Attempting DIY removal in Dennison without containment is one of the most common ways a localized problem becomes a building-wide crisis. Our protocol prevents that.
After removal, every exposed surface in your Dennison 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 Dennison's climate requires addressing the moisture source directly.

We were buying a home in Dennison 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 Dennison.
I manage commercial properties in Dennison and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Dennison property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Dennison commercial remediation now.
Called Koppers Waterproofing for a Dennison 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.
