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.
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.

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.
Pre-sale mold inspections in California are among our most requested services — buyers, sellers, agents, and lenders need documented mold status before transactions close. Our reports meet both insurance submission and real estate disclosure requirements in California, KY.

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.
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.
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.
