Ontario 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 Ontario 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 Ontario area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Ontario commercial inspection as standard.
Post-remediation verification reports are provided on every Ontario commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-866-476-1348 for a Ontario commercial site assessment.
If inspection finds no actionable issue in your Ontario 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 Ontario site visit. Call +1-866-476-1348 to schedule.
Attempting DIY removal in Ontario 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 Ontario 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 Ontario's humidity conditions requires addressing the moisture source directly. Every Koppers Waterproofing project in Ontario includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Ontario customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Real situations. Real Ontario customers. Real results.
We were buying a home in Ontario 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 Ontario.
I manage commercial properties in Ontario and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Ontario property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Ontario commercial remediation now.
Two years of musty smell in our Ontario 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.
