Markham 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 Markham project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Markham area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Markham commercial inspection as standard.

If inspection finds no actionable issue in your Markham property, we tell you that honestly. We don't manufacture work that isn't needed.

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.
Found black mold in our Markham home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Markham property the next morning with a written estimate before they looked at anything. Done in 48 hours, air clearance test passed, price matched exactly what they quoted. That's exactly how it should work.
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.
Called Koppers Waterproofing for a Markham 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.
