Clogged gutters and street flooding in Claremont
The city's stormwater page says leaves and clippings pushed into gutters clog catch basins and can raise the risk of street flooding. The same goes for your own roof gutters and yard drains. When they clog, water goes over the edge and down the wall or pools against the foundation.
Claremont also runs a Downspout Disconnect program and links guides on rain barrels, dry wells and bioswales. Those can help, but redirected roof water has to land away from the house. Ask the city before you reroute a downspout, and check that the new path slopes away from your walls.
Where roof and yard water goes wrong
Most storm-related interior damage starts outside. Here is where we see the path break down and what a homeowner can check.
| Spot | What happens | What to check |
|---|---|---|
| Roof gutters | Debris dams the channel and water spills behind the fascia | Clear leaves before each rainy season |
| Downspout outlet | Water dumps next to the slab or crawl space vent | Extend or redirect it away from the house |
| Yard low spot | Runoff pools and seeps toward a door threshold | Regrade or add a drain, ask the city first |
| Street catch basin | Clogged inlet backs water into the gutter line | Keep clippings out of the street |
| Attic or roof flashing | Rain finds a gap and soaks insulation and ceiling drywall | Look for stains after a storm |
Storm water that enters the house is usually Category 2 or 3 and needs more careful removal than a clean supply leak.
When water is spreading in Claremont
If water is coming in, work on the source and the main valve, then call. Our dispatch line answers around the clock, whether it is midnight or noon.
The crew pumps first with extraction units, then pulls wet baseboards and cuts back soaked drywall where needed. Anything that stays wet longer than a few days invites mold. The emergency water removal page explains the equipment and steps in more detail.
If water is still spreading
Work through these, skipping anything unsafe, and keep your phone dry for photos.
- Find and close the mainIt is usually near the street side of the house or by the water heater. Turn it fully closed and open one faucet to relieve pressure.
- Breakers only if drySwitch off power to wet rooms only if the panel is dry and you can reach it standing on dry floor. If not, call the utility or 911.
- Raise the valuablesGet paper, electronics and small furniture up onto counters or beds. Roll up area rugs before they bleed dye into flooring.
- Avoid contaminated waterStorm runoff and sewer water can carry bacteria. Keep kids and pets away and do not wade through it barefoot.
- Ring the 24/7 lineTell the dispatcher where the water entered and how deep it is. Describe the floors, walls and any items affected.
Call now and a crew can be sent day or night. Photos help, but do not delay the call to take them.
Water, sewer and permits in Claremont
Claremont states that it does not own or run the water service. Golden State Water Company does, and Three Valleys Municipal Water District, based in Claremont, is a wholesale supplier. For no-water or street-meter problems, call the provider and not the city.
The city's sewer page says main lines are maintained by its Community Services Department and property owners maintain their laterals. That split matters in a backup: if the whole street is slow, tell the city, and if only your fixtures back up, the lateral is probably yours.
Permits go through the Building Division at 207 Harvard Avenue. California requires a contractor licence once labor and materials reach $1,000 or a permit is needed. Use the CSLB site to verify any contractor, including for water damage repair.
Flood risk and what to look up for your address
The city has a Local Hazard Mitigation Plan approved by FEMA, and you can ask the city for it. We cannot tell you your flood zone from here, so check the FEMA flood map for your address.
Flood is usually excluded from standard homeowners policies, so a separate flood policy is a conversation for your insurer. If water has already come in, read our mold remediation page before you tear out anything that may be moldy.
Where we send crews in Claremont
Claremont water damage questions
Yes. Our dispatch line answers 24 hours a day, every day, including nights and holidays. Arrival depends on conditions and on how many calls are ahead of yours, so we do not promise a time. Start with the main valve while you wait.
We serve ZIP 91711, which the city uses on its published addresses, including the Building Division on Harvard Avenue. If your mailing address shows something else, call and give us the street address. We will tell you plainly whether we can reach you.
Yes. Overflow runs behind the fascia, down walls and against the foundation, and it can soak insulation and drywall without leaving puddles. Clean gutters before the rainy season and check that downspouts empty away from the house.
The city says it does not run water service, so call Golden State Water Company if the leak is at the street or meter. If the leak is on your side of the meter, shut your main valve and call a restoration crew and a plumber.
Per the city, it maintains the main lines and property owners maintain their laterals. If neighbors are affected too, report it to the city. If only your home backs up, expect the lateral to be your responsibility, and treat the water as contaminated.
Flood damage is usually excluded from standard homeowners policies. Ask your insurer how your policy defines flood and whether you hold separate flood coverage.
Possibly. Ask the Claremont Building Division what your scope requires. Any contractor on a job of $1,000 or more, or one that needs a permit, must hold a California licence.
