Found black mold in our Mayville home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Mayville 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.
My Mayville 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 Mayville 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.

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 Mayville addresses the moisture source as a required deliverable. We identify the cause, document it, and provide specific prevention recommendations for your Mayville property type. Our optional maintenance program includes 30-day and 90-day follow-up air quality checks for Mayville customers.
