How Much Does Mold Removal Cost in Toronto?

Five factors dominate the cost: affected area size, contamination severity (Condition 1, 2, or 3 per IICRC S520), location difficulty (attic, crawlspace, wall cavities are more expensive), containment requirements (full poly containment with negative air adds cost), and whether reconstruction is needed after remediation. Pre-1990 homes often add asbestos testing and potential abatement cost.

Only when the mold resulted from a covered water damage event (burst pipe, appliance failure, storm damage). Most Ontario homeowner policies cover mold remediation up to a sub-limit - typically $5,000-$10,000 when the underlying cause is covered. Mold from long-term leaks, humidity, or deferred maintenance is excluded. We document the moisture source during assessment so your claim matches what the policy will pay.
