We find every affected area in your Markesan home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.
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.
We've worked in Markesan area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Markesan commercial inspection as standard.
Large Markesan commercial projects get a dedicated project manager, daily updates, and complete documentation for insurance carriers and regulatory bodies.
If inspection finds no actionable issue in your Markesan property, we tell you that honestly. We don't manufacture work that isn't needed.
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.
Remediation removes the active colony. Prevention keeps it from coming back — which in Markesan's seasonal weather environment requires addressing the moisture source directly. Every Koppers Waterproofing project in Markesan includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Markesan customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Real situations. Real Markesan customers. Real results.
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.
My Markesan 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.
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.
