Does Alberta home insurance cover water damage?

First, the honest caveat: we're a restoration contractor, not an insurance broker. Policies differ, and your broker is the authority on yours. But after working alongside adjusters on many Alberta claims, here's the pattern almost every homeowner encounters.

Usually covered: sudden and accidental

The standard Alberta homeowner policy covers water damage that is sudden and accidental from inside the home:

• Burst or frozen pipes (if the home was heated or drained appropriately)
• Appliance failures — washing machine hoses, dishwashers, water heaters
• Bathtub or sink overflow

Usually needs an endorsement: the two big ones

• Sewer backup coverage. Water coming up the floor drain or toilet during a storm is typically excluded unless you bought the sewer backup endorsement. After Calgary's hail-and-downpour events, this is the claim type we see denied most often on basic policies.
• Overland water coverage. River flooding, spring runoff, and rain entering at ground level were essentially uninsurable in Canada before 2013; now most insurers sell overland water as an add-on. If you're anywhere near the Bow, Elbow, Sheep, or Highwood rivers — or in a low-lying neighbourhood — check whether you carry it.

Usually NOT covered

• Gradual damage — the slow leak under the sink that rotted the cabinet over months. Insurers treat this as maintenance.
• Seepage through foundation cracks over time
• Freezing while away — many policies require someone checking the home (often every 24–72 hours) or the water shut off when you travel in winter. Read yours before your next vacation.

How to protect your claim after a loss

• Report immediately and get a claim number
• Photograph everything before cleanup; keep damaged items until the adjuster says otherwise
• Mitigate promptly — policies require you to prevent further damage, and professional drying logs (moisture readings, equipment placement, daily monitoring) are exactly the documentation adjusters want
• Keep every receipt, including emergency purchases
