Homeowners and business operators in Duluth — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
Found black mold in our Duluth home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Duluth 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 Duluth and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Duluth property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Duluth commercial remediation now.
Two years of musty smell in our Duluth 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.
