Does insurance cover water damage?
Usually yes when it is sudden and accidental, and usually no when it is gradual. That single distinction decides most residential water claims in British Columbia.
A pipe that bursts overnight and floods a finished basement is the textbook covered event. A supply line that wept behind a wall for eight months until the drywall softened is the textbook denial, because insurers treat slow deterioration as maintenance rather than an insurable accident.
What is usually covered, and what usually is not?
The table below reflects how standard BC homeowner policies commonly treat each scenario. Policies differ and endorsements change the answer, so treat it as orientation and confirm your own wording.
| Scenario | Commonly | What decides it |
|---|---|---|
| Burst supply pipe | Covered | Sudden and accidental |
| Water tank or appliance failure | Covered | Sudden and accidental |
| Slow leak under a sink over months | Not covered | Gradual, treated as maintenance |
| Sewer or septic backing up into the home | Only with a sewer backup endorsement | Endorsement present or absent |
| Surface water entering from outside | Only with an overland water endorsement | Separate coverage from internal water |
| Frozen pipe while the home was heated | Commonly covered | Sudden, and the home was maintained |
| Frozen pipe in an unheated, unattended home | Often excluded | Policies commonly require heat be maintained |

What should you do in the first hour?
Stop the water, make the space safe, then document before anything is moved. The order matters, because the evidence a claim rests on is destroyed by the cleanup that the same claim requires you to perform.
- Shut off the water at the source, or the main if you cannot isolate it
- Kill power to affected areas at the breaker if water is anywhere near outlets or fixtures, and stay out if you are unsure
- Photograph and video everything, wide shots and close ups, before moving a single item
- Call your insurer to open the claim and get the claim number
- Start mitigation: extract standing water and get air moving, because most policies require you to prevent further damage
- Keep every receipt, and keep damaged materials where possible until the adjuster has seen them
Why does the delay matter so much?
Because water damage does not stay a water problem. Wet building materials in a Lower Mainland home support mold growth quickly, and a claim that started as a covered burst pipe can develop a mold component that the policy treats differently.
Documented, prompt mitigation is also the strongest answer to the question an adjuster will eventually ask, which is whether the loss was made worse by how long it sat.
What does a restoration company actually do for the claim?
Beyond drying the building, the useful output is documentation: moisture readings, what was removed and why, photographs through the process, and a scope an adjuster can reconcile against the estimate.
You choose the restoration contractor. An insurer may suggest a preferred vendor and you are generally free to use your own; confirm the billing arrangement with the adjuster before work starts so there is no dispute about it afterwards.
