When Ontario homeowners and business operators deal with mold, they need a company that knows the area, shows up fast, and gives them a binding written price before touching anything. That's Koppers Waterproofing. Our certified crews serve Ontario and surrounding NY communities with the same standard on every job — IICRC S520 protocol, written flat-rate pricing, and a satisfaction guarantee in writing.

Mold emergencies in Ontario don't wait for business hours. When a pipe bursts, a storm floods a crawl space, or water damage creates conditions for rapid mold growth, Koppers Waterproofing dispatches immediately. Our emergency line for Ontario is live 24/7 with real dispatchers — not voicemail, not a callback window.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Ontario emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
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.
After inspection, you receive a complete written itemized estimate for your Ontario project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
Commercial mold in a Ontario business creates liability exposure, regulatory risk, and operational disruption simultaneously. Koppers Waterproofing plans every Ontario commercial project around your schedule — containing affected zones without shutting down what doesn't need to be stopped.
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.
Not sure if your Ontario property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Pre-sale mold inspections in Ontario are among our most requested services — buyers, sellers, agents, and lenders need documented mold status before transactions close. Our reports meet both insurance submission and real estate disclosure requirements in Ontario, NY.
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.

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.
