Mold remediation is the process of finding the source of moisture, containing the affected area, removing contaminated material, and cleaning the space so mold doesn't come back. In Vaughan, that usually means basements after a sump pump failure or foundation seepage, bathrooms and laundry rooms with poor ventilation, and attics where roof leaks or bad insulation trap humidity. It's a different job from a general cleanup: a real remediation crew tests or inspects before quoting, seals off the work area with plastic sheeting and negative air pressure to stop spores spreading through the HVAC system, removes and bags drywall, insulation, or flooring that can't be salvaged, then wipes down and treats remaining surfaces with an antimicrobial. Some jobs also need air scrubbers running for a day or two after the physical cleanup.
When comparing companies, ask whether they do a moisture inspection before quoting, whether containment and negative air pressure are part of the plan (not just a wipe-down), how they handle disposal of contaminated material, and whether they offer any post-job verification. Get a written scope, not just a price.
