Merrick 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 Merrick project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.

Homeowners and business operators in Merrick — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Merrick 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 Merrick.
I manage commercial properties in Merrick and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Merrick property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Merrick commercial remediation now.
Two years of musty smell in our Merrick 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.

Signs that warrant a professional Exterior Waterproofing inspection in your Merrick 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 Merrick home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.

We communicate with your Merrick adjuster directly when that helps the process.
