The short answer
Homeowners insurance often covers water damage that is sudden and accidental, such as a burst pipe, a failed water heater or a broken appliance supply line. According to the National Association of Insurance Commissioners (NAIC), policies generally cover damage from a sudden and accidental discharge of water, but a frozen pipe claim may be denied if the insurer finds you didn't take reasonable steps to prevent freezing. Water damage from gradual leaks, outside flooding, and sewer or sump backups is commonly excluded unless you have specific coverage.
This is general information, not insurance advice. Your policy wording decides your coverage, so read it and talk to your insurer or agent.
What's typically covered and what isn't
| Cause of water damage | Typical treatment under a standard policy |
|---|---|
| Burst pipe in a heated, occupied home | Often covered (water damage), minus your deductible |
| Water heater, washing machine or dishwasher failure | Often covered for sudden damage |
| Storm or hail damage to the roof that lets rain in | Often covered, subject to policy terms |
| Slow leak over weeks or months | Often excluded as gradual damage or maintenance |
| Sewer or drain backup | Commonly requires a water backup endorsement |
| Sump pump failure or overflow | Commonly requires a water backup endorsement |
| Flooding from rivers, storm runoff or groundwater | Generally excluded; requires separate flood insurance |
| Mold | Varies widely; sometimes covered with limits after a covered loss |
Water backup endorsements
A water backup endorsement is optional coverage added to a homeowners policy. It commonly covers damage when water backs up through sewers or drains, or overflows from a sump. Because sewer backups and sump pump failures are common causes of basement water damage, it's worth checking whether your policy includes one and what its limit is.
Flood insurance is separate
Damage from rising water that comes from outside, such as river flooding or storm runoff, is generally excluded from standard homeowners policies and needs separate flood insurance. Many homeowners buy it through the National Flood Insurance Program. This matters in parts of the area near rivers, such as Eureka along the Meramec River.
How to file a water damage claim
Stop the water and prevent more damage
Policies commonly expect you to take reasonable steps to limit further damage. Shut off the water and start drying.
Document before cleanup
Photograph and video the source, standing water, water lines on walls, and all damaged items.
Report the claim promptly
Call your insurer and ask whether they want to inspect before materials are removed.
Keep drying records and receipts
Ask the restoration provider for moisture readings and itemized invoices. Keep receipts for emergency costs.
Meet the adjuster prepared
Have photos, receipts and the provider's documentation ready.
If your claim is denied
Ask for the denial in writing, with the policy language it relies on. Compare it with your policy and ask your agent to review it.
