We find every affected area in your Chester home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.

We earn these reviews by doing exactly what we said we'd do.
We were buying a home in Chester 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 Chester.
I manage commercial properties in Chester and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Chester property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Chester commercial remediation now.
Two years of musty smell in our Chester 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.
