Markesan 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.
We coordinate with homeowners insurance carriers in Markesan when situations qualify. Documentation is prepared for carrier submission from day one — inspection reports, lab results, photo documentation, remediation scope, and clearance reports.
Commercial mold in a Markesan business creates liability exposure, regulatory risk, and operational disruption simultaneously. Koppers Waterproofing plans every Markesan commercial project around your schedule — containing affected zones without shutting down what doesn't need to be stopped.
Post-remediation verification reports are provided on every Markesan commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-866-476-1348 for a Markesan commercial site assessment.
Not sure if your Markesan property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Written report delivered within 24 to 48 hours of the Markesan site visit. Call +1-866-476-1348 to schedule.
Toxigenic mold species — particularly Stachybotrys — appear in Markesan properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Markesan black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Markesan property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Prevention services for Markesan properties include crawl space encapsulation, vapor barrier installation, dehumidification system design, ventilation assessments, and structural moisture intrusion identification.

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

We communicate with your Markesan adjuster directly when that helps the process.
