Radon Levels Around St. Paul
Zone 1
the EPA radon zone for Ramsey County, predicting average indoor levels above 4 pCi/L
Zone 1 is the highest EPA radon potential category, and MDH's statewide findings apply across St. Paul's neighborhoods: 2 in 5 tested homes high, average levels more than triple the national average. County-by-county test results are published on the MDH data portal, and Ramsey County's discounted kit program removes the cost excuse for finding out.
Glacial Deposits Over the East Metro
St. Paul is built on the same glacial blanket as the rest of the metro, till and outwash mapped by the Minnesota Geological Survey, over the sandstone and limestone bedrock exposed in the river bluffs below downtown and along Shepard Road. MDH ties radon to uranium decaying naturally in rocks and soil, and the glacial deposits deliver that source under every neighborhood from Highland to the East Side. House-to-house variation, not neighborhood lines, decides individual readings.

St. Paul's stock skews old: Victorian and early-1900s homes on stone and limestone-block foundations around Summit Hill, Frogtown, and Dayton's Bluff, streetcar-era bungalows across the city, postwar ramblers toward Highland and Como edges, and newer infill. Old foundations mean more sealing work and occasionally creative vent routing on historic blocks, both routine for licensed contractors. Ground-contact condo and duplex units carry the exposure in multifamily buildings.

What Does Radon Mitigation Cost in St. Paul?
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. Paul 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. Paul, 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. Paul Radon Questions
Where can I get a cheap radon test kit in St. Paul?
St. Paul-Ramsey County Public Health sells discounted short-term test kits to Ramsey County residents; details are on the county radon page and in the MDH Local Radon Contacts directory. Run the test in the lowest lived-in level during the heating season for the most meaningful result.
My St. Paul house is from the 1890s with a stone foundation. Can it be fixed?
Yes. Stone foundations are standard work for licensed mitigation contractors: seal what is accessible, pull from beneath the basement slab or a sump, and route the discharge above the roofline. The post-installation test verifies the result regardless of the house's age.
Is radon worse on the East Side or in Highland?
Neither in any predictable way. The glacial deposits under St. Paul carry the radon source everywhere, and MDH data shows individual results vary far more within neighborhoods than between them. The county's discounted kits make testing your specific house the rational move.
Does radon disclosure apply when I sell my St. Paul home?
Yes. The Minnesota Radon Awareness Act requires sellers to disclose radon records in writing and deliver the MDH radon publication before a purchase agreement is signed. Metro buyers routinely test during inspections, so many St. Paul sellers test first and fix on their own schedule.
