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.
After removal, every exposed surface in your California 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 California — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
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.
