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.

Signs that warrant a professional Black Mold Remediation inspection in your Markham property: visible dark spotting on walls, ceilings, or floors; persistent musty odor in bathrooms, basements, or after water events; allergy-like symptoms among occupants that improve when leaving the building; past water damage not dried within 24 to 48 hours; relative humidity consistently above 60%. Any of these in your Markham home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.

Properly performed remediation eliminates the active colony. Recurrence happens when the underlying moisture condition isn't resolved — because mold spores are naturally present in every indoor environment at trace levels. Every Koppers Waterproofing project in Markham addresses the moisture source as a required deliverable. 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.
