We were buying a home in Sayville 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 Sayville.
I manage commercial properties in Sayville and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Sayville property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Sayville commercial remediation now.
Called Koppers Waterproofing for a Sayville crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost. Should have scheduled an inspection sooner.

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