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.
We coordinate with homeowners insurance carriers in California when situations qualify. Documentation is prepared for carrier submission from day one — inspection reports, lab results, photo documentation, remediation scope, and clearance reports.
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.
Attempting DIY removal in California without containment is one of the most common ways a localized problem becomes a building-wide crisis. Our protocol prevents that.
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.
Remediation removes the active colony. Prevention keeps it from coming back — which in California's seasonal weather environment requires addressing the moisture source directly. Every Koppers Waterproofing project in California includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for California customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Found black mold in our California home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our California 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 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.
Clear information before any California property owner commits to anything.

Signs that warrant a professional Exterior Waterproofing inspection in your California property: visible dark spotting on walls, ceilings, or floors; persistent musty odor in bathrooms, basements, or after water events; allergy-like symptoms among occupants that improve when leaving the building; past water damage not dried within 24 to 48 hours; relative humidity consistently above 60%. Any of these in your California home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.

Properly performed remediation eliminates the active colony. Recurrence happens when the underlying moisture condition isn't resolved — because mold spores are naturally present in every indoor environment at trace levels. Every Koppers Waterproofing project in California addresses the moisture source as a required deliverable. We identify the cause, document it, and provide specific prevention recommendations for your California property type. Our optional maintenance program includes 30-day and 90-day follow-up air quality checks for California customers.
