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.

If inspection finds no actionable issue in your California property, we tell you that honestly. We don't manufacture work that isn't needed.

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.

Found black mold in our California home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately.

That's exactly how it should work.
My California restaurant was flagged for mold during a health inspection. Called Koppers Waterproofing that morning. Crew on-site by noon, affected prep area contained without shutting down the full kitchen, clean clearance report before my reinspection. Saved us from a week-long closure. They understood exactly what was at stake.
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.
