We were buying a home in Demarest 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 Demarest.
I manage commercial properties in Demarest and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Demarest property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Demarest commercial remediation now.
Called Koppers Waterproofing for a Demarest 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 Wet Basement Repair inspection in your Demarest 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 Demarest 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 Demarest adjuster directly when that helps the process.
