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