Saint Louis homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action. Koppers Waterproofing delivers all three — thermal imaging, air sampling, written estimate, and IICRC S520 protocol from the first inspection through final air clearance testing.
After inspection, you receive a complete written itemized estimate for your Saint Louis project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.

After removal, every exposed surface in your Saint Louis 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 Saint Louis's climate requires addressing the moisture source directly.

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