Found black mold in our Marshall home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Marshall 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 Marshall and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Marshall property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Marshall commercial remediation now.
Called Koppers Waterproofing for a Marshall crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost. Should have scheduled an inspection sooner.
