Green Bay Neighborhoods We Serve

Green Bay sits at the southern end of the Fox River valley in Brown County, classified EPA Zone 2 (moderate predicted radon). Northeastern Wisconsin's mix of glacial-till deposits and underlying Niagaran dolomite (which extends north into Door County's known elevated-radon peninsula) drives variable but routinely-elevated radon readings in basement-construction homes.

Green Bay Real Estate Radon FAQ

Closing-Timeline Questions Green Bay Buyers + Agents Ask

Frequently Asked Questions

Home inspection radon test failed on my Green Bay purchase — what now?
If your buyer's inspection radon test returned at or above 4.0 pCi/L, you have a routine Green Bay 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 Green Bay radon contingencies fit comfortably inside this window.
How quickly can radon mitigation happen before closing in Green Bay?
Green Bay 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 Green Bay home sale?
Roughly 60% of Green Bay 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 Wisconsin 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 Green Bay, WI?
Green Bay single-family radon mitigation typically runs $1000-$2500. Standard active sub-slab depressurization (ASD) is the most common system type (~85% of Green Bay 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 Green Bay have higher-than-average radon levels?
Green Bay (Brown County) averages 5.5 pCi/L indoor radon — that's 1.4x the EPA action level of 4 pCi/L. Approximately null% of Green Bay homes test elevated. Green Bay's cold winters (Lake Michigan-modified) drive sustained stack-effect-driven radon influx during closed-house conditions, typically late fall through early spring. This means a failed-inspection radon test on a Green Bay listing is not unusual — it should be expected on a meaningful share of transactions.
Will an FHA / VA / USDA lender accept Green Bay radon mitigation documentation?
Yes. Our standard real-estate-transaction documentation package includes (1) the original inspection radon result, (2) the partner contractor's NRPP + WI DHS 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 Green Bay radon mitigation happen during the standard 10-day inspection contingency window?
Yes — the 7-14 day mitigation workflow fits inside most standard Green Bay 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 Wisconsin extension language.
Should Green Bay sellers pre-test for radon before listing?
Strongly recommended — especially in Brown County where county average is 5.5 pCi/L. Pre-listing radon testing lets Green Bay 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.
