Why this risk dominates
Water damage now accounts for the largest share of home insurance claims in Quebec, ahead of fire and theft. Insurers have therefore split the coverage into several distinct parts.
Water from inside
A burst pipe, a failed water heater, a leaking dishwasher: this kind of loss is generally covered under the base policy, often with its own deductible and sometimes with an exclusion for neglected maintenance.
Sewer backup
Backup through drains, sewers, or a septic tank is almost always a separate endorsement. Without it, a basement flooded by a backup is not paid.
Seepage and overflow
Water seeping through foundations, the roof, or windows, and the overflow of a body of water, fall under still other endorsements. Flooding by overflow is sometimes excluded in high-risk zones, or subject to an increased deductible.
The specific deductible
Water-related endorsements frequently carry a deductible above the policy’s own, sometimes expressed as a percentage of the insured amount. An existing coverage with a very high deductible can amount in practice to no coverage.
Maintenance obligations
Policies impose duties: a working backflow valve, heating maintained while away, draining the system, declaring renovations. Failing one of these conditions supports a denial.
The review to do
Find each water-related coverage on your declarations page, with its deductible and its limit. A damage insurance broker does that review with you and compares the endorsements actually available.
