Toxic Species

Stachybotrys and Toxic Mold Removal in Port Jefferson, NY

They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period.

My Port Jefferson restaurant was flagged for mold during a health inspection. Called Koppers Waterproofing that morning. Crew on-site by noon, affected prep area contained without shutting down the full kitchen, clean clearance report before my reinspection. Saved us from a week-long closure. They understood exactly what was at stake.

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.
