Mold Assist is Toronto’s trusted leader in mold remediation, delivering expert solutions tailored to the city’s unique challenges.

Mold Assist follows a proven, IICRC-compliant process to deliver effective and safe mold removal in Toronto. Our methodical approach eliminates mold, prevents recurrence, and restores your property’s air quality.
Toronto’s humid continental climate—marked by summer humidity levels up to 70% and winter condensation from freeze-thaw cycles—creates a haven for mold growth. Basements, attics, and HVAC systems in homes across neighborhoods like Leslieville or high-rises in North York are particularly vulnerable. The Canadian Lung Association reports that GTA residents face a 25–30% higher risk of mold-related health issues due to the region’s climate.
Health Risks: Mold spores can trigger allergies, asthma, sinus infections, and chronic respiratory problems, especially for children, seniors, or those with compromised immune systems.
Property Damage: Mold erodes drywall, wood, and insulation, leading to repair costs ranging from $8,000 to $20,000. For real estate, undisclosed mold can reduce property values by 5–10% or derail sales. Businesses in areas like the Financial District risk OHSA fines up to $1,500 for poor air quality.
