When Lewiston homeowners and business operators deal with mold, they need a company that knows the area, shows up fast, and gives them a binding written price before touching anything. That's Koppers Waterproofing.

Every Lewiston emergency call gets same-day response as the operational standard. We don't send a technician to "assess and schedule" — our crews arrive with everything needed to begin containment and remediation on the first visit.
Call +1-866-476-1348 right now for emergency Wet Basement Repair in Lewiston. Our dispatcher will coordinate your crew while you're still on the line.
We find every affected area in your Lewiston home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.
After inspection, you receive a complete written itemized estimate for your Lewiston project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
Commercial mold in a Lewiston business creates liability exposure, regulatory risk, and operational disruption simultaneously. Koppers Waterproofing plans every Lewiston commercial project around your schedule — containing affected zones without shutting down what doesn't need to be stopped.
Large Lewiston commercial projects get a dedicated project manager, daily updates, and complete documentation for insurance carriers and regulatory bodies.
Not sure if your Lewiston property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Written report delivered within 24 to 48 hours of the Lewiston site visit. Call +1-866-476-1348 to schedule.
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.
If you suspect black mold in your Lewiston property, call +1-866-476-1348 immediately. Don't disturb the area — let certified technicians handle it safely.
Remediation removes the active colony. Prevention keeps it from coming back — which in Lewiston's humidity conditions requires addressing the moisture source directly.

Homeowners and business operators in Lewiston — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Lewiston and mold showed up on the inspection report two days before closing. I called Koppers Waterproofing in a panic. They came out the next morning, knocked it out in 48 hours, and we had the clearance report in time for the lender. Deal closed. I've already recommended them to two friends in Lewiston.
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.
Two years of musty smell in our Lewiston 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.
The questions Lewiston homeowners and business operators ask before hiring for Wet Basement Repair — answered directly.

Signs that warrant a professional Wet Basement Repair 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.
Standard homeowners insurance in Lewiston typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure. Mold from gradual neglect is generally excluded under NY policies. Koppers Waterproofing provides complete documentation packages structured for Lewiston insurance carrier submission: inspection reports, certified lab analysis, photo documentation, remediation scope, and clearance reports. We communicate with your Lewiston adjuster directly when that helps the process.
Our Lewiston remediation is designed to last — and we back it with a written satisfaction guarantee. For customers who want ongoing documented verification, our maintenance program provides follow-up air quality checks at 30 and 90 days.
