HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — California emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
We find every affected area in your California 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 California 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 California black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
If you suspect black mold in your California property, call +1-866-476-1348 immediately. Don't disturb the area — let certified technicians handle it safely.
Remediation removes the active colony. Prevention keeps it from coming back — which in California's seasonal weather environment requires addressing the moisture source directly.

We earn these reviews by doing exactly what we said we'd do.
We were buying a home in California 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 California.
I manage commercial properties in California and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the California property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for California commercial remediation now.
Called Koppers Waterproofing for a California 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.
Clear information before any California property owner commits to anything.
