Black Mold

Toxigenic Mold Elimination in Smithtown

Toxigenic mold species — particularly Stachybotrys — appear in Smithtown properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Smithtown black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.

If you suspect black mold in your Smithtown property, call +1-866-476-1348 immediately. Don't disturb the area — let certified technicians handle it safely.

Two years of musty smell in our Smithtown 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.
