Found black mold in our Sewell home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Sewell property the next morning with a written estimate before they looked at anything. Done in 48 hours, air clearance test passed, price matched exactly what they quoted. That's exactly how it should work.
My Sewell 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 Sewell basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
