This is one of the first questions almost every homeowner asks when they find mold: will my insurance cover this? The honest answer is: it depends, and the deciding factor almost always comes down to cause.
This article provides general information only and isn't a substitute for reviewing your specific policy or speaking with your insurer or broker directly.
Why Cause Matters More Than the Mold Itself
Most Quebec home insurance policies are built around "named perils." If mold develops as a direct result of a covered event, the resulting remediation is often covered.
Mold that develops gradually — from long-term condensation, poor ventilation — is typically excluded, treated as a maintenance responsibility rather than an insurable loss.
Common Scenarios
Likely covered: A pipe bursts, floods the basement, and mold develops quickly.
Likely not covered: Attic mold that developed over several winters due to inadequate ventilation.
It depends: Cold room or bathroom mold from a slow leak.
What You Need If You're Filing a Claim
Photos, a written assessment identifying the likely cause, and a clear record of when the issue was discovered. Delayed reporting is one of the most common reasons mold claims get denied.
A Practical Next Step
Before filing anything, get an independent assessment of the mold's likely cause — this gives you accurate information to bring to your insurer.
