Westchester 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 Westchester project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Westchester area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Westchester commercial inspection as standard.
Large Westchester commercial projects get a dedicated project manager, daily updates, and complete documentation for insurance carriers and regulatory bodies.
Not sure if your Westchester 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.
Pre-sale mold inspections in Westchester 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 Westchester, IL.
Toxigenic mold species — particularly Stachybotrys — appear in Westchester 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 Westchester black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Westchester property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Prevention services for Westchester properties include crawl space encapsulation, vapor barrier installation, dehumidification system design, ventilation assessments, and structural moisture intrusion identification.

We were buying a home in Westchester 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 Westchester.
I manage commercial properties in Westchester and I've dealt with enough remediation contractors to know the difference.

Two years of musty smell in our Westchester 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.
