St. Paul Neighborhoods We Serve

St. Paul sits in Ramsey County in Minnesota's glacial-till lowlands. Minnesota's statewide indoor radon average is 4.4 pCi/L — well above the EPA action level of 4.0 pCi/L and the U.S. average of 1.3 pCi/L. With glacial-till lowlands geology and full-basement housing common in St. Paul, EPA and Minnesota health officials recommend every home be tested. If your test is 4.0 pCi/L or higher, mitigation is recommended; levels between 2 and 4 pCi/L are also worth addressing given Minnesota's elevated background radon.

Closing-Timeline Questions St. Paul Buyers + Agents Ask

Frequently Asked Questions

Home inspection radon test failed on my St. Paul purchase — what now?
If your buyer's inspection radon test returned at or above 4.0 pCi/L, you have a routine St. Paul transaction decision. The most common path: seller-paid mitigation completed before closing. Quote arrives within 2 hours of forwarding us the inspection report. Install in 4-8 hours of on-site work. Post-mitigation verification within 48-96 hours. Closing documentation package within 11 days. Most St. Paul radon contingencies fit comfortably inside this window.
How quickly can radon mitigation happen before closing in St. Paul?
St. Paul real-estate-transaction radon mitigation timeline runs Day 1-11: quote (Day 1) → buyer/seller agreement (Day 1-3) → priority install (Day 3-7) → 48-96 hour post-mitigation verification (Day 8-10) → lender-acceptable documentation package (Day 11). Real-estate-transaction jobs jump our standard queue; no rush premium.
Who typically pays for radon mitigation in a St. Paul home sale?
Roughly 60% of St. Paul real-estate-transaction radon mitigations are seller-paid (seller fixes before close), 30% are negotiated as a closing credit (buyer takes cash at close), 10% are buyer-paid. The Minnesota Real Estate Purchase Agreement does not mandate which party pays — your real estate agent negotiates with the other side. The seller-paid + repair-before-close path is preferred by FHA, USDA, and VA underwriters.
What does radon mitigation cost in St. Paul, MN?
St. Paul single-family radon mitigation typically runs $1200-$2500. Standard active sub-slab depressurization (ASD) is the most common system type (~85% of St. Paul installs). We do NOT charge a rush premium for closing-timeline work; real-estate-transaction jobs price at the same range as standard installs.
Does St. Paul have higher-than-average radon levels?
St. Paul (Ramsey County) averages 4.4 pCi/L indoor radon — that's 1.1x the EPA action level of 4 pCi/L. Approximately 40% of St. Paul homes test elevated. Cold Minnesota winters intensify the stack effect — heated indoor air rising creates negative pressure that pulls radon-laden soil gas into basements. Winter radon readings commonly run 30–50% higher than summer. This means a failed-inspection radon test on a St. Paul listing is not unusual — it should be expected on a meaningful share of transactions.
Will an FHA / VA / USDA lender accept St. Paul radon mitigation documentation?
Yes. Our standard real-estate-transaction documentation package includes (1) the original inspection radon result, (2) the partner contractor's NRPP + MDH certifications, (3) the post-mitigation verification test result confirming the home is below 4 pCi/L, and (4) install warranty (5-year fan, lifetime piping). This package is accepted by FHA, USDA, VA, and all major conventional lenders without further documentation requests.
Can St. Paul radon mitigation happen during the standard 10-day inspection contingency window?
Yes — the 7-14 day mitigation workflow fits inside most standard St. Paul 10-14 day inspection contingency windows. If the contingency was written tighter (5-7 days), a contingency-extension agreement between buyer and seller is typically the cleanest path; your real estate agent can advise on standard Minnesota extension language.
Should St. Paul sellers pre-test for radon before listing?
Strongly recommended — especially in Ramsey County where county average is 4.4 pCi/L. Pre-listing radon testing lets St. Paul sellers (1) surface elevated readings before going under contract, (2) mitigate proactively at standard pricing instead of under buyer-side closing pressure, (3) market the home with a verified-mitigated radon result as a transaction advantage. Listings with documented pre-mitigation typically close faster and at full price.
