Homeowners and business operators in Derwood — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
Found black mold in our Derwood home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Derwood 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.
I manage commercial properties in Derwood and I've dealt with enough remediation contractors to know the difference.

Two years of musty smell in our Derwood basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Koppers Waterproofing removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
