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.
Called Koppers Waterproofing for a Chester crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost. Should have scheduled an inspection sooner.
