Homeowners and business operators in Old Westbury — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Old Westbury 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 Old Westbury.

Called Koppers Waterproofing for a Old Westbury 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.
