Toxigenic mold species — particularly Stachybotrys — appear in Marietta properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period.

If you suspect black mold in your Marietta property, call +1-866-476-1348 immediately. Don't disturb the area — let certified technicians handle it safely.

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

I manage commercial properties in Marietta and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Marietta property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Marietta commercial remediation now.
Called Koppers Waterproofing for a Marietta 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.
