Randolph homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action.

Pre-sale mold inspections in Randolph 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 Randolph, MN.
Toxigenic mold species — particularly Stachybotrys — appear in Randolph 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 Randolph black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Randolph 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 Randolph's seasonal weather environment requires addressing the moisture source directly. Every Koppers Waterproofing project in Randolph includes moisture source identification and documented prevention recommendations as standard deliverables.

Homeowners and business operators in Randolph — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Randolph 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 Randolph.
My Randolph 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 Randolph 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.
