Insurance after water damage: storm vs. leak

We are not an insurer, adjuster or lawyer, and policies differ. This page explains why the source of water comes up in every claim, and how to keep your claim organized.

How the source shapes coverage questions

Claim checklist

• Photos and video before anything moves.
• Notes on weather and timing.
• Failed parts kept.
• Prompt notice to your insurer; write down the claim number.
• Reasonable steps to prevent further damage, with receipts.
• Moisture logs and drying records from the contractor.

Condos and HOAs

If you live in a condo or townhome, the HOA's master policy and your own HO-6 policy may both be involved. Your CC&Rs define who handles what.

California's claim timelines

The Fair Claims Settlement Practices Regulations set deadlines for insurers in California. In general:

• Within 15 calendar days of notice, the insurer must acknowledge the claim, provide forms and instructions, and begin investigating.
• Within 40 calendar days of receiving proof of claim, it must accept or deny the claim in whole or in part, or explain in writing what it needs and why more time is required, with updates every 30 days.
• Denials of first-party claims must be in writing and state the reasons and the policy provisions relied on.
• Once a claim is accepted, payment generally follows within 30 days.

What proof of claim looks like for water losses

Payments and living expenses

The California Department of Insurance's residential claims guide explains that the first check is often an advance, that structure and belongings are usually paid separately, and that additional living expenses come separately as well. Keep lodging and meal receipts if your home is unlivable.

If you disagree

The Department suggests speaking with a claims manager, then contacting the Department if needed. It accepts requests for assistance on issues such as delays and denials. Consumer hotline: 1-800-927-4357.

Wind and rain: a note on wording

Policies vary in how they treat rain entering through an opening that a storm created versus water seeping through an existing defect. Read the wording and ask your agent before storm season.

Reading your declarations page

The declarations page lists your coverage limits, deductibles and endorsements. Look for dwelling coverage, other structures, personal property, loss of use, liability, and any water backup or mold endorsements. Some policies carry a separate deductible for certain perils. Knowing these before a storm makes the claim call faster.

The first 15 days of a claim

Under 10 CCR 2695.5, once your insurer receives notice of a claim it has 15 calendar days to acknowledge it, send the forms and instructions you need, and begin investigating. That clock is a good reason to report on the day you find the water, even if you are still unsure whether rain or a pipe caused it. You can describe what you saw and add the cause later, once a plumber or roofer has looked.

Use those first days to build the record that answers the storm-or-leak question. Note the weather on the day the water appeared, keep any plumber's written findings, and photograph the exterior where you think water entered. If you shut off the main and the water kept coming during rain, write that down too. That single observation often carries more weight than any opinion.
