De Pere's Fox River mold problem, solved by a local team.
From the historic riverfront blocks near Voyageur Park to the newer subdivisions on the west side, De Pere homes have specific moisture problems — original clay plumbing, a rising water table, and sump systems that get tested every storm. We've been handling them since 2011. IICRC-certified crew. Written clearance on every job.
Four reasons De Pere homes keep growing mold.
This isn't a general Brown County problem. It's specific to where De Pere sits — on the Fox River, over a high water table, on top of housing stock that mostly predates modern plumbing codes.
-
01
Fox River water table De Pere sits directly on the Fox River, and the water table rises with it every spring. Homes within a few blocks of the riverfront — especially around Voyageur Park and the historic downtown — deal with ground water pushing up through foundations that homes further inland never see.
-
02
Original cast iron & clay plumbing Many pre-1960s De Pere homes still run on original cast iron drain lines and clay lateral sewer pipes. These crack, sag, and root-intrude decades before modern PEX or PVC would. A slow leak behind a wall is often the first sign — usually after mold has already taken hold.
-
03
Sump pump failures during storms De Pere's storm season is when sump pumps get tested. A power flicker during a heavy rain event can leave a finished basement under two inches of water before the homeowner wakes up. It's one of the most common emergency calls we get from the city.
-
04
West Side lot grading issues Newer subdivisions on the west side were graded to code — but a lot of them were graded to minimum code. Undersized gutters and short downspouts push runoff straight toward the foundation instead of away from it. Water finds the path of least resistance, and it's usually your basement.
Six services. One crew. All done in De Pere.
No subcontractors. No out-of-town crews. Every job is done by the same IICRC-certified technicians who work Brown County every day.
Test moisture before treating mold
De Pere's pre-1960s housing hides water inside wall cavities, under original hardwood, and behind finished basement walls. Thermal imaging and moisture meters find it. Lab tests confirm the species.
- Thermal imaging
- Air & surface sampling
- Lab species ID
- Source tracing
Remove mold to IICRC S520
Every De Pere remediation follows IICRC S520: physical containment, negative air pressure, HEPA scrubbing, and EPA-registered antimicrobial treatment. A third-party lab verifies clearance.
- Negative-air containment
- HEPA scrubbing
- EPA-registered treatment
- Clearance test
Stachybotrys needs its own protocol
Black mold releases mycotoxins when disturbed. Full containment, sealed disposal, HEPA filtration throughout, and post-remediation lab verification. Riverfront De Pere homes see more of this than most of Brown County.
- Species confirmation first
- Full containment
- Sealed disposal
- Lab verification
Basements & crawl spaces
Between the Fox River water table and undersized sump systems, this is where most De Pere work happens. We remove mold from joists and subflooring, then address the water source — not just the symptom.
- Joist treatment
- Subfloor work
- Vapor barriers
- Crawl encapsulation
Attic mold from ice dams
De Pere winters build ice dams at the roofline, forcing melting snow back under the shingles. Water soaks the sheathing and insulation, and mold shows up months later on the ceiling below. We treat the wood and fix the ventilation that caused it.
- Sheathing remediation
- Truss treatment
- Ventilation work
- Insulation guidance
Water damage restoration
Burst pipes, sump pump failures, appliance leaks, and storm flooding. Our De Pere crew is on call 24/7 and typically on-site in under an hour. Direct insurance billing handled.
- Emergency extraction
- Structural drying
- Moisture monitoring
- Insurance billing
