We were buying a home in Markesan 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 Markesan.
I manage commercial properties in Markesan and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Markesan property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Markesan commercial remediation now.
Called Koppers Waterproofing for a Markesan crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost. Should have scheduled an inspection sooner.

Signs that warrant a professional Vapor Barrier Installation inspection in your Markesan 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 Markesan home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.

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