Most homeowners policies cover water damage that's sudden and accidental, like a burst pipe or an appliance that suddenly fails. They usually don't cover floods, slow leaks over time, or sewer backups unless you added that coverage.
The rule insurers use: sudden and accidental
A standard homeowners policy (usually called an HO-3) is written to cover damage that happens suddenly and by accident. Water that bursts out of a pipe overnight fits. Water that seeped from a slow drip for months usually doesn't, because the insurer treats that as maintenance or wear and tear.
Usually covered
- Burst or broken pipes, including frozen pipes in a heated home. See what to do after a burst pipe.
- Appliance failures like a water heater, washer or dishwasher supply line that suddenly lets go.
- Accidental overflow from a tub, sink or toilet.
- Water from firefighting or from rain that gets in after a storm damages the roof.
Usually not covered
- Flooding from rising surface water, rivers or storm surge. That takes a separate flood policy.
- Sewer or drain backup and sump pump failure, unless you bought a water backup endorsement.
- Slow, repeated leaks and the damage they cause over time.
- Groundwater seeping through foundations or basement floors.
- Mold beyond a set limit, often a few thousand dollars.
What decides your claim
Your own policy, not general rules. Look at your declarations page for your deductible and any endorsements, then read the water damage and exclusions sections. If something is unclear, ask the insurance company to point to the exact policy language they're relying on.
Protect the claim from day one
Stop the water, photograph everything before it's moved, and start drying quickly. Policies require you to prevent further damage, and fast drying is one of the clearest ways to show you did.
Common questions
Is a slow leak ever covered?
Sometimes the resulting damage is covered if the leak was hidden and you couldn't reasonably have known about it. It depends on the policy wording and the facts.
Does homeowners insurance cover flood damage?
No. Flood damage needs a separate flood policy, either through FEMA's National Flood Insurance Program or a private insurer.
Should I call a restoration company before the insurance company?
If water is still coming in or sitting in the house, start mitigation right away and report the claim the same day. Waiting can make the damage, and the claim, worse.
