How to File a Homeowner's Insurance Claim for Water Damage in California
Water damage is one of the most common — and most stressful — homeowner's insurance claims in Southern California. Whether it's a burst pipe, a roof leak, a failed appliance, or flooding from a heavy storm, the first hours and days after the damage occurs are critical both for limiting further damage and for protecting your insurance claim.
Here's a clear, step-by-step guide to what you should do.
Step 1: Stop the Source and Limit Further Damage
Your first priority is stopping the water. If it's a burst pipe, shut off the water supply to that fixture or to the whole house if needed. If it's a roof leak during a storm, place buckets or lay down tarps to limit spread. Your insurance policy requires you to take reasonable steps to prevent additional damage — if you don't, the insurer may reduce or deny coverage for damage that occurred after the initial incident.
Step 2: Document Everything Before You Touch It
Before you start cleaning up, photograph and video everything. Walk every affected room. Capture:
• Standing water or wet floors
• Damaged walls, ceilings, and baseboards
• Damaged personal property
• The source of the water (the burst pipe, the leaking roof section, the failed appliance)
• Any visible mold or structural damage
The more documentation you have, the stronger your claim. Date-stamp your photos by checking your phone's image metadata, or email photos to yourself immediately to create a timestamp.
Step 3: Call Your Insurance Company
Contact your insurance company to report the loss as soon as possible. Most policies require you to report damage promptly. Have your policy number ready, and give them a basic description of what happened and when. They will assign an adjuster to your claim and schedule a time to visit your property.
Important: You are not required to have a contractor on-site during the adjuster's visit, but it can be very helpful. A contractor who knows what to look for can point out damage the adjuster might miss — and all repairs need to be documented in the adjuster's scope of loss to be covered.
Step 4: Get a Contractor Assessment
While you're waiting for the adjuster, contact a licensed contractor to assess the damage. A good contractor will:
• Document all damage — visible and hidden (moisture behind walls, under flooring, in the ceiling cavity)
• Provide a detailed written estimate of repair costs
• Help you understand what should be covered under your policy
• Identify any damage the adjuster might miss during their visit
In California, you are entitled to choose your own contractor — your insurance company cannot require you to use their preferred vendor. Make sure whoever you hire is licensed with the California Contractors State License Board (CSLB).
Step 5: Review the Adjuster's Scope of Loss
After the adjuster's visit, you'll receive a scope of loss — a document detailing what the insurance company is willing to cover and at what cost. Review this carefully. If your contractor's estimate is higher, or if the adjuster missed damage, you can and should submit a supplemental claim with documentation.
This is where having a contractor who understands insurance repair work is invaluable. We help homeowners navigate this process regularly.
Step 6: Authorize Repairs and Begin Work
Once the scope is agreed upon, authorize your contractor to begin. In California, contractors are prohibited from accepting payment from you in advance beyond 10% of the contract price or $1,000, whichever is less. Be wary of any contractor asking for large upfront payments on insurance work.
What About Mold?
Water damage and mold go hand-in-hand in Southern California's climate. If water has been sitting for 24–48 hours or more, mold growth is likely — especially in wall cavities, under flooring, and in any area with limited airflow. Mold remediation is typically covered under homeowner's insurance when it results from a covered water loss, but it must be properly documented as part of your claim.
