They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Sterling black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Sterling property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.

Homeowners and business operators in Sterling — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
Found black mold in our Sterling home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Sterling property the next morning with a written estimate before they looked at anything. Done in 48 hours, air clearance test passed, price matched exactly what they quoted. That's exactly how it should work.
I manage commercial properties in Sterling and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Sterling property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Sterling commercial remediation now.
Called Koppers Waterproofing for a Sterling 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.
