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

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