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 Mold Remediation HQ 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. Mold Remediation HQ 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. Mold Remediation HQ removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
