Every Hewlett emergency call gets same-day response as the operational standard. We don't send a technician to "assess and schedule" — our crews arrive with everything needed to begin containment and remediation on the first visit.

Toxigenic mold species — particularly Stachybotrys — appear in Hewlett 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 Hewlett black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
If you suspect black mold in your Hewlett property, call +1-866-476-1348 immediately. Don't disturb the area — let certified technicians handle it safely.

We were buying a home in Hewlett 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 Hewlett.
My Hewlett 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 Hewlett 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.
