Homeowners and business operators in Williston — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Williston 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 Williston.
I manage commercial properties in Williston and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Williston property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Williston commercial remediation now.
Called Koppers Waterproofing for a Williston 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.
