Every Adelphi 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.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Adelphi emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
We find every affected area in your Adelphi home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.
We coordinate with homeowners insurance carriers in Adelphi when situations qualify. Documentation is prepared for carrier submission from day one — inspection reports, lab results, photo documentation, remediation scope, and clearance reports.
We've worked in Adelphi area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Adelphi commercial inspection as standard.
Post-remediation verification reports are provided on every Adelphi commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-866-476-1348 for a Adelphi commercial site assessment.

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