Toxigenic mold species — particularly Stachybotrys — appear in Lewiston 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. Our Lewiston black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Lewiston property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Prevention services for Lewiston properties include crawl space encapsulation, vapor barrier installation, dehumidification system design, ventilation assessments, and structural moisture intrusion identification.

Found black mold in our Lewiston home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Lewiston 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 Lewiston and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Lewiston property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Lewiston commercial remediation now.
Called Koppers Waterproofing for a Lewiston 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.
Clear information before any Lewiston property owner commits to anything.

Signs that warrant a professional Exterior Waterproofing inspection in your Lewiston property: visible dark spotting on walls, ceilings, or floors; persistent musty odor in bathrooms, basements, or after water events; allergy-like symptoms among occupants that improve when leaving the building; past water damage not dried within 24 to 48 hours; relative humidity consistently above 60%. Any of these in your Lewiston home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.
