California 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 California project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in California area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every California commercial inspection as standard.
Large California commercial projects get a dedicated project manager, daily updates, and complete documentation for insurance carriers and regulatory bodies.
Not sure if your California property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Written report delivered within 24 to 48 hours of the California site visit. Call +1-866-476-1348 to schedule.
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.
Prevention services for California properties include crawl space encapsulation, vapor barrier installation, dehumidification system design, ventilation assessments, and structural moisture intrusion identification.

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.
Two years of musty smell in our California basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Koppers Waterproofing removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
