We were buying a home in Williston Park and mold showed up on the inspection report two days before closing. I called Koppers Waterproofing in a panic.

They understood exactly what was at stake.
Two years of musty smell in our Williston Park basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
