive radon rough-in under Minnesota Rules 1303.2400. Mid-century basements are straightforward suction-point installs; split-levels with partial slabs sometimes need the pressure field extended under both levels.
Local Radon Contacts and Test Kits
Stearns County maintains a radon information and testing page for residents, and the MDH Local Radon Contacts directory lists current programs for every county in the region.
What Does Radon Mitigation Cost in St. Cloud?
The Minnesota Department of Health reports a typical installed range of $1,500 to $3,000 statewide. Foundation type, home size, and routing decide where a St. Cloud home lands. The cost guide breaks down every factor with primary-source numbers.
Verify Your Contractor's Minnesota Radon License
Before you hire anyone for radon work in St. Cloud, check their license. The Minnesota Radon Licensing Act, Minnesota Statutes section 144.4961, requires anyone who performs radon testing, mitigation, or laboratory analysis for compensation to be licensed by the Minnesota Department of Health, and every mitigation system installed under the law must carry an MDH system tag. A licensed professional expects the question. Three things to ask before you sign:
- Can I see your current MDH radon license, and is the company licensed too?
- Will the installed system carry the MDH system tag required under the licensing law?
- Will I get a written, itemized estimate and a follow-up radon test that confirms the system works?
St. Cloud Radon Questions
Does St. Cloud granite mean higher radon?
Granite is igneous rock, and MDH attributes Minnesota radon to uranium decaying naturally in rocks and soil. Stearns County carries the EPA Zone 1 rating, predicting average indoor levels above the action level. Geology sets the odds; only a test of your own house settles it.
I own a rental near St. Cloud State. Should it be tested for radon?
Yes. MDH recommends testing the lowest lived-in level of any home, and basement bedrooms in rentals are exactly the exposure case that matters most. Testing is inexpensive, and if mitigation is needed it is a licensed contractor job with typical statewide costs of $1,500 to $3,000 per MDH.
My newer home toward Sartell has a radon pipe in the closet. Am I covered?
That pipe is the passive system Minnesota Rules 1303.2400 requires in homes permitted after June 1, 2009. It helps, but it runs on natural stack effect alone, and MDH still recommends testing. If your result is high, a licensed contractor adds a fan in the attic to convert it to an active system.
