Found black mold in our Horsham home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately.

That's exactly how it should work.
My Horsham restaurant was flagged for mold during a health inspection. Called Koppers Waterproofing that morning.

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