After removal, every exposed surface in your Dunkirk property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.

Found black mold in our Dunkirk home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately.

They understood exactly what was at stake.
Two years of musty smell in our Dunkirk basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
