Plymouth Neighborhoods We Serve

Plymouth sits in Hennepin 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 Plymouth, 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.

Plymouth Real Estate Radon FAQ

Closing-Timeline Questions Plymouth Buyers + Agents Ask

Frequently Asked Questions

Home inspection radon test failed on my Plymouth purchase — what now?
If your buyer's inspection radon test returned at or above 4.0 pCi/L, you have a routine Plymouth 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 Plymouth radon contingencies fit comfortably inside this window.
How quickly can radon mitigation happen before closing in Plymouth?
Plymouth 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 Plymouth home sale?
Roughly 60% of Plymouth 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 Plymouth, MN?
Plymouth single-family radon mitigation typically runs $1200-$2500. Standard active sub-slab depressurization (ASD) is the most common system type (~85% of Plymouth 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 Plymouth have higher-than-average radon levels?
Plymouth (Hennepin County) averages 4.4 pCi/L indoor radon — that's 1.1x the EPA action level of 4 pCi/L. Approximately 40% of Plymouth 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 Plymouth listing is not unusual — it should be expected on a meaningful share of transactions.
Will an FHA / VA / USDA lender accept Plymouth 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 Plymouth radon mitigation happen during the standard 10-day inspection contingency window?
Yes — the 7-14 day mitigation workflow fits inside most standard Plymouth 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 Plymouth sellers pre-test for radon before listing?
Strongly recommended — especially in Hennepin County where county average is 4.4 pCi/L. Pre-listing radon testing lets Plymouth 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.
