That's Koppers Waterproofing. Our certified crews serve Islip and surrounding NY communities with the same standard on every job — IICRC S520 protocol, written flat-rate pricing, and a satisfaction guarantee in writing.

We handle every phase of Crawl Space Encapsulation in Islip in-house. No subcontracting, no referrals, same certified standard from first call to final clearance test.
Every Islip 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 — Islip emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
Islip 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.
After inspection, you receive a complete written itemized estimate for your Islip project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Islip area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Islip commercial inspection as standard.
Post-remediation verification reports are provided on every Islip commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-866-476-1348 for a Islip commercial site assessment.
If inspection finds no actionable issue in your Islip property, we tell you that honestly. We don't manufacture work that isn't needed.
Pre-sale mold inspections in Islip are among our most requested services — buyers, sellers, agents, and lenders need documented mold status before transactions close. Our reports meet both insurance submission and real estate disclosure requirements in Islip, NY.
Toxigenic mold species — particularly Stachybotrys — appear in Islip 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 Islip black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Islip 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 Islip's humidity conditions requires addressing the moisture source directly. Every Koppers Waterproofing project in Islip includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Islip customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

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

Two years of musty smell in our Islip 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.
