Companies are listed when their Google rating is 4.5 or higher. When a current Yelp listing for the same business is on file, we combine both ratings, weighted by review count, and it must still be 4.5 or higher. Ratings belong to Google and Yelp, separate from reviews of TrustedLocals jobs.
A listing is not an endorsement. You can also browse other listed qualifying companies. Directory listings do not grant a partner slot or change where a TrustedLocals request is routed. Website and call links contact a business directly, outside TrustedLocals request routing.

First, shut off the water. If you know which fixture is leaking, close its valve: sinks and toilets normally have one underneath or behind them, though tubs and showers often do not, and in older homes some are missing or seized. If you cannot find it, or water is coming through a ceiling or wall, close the main valve where the supply enters the home, often on the front wall or in the garage. The valve in the meter box at the street belongs to the water utility and may need a meter key.
If you smell gas anywhere, do not touch light switches, phones or anything electrical. Leave the home, then call the gas utility or 911 from outside. Do not turn the gas back on yourself; the utility or a licensed plumber does that after the leak is fixed.
Then limit the damage. If water is near outlets or coming through a light fixture, turn off power to that area at the breaker panel, but only if you can reach the panel without standing in water or touching anything wet; otherwise leave it and tell the crew. Move belongings out of the water and take photos. Water that has soaked into floors, walls or cabinets, or that came from a drain or sewer, needs a restoration company as well as a plumber. Sewage is Category 3 water under the industry standard, and porous materials it touched, such as drywall, carpet and pad, usually have to be removed.
Emergencies in Los Angeles homes include corroded supply pipes, failed flexible hoses under sinks and behind toilets, leaks in pipes under a concrete slab, sewer backups from tree roots or collapsed clay pipes, and failed water heaters. A camera inspection of the sewer line shows whether a backup is a one-off blockage or a broken pipe, and trenchless repair can often replace a line with far less digging, through access pits at each end instead of a trench across the yard.
Plumbers in California hold a C-36 license from the Contractors State License Board. The record at cslb.ca.gov shows whether it is active, bonded and carries workers' compensation. Water heater replacement and sewer line work need a permit from your city's building department; in the City of Los Angeles that is the Department of Building and Safety. The contractor normally gets the permit and arranges the inspection; ask to be sure.
Ask for the after-hours call-out terms before anyone is sent out; a good company states them up front. Get what they will do in writing before work starts. For anything beyond a simple fix, ask what the alternatives are, for example replacing a failing pipe instead of patching it again.

A plumber repairs the leak; restoration dries and cleans affected floors, walls and cabinets.
