After inspection, you receive a complete written itemized estimate for your Mayville project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.

Toxigenic mold species — particularly Stachybotrys — appear in Mayville properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Mayville black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Mayville property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Remediation removes the active colony. Prevention keeps it from coming back — which in Mayville's climate requires addressing the moisture source directly. Every Koppers Waterproofing project in Mayville includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Mayville customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

We were buying a home in Mayville and mold showed up on the inspection report two days before closing. I called Koppers Waterproofing in a panic. They came out the next morning, knocked it out in 48 hours, and we had the clearance report in time for the lender. Deal closed. I've already recommended them to two friends in Mayville.
I manage commercial properties in Mayville and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Mayville property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Mayville commercial remediation now.
Called Koppers Waterproofing for a Mayville crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost. Should have scheduled an inspection sooner.

Signs that warrant a professional Basement Waterproofing inspection in your Mayville property: visible dark spotting on walls, ceilings, or floors; persistent musty odor in bathrooms, basements, or after water events; allergy-like symptoms among occupants that improve when leaving the building; past water damage not dried within 24 to 48 hours; relative humidity consistently above 60%. Any of these in your Mayville home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.

We communicate with your Mayville adjuster directly when that helps the process.
