Here's the full Sullivan service lineup.
Every Sullivan 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 — Sullivan emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
Sullivan homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action. Koppers Waterproofing delivers all three — thermal imaging, air sampling, written estimate, and IICRC S520 protocol from the first inspection through final air clearance testing.
We coordinate with homeowners insurance carriers in Sullivan 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 Sullivan area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Sullivan commercial inspection as standard.
Post-remediation verification reports are provided on every Sullivan commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-866-476-1348 for a Sullivan commercial site assessment.
Not sure if your Sullivan property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Written report delivered within 24 to 48 hours of the Sullivan site visit. Call +1-866-476-1348 to schedule.
Attempting DIY removal in Sullivan without containment is one of the most common ways a localized problem becomes a building-wide crisis. Our protocol prevents that.
After removal, every exposed surface in your Sullivan 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 Sullivan's humidity conditions requires addressing the moisture source directly. Every Koppers Waterproofing project in Sullivan includes moisture source identification and documented prevention recommendations as standard deliverables.

Homeowners and business operators in Sullivan — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
Found black mold in our Sullivan home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Sullivan 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 Sullivan 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 Sullivan 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.
