HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Closter emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
We find every affected area in your Closter home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.
After inspection, you receive a complete written itemized estimate for your Closter project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.

Post-remediation verification reports are provided on every Closter commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-866-476-1348 for a Closter commercial site assessment.
If inspection finds no actionable issue in your Closter property, we tell you that honestly. We don't manufacture work that isn't needed.

Toxigenic mold species — particularly Stachybotrys — appear in Closter 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 Closter black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Closter property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Remediation removes the active colony. Prevention keeps it from coming back — which in Closter's climate requires addressing the moisture source directly. Every Koppers Waterproofing project in Closter includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Closter customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Found black mold in our Closter home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Closter property the next morning with a written estimate before they looked at anything. Done in 48 hours, air clearance test passed, price matched exactly what they quoted. That's exactly how it should work.
My Closter 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.
Called Koppers Waterproofing for a Closter crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost. Should have scheduled an inspection sooner.

Signs that warrant a professional Waterproofing inspection in your Closter property: visible dark spotting on walls, ceilings, or floors; persistent musty odor in bathrooms, basements, or after water events; allergy-like symptoms among occupants that improve when leaving the building; past water damage not dried within 24 to 48 hours; relative humidity consistently above 60%. Any of these in your Closter home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.
Standard homeowners insurance in Closter typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure.

We communicate with your Closter adjuster directly when that helps the process.
Mold recurrence in Closter properties almost always traces to an unresolved moisture source — not to failed remediation work. We address this directly by identifying and documenting the cause on every project. Call +1-866-476-1348 to learn more about our Closter prevention services.
