We find every affected area in your Marshall home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.

Toxigenic mold species — particularly Stachybotrys — appear in Marshall 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 Marshall black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Marshall 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 Marshall's climate requires addressing the moisture source directly. Every Koppers Waterproofing project in Marshall includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Marshall 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 Marshall 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 Marshall.
I manage commercial properties in Marshall and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Marshall property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Marshall commercial remediation now.
Called Koppers Waterproofing for a Marshall 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.
