California Homeowner Water Damage Response

First Actions When Water Enters Your California Home

If you can safely stop the water—such as turning off a leaking washing machine valve—do so. For widespread storm flooding, wait for conditions to improve before wading into water. Standing water can hide electrical shock risks and sharp debris.

Check for gas odors and structural damage. In post-fire areas, flash floods can happen with little warning, so staying alert to weather alerts and evacuation orders is critical. If you see cracks or hear creaking, leave immediately and call 911.

• Know where your gas shut-off valve is and how to turn it off with a wrench.
• If water is from a burst pipe, shut off the main water valve and open faucets to drain the lines.
• Never step into water that is near outlets or appliances.
• Call 811 before any digging if water has shifted soil, as underground utilities could be exposed.

Common California Water Damage Scenarios

Atmospheric river events often bring steady rain for 24 to 72 hours. Gutters, downspouts, and drainage systems can’t always keep up, leading to water seeping under doors, through windows, and into basements. Flat roofs on older commercial-style homes can pond water and eventually leak.

Post-wildfire debris flows are a uniquely California hazard. Burned slopes can’t absorb rain, so even moderate storms can trigger fast-moving mud that enters homes. Separately, many homes built in the 1950s through 1970s have galvanized steel or copper supply lines that corrode and develop pinhole leaks behind walls or inside slabs.

• Clear gutters and roof drains before the rainy season to prevent overflow.
• If you own a hillside home, monitor storm forecasts and have an evacuation plan.
• Look for unexplained water stains on ceilings or warped flooring as signs of slab leaks.
• After a wildfire, sign up for emergency alerts from your county.

Documenting the Damage and Contacting Your California Insurer

Take photos and videos of all water-damaged areas before you begin cleanup. Capture everything: the water line on walls, soaked furniture, ruined electronics. FEMA recommends keeping a detailed inventory and saving receipts for immediate repairs and alternative lodging.

Report the loss to your insurance company quickly. Understand your coverage and ask specific questions about deductibles and exclusions. If you believe your claim is mishandled, the California Department of Insurance can step in. They offer consumer help and accept complaints against insurers.

• Photograph the exterior of your home if mud, debris, or standing water is present.
• Record appliance serial numbers and the condition of personal belongings.
• Keep a log of all conversations with your adjuster and insurer.
• Contact the California Department of Insurance for questions or to file a complaint.

Hiring Help: Checking Contractor Licenses Through the CSLB

In California, the Contractors State License Board (CSLB) issues licenses for many types of construction work. Water damage restoration contractors often operate under a general building or specialty classification. You can verify a license online and check for any disciplinary actions or complaints.

A CSLB license confirms the contractor has met experience, testing, and bonding requirements. Still, you should ask for a current certificate of insurance, and never hire based on a low bid alone. Demand a written contract that details moisture measurement protocols, the scope of drying, and a payment schedule.

• Visit the CSLB website and enter the contractor’s license number to verify status.
• Be wary of contractors who ask for full payment upfront or pressure you to sign quickly.
• Get multiple bids and compare what each includes in their drying and repair plan.
• Confirm that any subcontractors also hold the necessary licenses.

Drying, Mold Prevention, and California Recovery Resources

EPA guidance highlights removing water quickly and drying all materials as the primary mold prevention steps. California’s climate varies, but in damp coastal areas or after prolonged rain, dehumidifiers are essential. Materials like drywall and carpet that were soaked for more than two days generally need removal.

The California Governor’s Office of Emergency Services (Cal OES) is the main agency for disaster recovery information. They coordinate with FEMA and local governments to provide resources and assistance after declared disasters, including flooding and mudslides.

• Run dehumidifiers and fans until moisture meters read acceptable levels.
• Remove baseboards and check wall cavities with a probe meter.
• Dispose of any items contaminated by mud or floodwater from outside.
• Check the Cal OES website for emergency declarations and recovery assistance programs.
