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

That's exactly how it should work.

Two years of musty smell in our Portland basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
