Homeowners and business operators in Demarest — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Demarest 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 Demarest.
I manage commercial properties in Demarest and I've dealt with enough remediation contractors to know the difference.

They're the only company I call for Demarest commercial remediation now.
Two years of musty smell in our Demarest 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.
