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.
We coordinate with homeowners insurance carriers in Markham when situations qualify. Documentation is prepared for carrier submission from day one — inspection reports, lab results, photo documentation, remediation scope, and clearance reports.
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.
Large Markham commercial projects get a dedicated project manager, daily updates, and complete documentation for insurance carriers and regulatory bodies.
If inspection finds no actionable issue in your Markham property, we tell you that honestly. We don't manufacture work that isn't needed.
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.

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.

Signs that warrant a professional Wet Basement Repair 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.
