Marshall 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.
After inspection, you receive a complete written itemized estimate for your Marshall project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Marshall area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Marshall commercial inspection as standard.
Post-remediation verification reports are provided on every Marshall commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-866-476-1348 for a Marshall commercial site assessment.
Not sure if your Marshall 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.
Pre-sale mold inspections in Marshall are among our most requested services — buyers, sellers, agents, and lenders need documented mold status before transactions close. Our reports meet both insurance submission and real estate disclosure requirements in Marshall, MN.
Toxigenic mold species — particularly Stachybotrys — appear in Marshall 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 Marshall black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Marshall 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 Marshall's climate requires addressing the moisture source directly. Every Koppers Waterproofing project in Marshall includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Marshall customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

We were buying a home in Marshall 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 Marshall.
My Marshall 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 Marshall 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.
