Radon mitigation quotes in St. Paul
St. Paul is the older of the Twin Cities, with grand historic districts on Summit Avenue and the surrounding hills, dense working neighborhoods on the east side and West Seventh, and river-bluff housing above the Mississippi.
Historic foundations are where mitigation design earns its keep. St. Paul homeowners hire independent, MDH-licensed contractors.
St. Paul and Ramsey County
St. Paul is the Ramsey County seat, and its residential ZIP codes route through our Ramsey territory, which also covers Roseville, Maplewood, Shoreview, and the city’s north side. EPA places Ramsey County in Zone 1. Minnesota licenses radon professionals through the Department of Health.
If the result surfaced in a transaction
Minnesota’s Radon Awareness Act requires sellers to disclose known radon information and provide the MDH publication before a purchase agreement is signed. Nothing requires testing or mitigation. In the historic districts, how a system will be routed is a legitimate negotiation point alongside whether one is installed.
Those duties are set in Minnesota, not in Ramsey County — Minnesota radon disclosure rules has the statute and the agency behind it, including what a seller must hand over and what stays negotiable.
The housing you’re mitigating
The historic districts bring brick, stone, and early block foundations with a century of additions, full basements often finished, and porch crawl spaces. Bluff-side homes may have multiple slab elevations. East-side and newer stock is conventional block or poured construction with more straightforward routing.
Radon results do not stop at a municipal boundary, and neither do the contractors quoting here: the same Ramsey County soil and the same building era run through Minneapolis, Woodbury and Eagan, which is why a reading in one of them is worth knowing about when you are interpreting yours. For the wider picture, radon across Minneapolis–St. Paul sets out how results vary between communities here, and what a system costs in Minneapolis–St. Paul covers the price drivers before you start collecting numbers.

St. Paul questions, answered straight
Can a Summit-area historic home be mitigated discreetly?
Yes, and you should require it. Contractors route pipe on rear or side elevations, through the garage, or up an interior chase to the roof precisely to preserve character-defining elevations. Ask for photos of previous historic-home work when comparing bidders.
Our house has a stone foundation and a dirt-floor section. Feasible?
Yes, with both conditions in the design. Exposed soil gets a sealed durable membrane with suction drawn beneath it; the masonry gets careful sealing, with suction points chosen after measuring how air moves under the floor. Confirm the quote names the dirt-floor area.
Does Minnesota require the seller to fix an elevated result?
No. The Radon Awareness Act is a disclosure law — sellers share what they know and provide the MDH publication. Whether anyone mitigates, and who pays, is negotiated like any other inspection finding.
What documentation should we keep once the system is in?
The installer's Minnesota Department of Health license number as it appears on the contract, the scope or diagram showing suction-point locations, the post-mitigation test report with its date, and the fan model with warranty terms. The Minnesota Radon Awareness Act requires sellers to disclose known radon information before a purchase agreement is signed — in a St. Paul sale, that folder makes the disclosure a one-page answer with a verified number.
Is the fan a permanent fixture or a part that wears out?
These are always-on motors. Manufacturers back them for a set number of years, after which they are maintenance parts rather than fixtures. Replacement is a swap on the existing pipe run — exactly why standards keep fans in a garage, attic, or exterior location instead of finished space. Before signing in St. Paul, ask who administers a warranty claim and whether the labour to change the fan is included or billed as a separate visit.
