We don't subcontract in Markesan. We don't send uncredentialed labor. We don't begin work without a signed written estimate. These aren't competitive points — they're the operating standards that have earned us the Markesan customers who call back and refer friends.
Every mold situation in Markesan gets the same certified approach from Koppers Waterproofing — inspection, written estimate, S520 protocol, and air clearance before the job closes.
Mold emergencies in Markesan don't wait for business hours. When a pipe bursts, a storm floods a crawl space, or water damage creates conditions for rapid mold growth, Koppers Waterproofing dispatches immediately.

HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Markesan emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
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.

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 humidity conditions 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.

Two years of musty smell in our Markesan basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
