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 Waterproofing — answered directly.

Signs that warrant a professional 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.
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 MN 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.
Properly performed remediation eliminates the active colony. Recurrence happens when the underlying moisture condition isn't resolved — because mold spores are naturally present in every indoor environment at trace levels. Every Koppers Waterproofing project in Lewiston addresses the moisture source as a required deliverable. We identify the cause, document it, and provide specific prevention recommendations for your Lewiston property type. Our optional maintenance program includes 30-day and 90-day follow-up air quality checks for Lewiston customers.
