We were buying a home in Cornelius 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 Cornelius.

Two years of musty smell in our Cornelius basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
