Flood water is an emergency from the first minute because it is often contaminated and it moves quickly through a building. The emergency line is open 24/7, so call as soon as it is safe. While you wait, stay out of standing water, keep children and pets away, turn off power only if the panel is dry and reachable, and lift valuables to higher shelves.
This page covers storm and groundwater flooding, basement flooding cleanup and sewage backup cleanup. For clean water from a broken pipe, the emergency water removal page is the closer match.
Water that came from outside or from a drain is different
Flood water is graded as Category 2 or Category 3 in the industry because it can carry soil, bacteria and chemicals. The label matters because it sets what can be dried in place and what must be removed. The standard that trade professionals use for this is ANSI/IICRC S500, and you can ask any company whether its crews follow it.
If you are not sure what kind of water you have, treat it as contaminated until a crew has looked at it. The cost of being cautious is small next to the cost of cleaning mold out of a wall that was dried the wrong way.
| Water type | Common San Pedro cause | Typical handling |
|---|---|---|
| Category 1 (clean) | Supply line break caught fast | Extract and dry in place when materials allow. |
| Category 2 (gray) | Appliance overflow, sump failure, early storm water | Remove padding, clean hard surfaces, dry the structure. |
| Category 3 (contaminated) | Sewer backup, rising storm water, long-standing water | Remove porous materials, clean and sanitize before drying and repair. |
Why San Pedro storms test old buildings
The area gets roughly 14 inches of rain a year, and January through March bring the most. A wet winter after a dry summer is when roof flashing, garage doors, window frames and clogged gutters let water in. Bluff-top properties near Point Fermin Park also deal with ground that can saturate.
The 1929 Sunken City slide is the most famous local example. The first damage reports came on January 2 when a water line broke beneath a hotel on Paseo Del Mar, and the slide was later tied to waves undercutting the cliff and water soaking into a clay layer. The takeaway for homeowners is to watch drainage and downspouts, because water near a foundation does not stay near it.
Flood insurance is a separate policy from homeowners coverage. To see whether your address sits in a mapped flood zone, search the FEMA Flood Map Service Center, and ask your insurer what your current policy says.
Basement flooding cleanup
Basements and lower garage rooms collect water because they sit below the surrounding ground. The usual sources are rain that overwhelms the drain, a failed sump pump, a broken water heater or a pipe that gives way below the main floor. Water in a finished basement soaks carpet, wall bottoms, stairs and stored boxes quickly.
The sequence is steady. The crew pumps out the water, removes wet padding and the bottom of soaked drywall, cleans the surfaces and sets drying equipment. Dehumidifiers matter most in lower levels because the air stays damp longer. Ask the crew about moisture readings in the walls, since a floor can feel dry while the wall cavity behind the baseboard is not.
Restoration is not waterproofing. If water enters through the foundation every winter, a drainage or waterproofing contractor has to fix the entry point or the loss will repeat.
Sewage backup: what to do first
Sewage is a stay-out situation
Raw sewage from a toilet, tub or floor drain is Category 3 water. Stay out of it, keep people and pets away, shut off the water to the house if the toilet keeps running, and call the line. Do not run fans or the HVAC system to move air around.
If the backup appears to come from the street sewer rather than your own line, ask LA Sanitation or your plumber whether the city main is blocked. We handle the cleanup inside the building.
Crews remove contaminated porous materials such as carpet, padding and wet drywall, then clean and sanitize hard surfaces before any drying equipment goes in. Some items cannot be saved, and a good crew will tell you which ones and why before they are removed. The same-day response is offered when available, and after-hours calls are normal for this kind of loss.
What shapes the price of flood work
| Factor | What changes | Why it matters |
|---|---|---|
| Water category | Gray or contaminated | Higher categories need more removal and sanitizing. |
| Depth and area | How much of the building is wet | More area needs more equipment and more drying days. |
| Materials | Carpet, drywall, insulation, wood | Porous materials usually come out after contaminated water. |
| Access | Basement stairs, tight rooms | Difficult access slows pumping and removal. |
| Rebuild scope | Drywall, flooring, paint | Repair is separate and depends on finishes. |
Flood damage is usually excluded from a standard homeowners policy, while sudden water from inside the home may be covered. Check your policy, ask your insurer which one applies and keep photos, moisture readings and receipts together. Nobody can promise an insurance payout, and we do not.
Drying and cleaning for this type of loss are explained further under water mitigation and water damage cleanup, and the crew also works in Wilmington, where a suspected water main break flooded blocks of Avalon Boulevard in 2022.

☎ Call (424) 550-5662Questions about flood damage
Do you handle flood damage emergencies at night or on weekends in San Pedro?
Yes. The emergency line is answered 24/7, and same-day response is offered when available. Storms and backups do not keep business hours, and neither does the line.
Is flood water always contaminated?
Not always, but it should be treated that way until a crew confirms. Rising storm water and drain backups are usually Category 3, while a supply line break is typically clean at first.
Can a flooded carpet be cleaned and kept?
Clean water that is caught quickly can sometimes be dried in place. After contaminated water, carpet and padding are normally removed because they cannot be reliably sanitized.
Does homeowners insurance cover flood damage?
Usually not. Flood damage generally needs a separate flood policy. Ask your insurer what your policy covers and file quickly if you believe you have a covered loss.
Is basement restoration the same as waterproofing?
No. Restoration dries and repairs what the water damaged. Waterproofing stops future entry and is done by a different trade.
