Lewiston homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action. Koppers Waterproofing delivers all three — thermal imaging, air sampling, written estimate, and IICRC S520 protocol from the first inspection through final air clearance testing.
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.

Our Lewiston black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.

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.
My Lewiston restaurant was flagged for mold during a health inspection. Called Koppers Waterproofing that morning. Crew on-site by noon, affected prep area contained without shutting down the full kitchen, clean clearance report before my reinspection. Saved us from a week-long closure. They understood exactly what was at stake.
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.

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.
