We find every affected area in your Markham home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.
After inspection, you receive a complete written itemized estimate for your Markham project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
Commercial mold in a Markham business creates liability exposure, regulatory risk, and operational disruption simultaneously. Koppers Waterproofing plans every Markham commercial project around your schedule — containing affected zones without shutting down what doesn't need to be stopped.
Large Markham commercial projects get a dedicated project manager, daily updates, and complete documentation for insurance carriers and regulatory bodies.
Not sure if your Markham 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.
Written report delivered within 24 to 48 hours of the Markham site visit. Call +1-866-476-1348 to schedule.
Attempting DIY removal in Markham without containment is one of the most common ways a localized problem becomes a building-wide crisis. Our protocol prevents that.
After removal, every exposed surface in your Markham 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 Markham's climate requires addressing the moisture source directly. Every Koppers Waterproofing project in Markham includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Markham customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Homeowners and business operators in Markham — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Markham 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 Markham.
I manage commercial properties in Markham and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Markham property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Markham commercial remediation now.
Two years of musty smell in our Markham 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.
Clear information before any Markham property owner commits to anything.

We identify the cause, document it, and provide specific prevention recommendations for your Markham property type. Our optional maintenance program includes 30-day and 90-day follow-up air quality checks for Markham customers.
