Ontario properties face specific mold challenges driven by the humidity conditions in this part of NY. Our crews understand those conditions, which means faster accurate assessments and remediation that addresses the actual cause — not just the visible symptom.

Toxigenic mold species — particularly Stachybotrys — appear in Ontario properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Ontario black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.

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.
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.
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.

Signs that warrant a professional Foundation Crack Repair inspection in your Ontario 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 Ontario home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.
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.
Mold recurrence in Ontario properties almost always traces to an unresolved moisture source — not to failed remediation work. We address this directly by identifying and documenting the cause on every project. Call +1-866-476-1348 to learn more about our Ontario prevention services.
