We were buying a home in Williston 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 Williston.

Two years of musty smell in our Williston 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.

Signs that warrant a professional Vapor Barrier Installation inspection in your Williston 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 Williston 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 Williston typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure.

Koppers Waterproofing provides complete documentation packages structured for Williston insurance carrier submission: inspection reports, certified lab analysis, photo documentation, remediation scope, and clearance reports. We communicate with your Williston adjuster directly when that helps the process.
Mold recurrence in Williston properties almost always traces to an unresolved moisture source — not to failed remediation work. We address this directly by identifying and documenting the cause on every project. Call +1-866-476-1348 to learn more about our Williston prevention services.
