HOMEOWNER GUIDE · UPDATED OCTOBER 27, 2026

Does homeowners insurance cover water damage? A plain guide for Washington and Oregon homeowners

It usually depends on where the water came from and how suddenly it happened. Here is how policies commonly treat leaks, burst pipes, floods and sewer backups, and how to document a claim.

It usually depends on where the water came from and how suddenly it happened. Many standard homeowners policies cover sudden, accidental water damage from inside the home, such as a burst pipe or a broken supply line. Damage from a slow leak, from flooding that comes in from outside, or from a sewer backup is often excluded or needs separate coverage. Your policy and your insurer decide, so read the policy and ask your agent when something is unclear.

This is general information to help you ask better questions. It is not insurance or legal advice.

Water damage that is often covered

Policies are usually written around damage that is sudden and accidental. Common examples include:

  • A pipe that bursts, including one that freezes and splits
  • A supply line that breaks under a sink, toilet, washer or dishwasher
  • A water heater that suddenly fails
  • Rain coming through a roof that was damaged by a storm

Even when the water damage is covered, many policies don't pay to repair the pipe or appliance that failed. They cover the damage the water caused.

Water damage that is often not covered

  • Slow leaks. A drip under a sink or behind a shower that went on for weeks or months is often treated as a maintenance issue.
  • Flooding from outside. Rising water from heavy rain, a river or surface runoff is usually a flood. FloodSmart, the federal flood insurance program site, notes that most homeowners insurance does not cover flood damage. Flood coverage is a separate policy.
  • Sewer or drain backup. Water that backs up through a floor drain, toilet or tub often needs a specific add-on to the policy. Ask your agent whether you have it. Our guide on what to do after a sewage backup covers the safety side.
  • Long-term moisture and mold. Mold that grew from an ongoing leak may be excluded or limited.

If you are not sure which category your situation falls into, describe what happened to your insurer plainly and let them tell you how the policy applies.

How to document water damage for a claim

Good records make the conversation with your insurer easier, whatever the outcome.

  1. Stop the water if you can do it safely. Shut off the main valve or the fixture's valve. If you can't, call for help.
  2. Take photos and video before you move anything. Get wide shots of each room and close-ups of the source, the water line on walls and damaged belongings.
  3. List damaged items with rough ages and where they were bought, if you know.
  4. Keep receipts for the plumber, emergency supplies and any other costs the damage caused.
  5. Call your insurer promptly and write down the claim number and your adjuster's name.
  6. Prevent more damage. Most policies expect you to take reasonable steps to keep the damage from getting worse, and starting the drying quickly is part of that. The EPA says it is important to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth.

Ask your adjuster before throwing away damaged materials. Photos help, but some insurers want to see certain items.
