Koppers Waterproofing has handled mold situations in Markham ranging from minor bathroom tile growth to post-flooding infestations that spread through multiple rooms. We bring the same certified standard to every job, regardless of scale.
Whether you're a Markham homeowner dealing with a weekend mold discovery or a business operator who needs commercial remediation planned around your operating schedule, Koppers Waterproofing has the crew and protocol to handle it.
Here's the full Markham service lineup.
Every Markham emergency call gets same-day response as the operational standard. We don't send a technician to "assess and schedule" — our crews arrive with everything needed to begin containment and remediation on the first visit.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Markham emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
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.
If you suspect black mold in your Markham property, call +1-866-476-1348 immediately. Don't disturb the area — let certified technicians handle it safely.
Remediation removes the active colony. Prevention keeps it from coming back — which in Markham's seasonal weather environment requires addressing the moisture source directly.

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.
My Markham 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.
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.
