How Insurance Covers Water Damage (And When It Doesn't)

The core rule: sudden and accidental

Standard homeowner policies cover water damage that is sudden and accidental: burst pipes, water heater ruptures, washing machine hose failures, accidental tub overflows. The event is unexpected, so it's covered.

What's typically excluded

Gradual damage — the slow leak under a sink that rotted the cabinet over months — is usually excluded as a maintenance issue. Rising water from outside (flood) is excluded and requires separate flood insurance. Sewer and drain backups need a specific rider many homeowners don't know they lack.

Why documentation decides claims

The difference between 'sudden pipe failure' and 'long-term leak' is often determined by evidence: photos, moisture patterns, and the professional mitigation report. This is a major reason to use licensed restoration companies — their documentation is written for adjusters.

Your duty to mitigate

Every policy requires you to take reasonable steps to prevent further damage. Waiting a week for an adjuster while water sits is grounds to reduce your payout. Document first, then begin professional mitigation immediately.

Practical steps for a smooth claim

Report promptly and get your claim number. Photograph everything before cleanup. Keep damaged materials until approved for disposal. Save every receipt, including emergency purchases. Get the restoration company's moisture logs and scope of work in writing.

If a claim is disputed, you can request re-inspection, provide additional documentation, or in significant losses consider a licensed public adjuster.
