Found black mold in our Ontario home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Ontario 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.
My Ontario 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.
Called Koppers Waterproofing for a Ontario 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.

For emergency calls in Ontario, we dispatch immediately with a goal of same-day arrival. Exact ETA depends on your location within Ontario and current crew positioning — call +1-866-476-1348 and our live dispatcher will give you a real-time estimate based on where crews actually are right now.

Yes — unconditionally on every Ontario project. After the initial inspection, Koppers Waterproofing provides a complete written estimate covering every cost: labor, materials, disposal, containment, antimicrobial treatment, and clearance testing. No Ontario work begins until you've reviewed and signed it. The number you sign is the invoice you pay. If we discover additional affected area during work in Ontario, we stop, document it, and present a written change order before proceeding. Your authorization, every time.

If you're asking whether you need a professional in Ontario, the answer is probably yes. Call +1-866-476-1348 and we'll assess your specific situation honestly — if there's no actionable issue in your Ontario property, we'll tell you that.
Standard homeowners insurance in Ontario typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure. Mold from gradual neglect is generally excluded under NY policies. Koppers Waterproofing provides complete documentation packages structured for Ontario insurance carrier submission: inspection reports, certified lab analysis, photo documentation, remediation scope, and clearance reports. We communicate with your Ontario adjuster directly when that helps the process.
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 Ontario addresses the moisture source as a required deliverable. We identify the cause, document it, and provide specific prevention recommendations for your Ontario property type. Our optional maintenance program includes 30-day and 90-day follow-up air quality checks for Ontario customers.
Koppers Waterproofing serves Ontario and the surrounding Ontario, NY communities — certified crews positioned to minimize response times throughout the area.
