Mold removal in Green Bay, done right the first time.
Two rivers, a bay, 69% average humidity, and a housing stock that mostly predates modern waterproofing — Green Bay's mold problem is real. We've been clearing it since 2010. IICRC-certified crew. Written clearance on every job.
Four reasons Green Bay basements keep growing mold.
This isn't a Wisconsin-wide problem. It's specific to where Green Bay sits — two rivers, a bay, and housing built before anyone worried about vapor barriers.
-
01
River confluence The Fox and East Rivers both flood into residential blocks. The 2019 East River event condemned 37 homes, and thousands more took on water in basements that never fully dried.
-
02
69% average humidity Higher than Milwaukee or Madison. Enough to feed mold in crawl spaces and unvented attics year-round, not just in summer.
-
03
Freeze-thaw foundation damage Every spring, water finds hairline cracks that widened over winter. Most of these go unnoticed until mold appears inside.
-
04
Median home age of 51 years Pre-1970 builds rarely have modern vapor barriers, sump systems, or sealed rim joists. Moisture has decades of head start.
Six services. One team. All done in Green Bay.
No subcontractors. No out-of-state crews. Every job is done by the same IICRC-certified technicians who live and work in Brown County.
Find mold before you see it
Plaster walls hide mold. We use thermal imaging and moisture meters to see through them, then lab-test samples to confirm the species before we touch anything.
- Thermal imaging
- Air & surface sampling
- Lab species ID
- Source tracing
Remove mold the right way
Following IICRC S520. Containment, HEPA scrubbers, safe material removal, and antimicrobial treatment. Third-party clearance test before we leave.
- Negative-air containment
- HEPA scrubbing
- EPA-registered treatment
- Clearance test
Black mold, handled properly
Stachybotrys releases mycotoxins when disturbed. Different protocol than standard mold — full containment, sealed disposal, lab verification.
- Species confirmation first
- Full containment
- Sealed disposal
- Lab verification
Basements & crawl spaces
Where most Green Bay work starts. We remove mold from joists and subflooring, then fix the water source so the next rain isn't a repeat.
- Joist treatment
- Subfloor work
- Vapor barriers
- Drainage plans
Attic mold from ice dams
Ice dams are the #1 cause of attic mold in Green Bay. Water backs up under shingles and the mold shows up months later. We treat the wood and fix ventilation.
- Sheathing remediation
- Truss treatment
- Ventilation work
- Insulation guidance
Water damage restoration
Every hour water sits, mold risk climbs. We extract, dry, and monitor until moisture readings hit dry standard. Insurance billed directly.

Recent Green Bay jobs. Real quotes.
Third company we called. First one that actually tested the air before quoting. Turned out the mold was in two rooms we didn't even know about.
Called Tuesday about water in the crawl space from the spring melt. They were out the same afternoon, dried it, and found mold on three joists. Whole thing handled in four days.
Didn't try to sell me a full remediation for a small patch. Gave me an honest assessment, tested it, and it came back as surface mildew. Saved me thousands.

Why is mold so common in Green Bay basements?
The Fox River, East River, and the bay keep humidity high (69% average). Add spring snowmelt, freeze-thaw foundation cracks, and a housing stock that mostly predates vapor barriers, and basements stay damp. The 2019 East River flood made it worse for thousands of homes.
