Flood Damage Cleanup in Huntington Beach
King tides, high surf and winter storms can push seawater and runoff into homes in Huntington Harbour, Sunset Beach and other low-lying parts of the city. Floodwater is treated differently from a pipe leak. Here is why, and what to do.

- Tidal and storm flooding
- Saltwater and Category 3 water
- Huntington Harbour & Sunset Beach
Floodwater from a tide, storm or flooded street is treated as contaminated Category 3 water. Stay safe, keep power off in wet areas, photograph the high-water line and call your flood insurer. A restoration crew removes the water, takes out soaked porous materials like carpet and lower drywall, cleans and disinfects, and dries the structure before rebuilding.
Huntington Beach lives with the ocean on two sides of many neighborhoods. Homes along the Huntington Harbour channels, in Sunset Beach and near the Bolsa Chica wetlands sit only a few feet above high tide. When a very high tide lines up with big surf or a winter storm, water can come up through storm drains and over low walls.
The cleanup is not the same as a burst pipe. Seawater and runoff carry contaminants and salt, and that changes what can be saved.
What to do when floodwater gets in
- Stay out of moving water and don't drive through flooded streets. Six inches of moving water can knock you down.
- Turn off power to flooded areas at the panel only if you can reach it while standing somewhere dry. Otherwise call SCE or an electrician.
- Don't use a water heater, furnace or appliances that sat in water until a professional checks them.
- Photograph the high-water line on walls, plus every damaged item, before cleaning.
- Wear boots and gloves. Treat floodwater as contaminated.
- Call your flood insurer if you have a policy, then get water removal and drying started.
Tidal and storm flooding on the Orange County coast
King tides and high surf
Very high tides push seawater up through storm drains and over low seawalls and beaches. In late October 2026, water flooded streets in Huntington Harbour and Sunset Beach, crews pumped water off Bayview Drive, and PCH was partly closed between Warner Avenue and Anderson Street.
Heavy rain and runoff
During winter storms, street drains back up and water pools against garage doors and low entries. In November 2025 a storm flooded neighborhoods on the north side of the city, according to ABC7.
Storm at high tide
The worst cases happen when heavy rain arrives at high tide. Drains can't empty into the harbor or ocean, so water backs up into streets and yards.

Why floodwater is handled differently
Restoration contractors classify water using the IICRC S500 standard. A burst supply line is clean (Category 1) water. Water that comes in from outside, whether from a tide, a storm or a flooded street, is treated as Category 3: it can carry sewage, fuel and debris.
- Porous materials usually come out: carpet and pad, the lower part of drywall, insulation and particleboard cabinet bases.
- Salt stays behind: salt left in drywall and wood keeps attracting moisture, so a salt-soaked wall can stay damp or stain again later.
- Metal corrodes: water heaters, appliances, HVAC equipment and electrical parts that sat in seawater may need replacing.
- Disinfection: hard surfaces are cleaned and disinfected before anything is rebuilt.
Is this a same-day job?
Get someone out today when
- Water got past the garage into the living space.
- Drywall, carpet, cabinets or a water heater got wet.
- Water sat for more than a few hours or smells like sewage.
- Another high tide or storm is forecast and the home is still open or wet.
Probably safe to book for later when
- Water only reached the driveway or the garage slab and nothing stored got wet.
- You rinsed and dried the concrete and the walls are dry to the touch and to a meter.
On the fence? Pick the first column. Moisture you can't see keeps spreading while you decide.
Who pays when the water came from outside?
- Flood insurance: needed for rising water, tide and surge. FEMA's NFIP program covers the building and contents up to set limits.
- Homeowners policy: generally excludes flood, but may cover water that came in through a storm-damaged roof or window.
- Renters: the landlord handles the building. Contents need your own flood coverage.
- Condos and Harbour HOAs: the association's policy may cover common areas and structure. Ask the manager.
Details the crew will need
- Whether the water was tide, storm runoff or both, and when it came in.
- How high it got inside (inches up the wall) and which rooms.
- Whether the water heater, HVAC or electrical equipment sat in water.
- Whether you have flood insurance and a claim number.
Ask how they will handle salt-soaked drywall and insulation, and get that in writing.
Flood cleanup questions
Is tidal flooding covered by homeowners insurance?
Usually not. The California Department of Insurance states that homeowners policies do not cover flood damage, and seawater from a high tide counts as flood. Flood coverage comes from a separate policy, such as one through FEMA's National Flood Insurance Program.
Why is saltwater flooding worse than a pipe leak?
Water from outside carries sewage, oil and street debris, so it is treated as Category 3 (black) water. Salt also stays in drywall and insulation after it dries and keeps pulling moisture from the air, which can bring back staining and odor. Most porous materials it touched are removed, not dried.
Can I hose out the garage after a high tide?
Rinsing salt off concrete is fine once the water is gone. But if water got into drywall, cabinets, a water heater or stored boxes, those need more than a rinse. Have the water heater and any electrical equipment checked before using them.
Where do I get sandbags in Huntington Beach?
The city lists the Corporate Yard at 17371 Gothard Street, open weekdays 8 a.m. to 4 p.m., plus seasonal sites at the Edison Community Center (21377 Magnolia Street) and Warner Fire Station (3831 Warner). Bring a shovel. The limit is 20 bags per household, and the sites are for Huntington Beach and Sunset Beach residents.
Do you cover flood damage cleanup elsewhere in Orange County?
Not at the moment. This site and its referral line cover Huntington Beach and Sunset Beach only. Newport Beach and Seal Beach saw the same October 2026 tides, but we can't connect callers there yet.
How long does flood cleanup take?
Removal and drying often take about a week for a single floor, then repairs follow. Larger floods, or homes where insulation and lower walls must come out, take longer.
Before and after the next tide
Floodwater got into your home?
Salt and contaminants don't dry out on their own. Wet drywall and insulation need to come out within a day or two.
