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. 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 Randolph project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
Commercial mold in a Randolph business creates liability exposure, regulatory risk, and operational disruption simultaneously. Koppers Waterproofing plans every Randolph commercial project around your schedule — containing affected zones without shutting down what doesn't need to be stopped.

They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period.

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.

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.
I manage commercial properties in Randolph and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Randolph property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Randolph commercial remediation now.
Two years of musty smell in our Randolph basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Koppers Waterproofing removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
