Our Port Jefferson black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.

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

Two years of musty smell in our Port Jefferson 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.
