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.

Homeowners and business operators in Ontario — real testimonials from people who called Zaguilan Roofing Service when mold became a real problem.
We were buying a home in Ontario and mold showed up on the inspection report two days before closing. I called Zaguilan Roofing Service 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 Zaguilan Roofing Service 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 Zaguilan Roofing Service 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.
