What to do before anyone arrives
- Gas smell or smoke: get out, call 911, and then reach your gas utility from outside, using the numbers lower on this page.
- Stay out of standing water that reaches outlets, cords or the panel. If the panel is dry and you can get to it without stepping in water, switch off power to the wet rooms.
- Close the main valve or the fixture valve, and carry small valuables and electronics out of the wet area.
- Photograph and film every wet room before you move anything, list what got wet, and hold onto damaged items until the insurer says otherwise.
- Phone your insurer, give the cause as it was, and log each call; CDI's tips for wildfire claimants call that log a claim diary.
- Then request a company on the form and save every receipt. If you can't tell whether the loss is covered, CDI's consumer line is 1-800-927-4357.
Mitigation, drying and rebuild arrive as separate lines
Stopping more damage comes first, with the source shut off and the standing water out. Drying follows, and the structural drying page covers the equipment. The rebuild is the drywall, flooring and framing the water ruined.
Get the extraction and drying scope on paper first, and have the rebuild priced separately. That's the stage where a contractor holding a CSLB license comes in.
How much water damage restoration costs in California (estimates, not quotes)
Our model puts a whole water damage job at $1,400 to $6,150 per job, and no company has quoted that figure. The wage rows show what the nearest federal occupation is paid. Below them, the claims row shows how much of insured home losses water takes, and neither one's a price.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $1,400 to $6,150 per job | Built from 3 national published ranges, adjusted by the California hazardous materials removal worker wage ratio (1.08). No California water, fire or sewage restoration company published a price we could count. Three California mold-inspection firms publish inspection prices, which are not a restoration job and are not used in these rows. Basis: no state company sample (no counted California company price for this job), national estimate only. |
| Hazardous materials removal worker wage, California mean | $29.21 an hour (United States mean: $27.13) | Pay for the nearest federal occupation to a restoration crew (BLS, May 2025). The model uses it to adjust for California; it isn't a charge. |
| Same occupation, California median | $26.98 an hour (middle half of workers: $22.68 to $32.47) | O*NET's reading of the same BLS data, matched to restoration crews by our own inference. |
| Same occupation, Los Angeles-Long Beach-Anaheim and San Francisco-Oakland-Fremont medians | $24.59 and $28.65 an hour | Pay in two large metros, shown beside the statewide median. |
| Insurer water damage and freezing claims, share of insured home losses | 22.6 percent of losses in 2023; 1.6 percent of insured homes a year, 2018 to 2022 | The Insurance Information Institute's figures, drawn from ISO claims data, describe claims and not prices. |
Estimated range. Built from national published ranges (3 sources), adjusted by California's hazardous materials removal worker wage ratio to the US (1.08, BLS May 2025). Not a quote. No California restoration company published a water, fire or sewage price we could count. We have no counted California company price for this job, so the range is our national estimate alone. Full method. Prices as of Oct 23, 2026.
Water categories, and the standard behind them
ANSI/IICRC S500 is the standard for water damage restoration, in its 2021 fifth edition, and IICRC says its consensus body has begun a revision. IICRC sets standards and runs a locator for firms holding its credential. It licenses no one.
Ask each company which water category and class it recorded for your job, and why. The water category explainer turns the answers into questions to ask.
What CDI's guide says a California homeowners policy covers
Sudden and accidental water damage appears in CDI's residential guide as a peril generally covered, while flood, mold and seepage or leaks appear among those generally not. Report the cause as you found it.
The insurer's clock under 10 CCR 2695.7
Once the insurer holds your proof of claim, 10 CCR 2695.7(b) gives it 40 calendar days to accept or deny, and a denial must be in writing with every basis listed. Payment follows within 30 days of acceptance. If it needs longer, (c)(1) calls for written notice of why, repeated every 30 days. Those are the regulation's words as Cornell's LII copy prints them.
If those dates slip, call CDI's consumer hotline at 1-800-927-4357 or file a Request for Assistance on its help page.
Who may adjust your loss for a fee
Nobody may act as a public adjuster in California without a CDI license, and a contract with an unlicensed adjuster is voidable with nothing owed. The contract must use a Commissioner-approved form that states the fee, and you can cancel within three business days. An adjuster also can't take money from, or hold a stake in, a repair or salvage firm that gets work from a claim they adjust. Check a license at cdicloud.insurance.ca.gov/cal/.
When water damage can't wait
- Water is still coming in or standing in a room.
- Water has reached outlets, the panel, a furnace or an appliance.
- Nobody can say where the water came from, or it may be sewage.
- A ceiling sags, a wall bulges, or a room smells musty after a day or two.
- An old stain that has stayed dry, with nothing soft or musty behind it; take a photo for the insurer before anything else.
- A dry cosmetic repair, once the insurer has seen the damage.
Water damage work: contractor licenses and permits in California
CSLB's classification list has no water damage class, no fire restoration class and no mold class, so no CSLB class is named for the drying itself. The rebuild is different. B&P 7048 exempts a project only when its aggregate price is under $1,000, the work is casual and minor, and no building permit is needed. The exemption fails if the person advertises as a contractor or employs someone to do the work.
Rebuilds and repairs permitted from 2026 are plan-checked to the 2025 California Building Standards Code. Ask who pulls the permit, and where. Then look up the contractor's license number on CSLB's lookup.
Ask which licenses your state requires for the work, and check them with your state's licensing office before anyone starts. A credential from a private body, such as IICRC, isn't a license.
Questions people ask
Is mitigation the same job as restoration?
Mitigation covers stopping the source, extracting water and drying, and restoration repairs what the drying couldn't save. Ask for the two scopes separately, so you can see which bill is which.
How long does water damage take to dry in California?
EPA's 24 to 48 hours is the window for drying water-damaged areas and items to prevent mold growth, and it says nothing about how long drying lasts. Ask the company for moisture readings at each visit.
How do I get my insurer to pay for water damage in California?
CDI's guide lists sudden and accidental water damage as generally covered and seepage or leaks as generally not. After your proof of claim, 10 CCR 2695.7 (as Cornell's LII copy prints it) gives the insurer 40 calendar days to accept or deny. If it stalls, CDI's hotline is 1-800-927-4357.
Can a water-damaged room be saved?
EPA says mold can grow on wood, drywall, carpet and furniture wet for over 24 hours, so tell the company exactly when the water arrived.
Is there a California license for water damage restoration?
CSLB lists A, B, B-2 and C classes, and none is named for water damage. IICRC credentials come from a private standards body and aren't a state license.
