When a disposal hums but will not grind, leaks under the sink, or does nothing at all, a plumber can usually fix it in one visit. Fixr's national guide puts a repair at about $65 to $150 and a new unit installed at about $300 to $600, with Los Angeles rates not covered. From the home page you can also reach every other service we arrange in Santa Monica and the Westside.
This page covers the kitchen first (repair, replacement, first-time installs), then shower leaks and fixtures, since the same kind of plumber handles both. The price arrives on paper before anyone picks up a tool.
Why has my disposal stopped working?
Four faults account for most calls: a jam from a stuck object, a tripped overload reset, a leak at a seal or the sink flange, and a failed motor. The first two are cheap and quick. A split casing or a dead motor normally ends in a new unit, because the repair costs close to what a replacement does.
Here is how each shows up:
- Hums but the blades do not move. Something is wedged between the grinding plate and the shredder ring. Think peach pits, bottle caps, a stray spoon.
- Silent, no hum. The unit may have tripped its internal overload, there may be no power, or the wall switch or outlet may have failed.
- Water on the cabinet floor. The leak could come from the flange ring in the sink basin, the side outlet fitting, the dishwasher hose, or a crack in the casing. Find the wet spot with a dry paper towel.
- Grinds, but the sink drains slowly. The clog sits downstream, in the trap or kitchen line. Start with clearing a blocked disposal drain.
Safe first checks: turn the power off first and never put fingers in the chamber. Many units have a hex socket on the underside that a wrench can turn to free a jam, and a small reset button nearby. If neither helps, or if there is any smell of burning, stop and call.
What does disposal repair or installation cost in Santa Monica?
Fixr's national guide lists a repair at about $65 to $150 and an installed disposal at about $300 to $600, averaging $500. A first-time install runs $300 to $450 with a plug-in unit and $400 to $600 when it is hardwired, and a new outlet adds $120 to $200. Those are national figures, not Santa Monica rates, so the written quote sets your price.
What moves a quote: the horsepower of the unit, whether the old mounting ring matches, a dishwasher hookup, and any electrical work. Fixr's unit-only figures climb with motor size, from about $50 to $150 for a one-third horsepower model to $200 to $400 for a one horsepower model.
One California note. California requires a contractor license for work of $1,000 or more in labor and materials, and a home improvement down payment is capped at 10 percent of the price or $1,000, whichever is less.
How is a new disposal put in?
Out comes the old unit. The plumber scrubs the flange seat, hangs the replacement on a new mounting ring, reconnects the drain and dishwasher hose, tests under running water, and checks the power. A swap takes about an hour. A first-time install adds the electrical connection and sometimes a new trap.
Your side of the checklist:
- Choose the unit. A bigger motor handles tougher scraps and costs more. Pick a mid-range model unless you cook heavily.
- Ask who supplies it. Parts brought by the plumber are normally marked up; supplying your own can lower the bill.
- Empty the cabinet beneath the basin; the plumber needs room to lie down.
- Confirm the dishwasher setup. The dishwasher usually drains into a side port on the disposal. The guide to garbage disposal installation walks through the connection.
If the unit is wired to a switch that never worked, a plumber may flag it for an electrician instead of guessing.
Can the same plumber fix a leaking shower?
Yes. Shower calls are mostly worn cartridges, failed seals on a valve, or a leaking drain, and each is a distinct fault. A cartridge swap is the smaller job. A full valve replacement costs more, since tile and drywall can come out and then go back, and the written quote sets both prices.
Clues that tell them apart:
- Showerhead dribbles after shutoff. Usually the cartridge or valve seat. The shower faucet repair steps show the usual order.
- Discolored plaster beneath the bathroom. Water may be running inside the wall or past the shower pan. Phone a plumber and read about shower leaks before tearing out any tile.
- Hot water that never gets hot. The cause could be a mixing valve or the heater itself. Check no water from the hot faucet first.
Drips cost money too. EPA says the average household's leaks waste more than 9,300 gallons a year, and a showerhead is an easy fixture to blame.
What other sink and faucet jobs come with the visit?
A plumber already under your sink can also deal with a worn faucet, a seeping supply connection or poor flow. Mention these when booking so the right parts are loaded up, and the time on site gets used once instead of needing a second appointment later in the week.
Related pages to check first:
- Dripping faucets, the common fault in kitchens and baths.
- Leaking pipe under a sink when the cabinet floor is wet.
- Faucet installation costs if you are swapping the whole fixture.
- Low flow at the kitchen tap, most often a clogged screen at the spout tip or a stop valve left part closed.
- Leaky outdoor spigot for hoses that drip when attached.
The stop valves under a sink are a common weak point, so the plumber will test them while the cabinet is open.
Common questions
What is a realistic duration?
A jam or reset is a quarter-hour. A leak at a seal runs under an hour. Swapping one unit for another fills an hour or two; a first install with wiring takes longer. The plumber should name a window after seeing the sink and the power supply, and tell you if the estimate has changed before they proceed.
What belongs on my list of questions?
Ask what is included: the unit, haul-away of the old one, and a test under running water. Learn if the price is fixed or billed hourly, whether an electrician must join, and what the work is covered for. Confirm the license number at the state board's online lookup before any deposit changes hands.
Do I have to wait around at home?
Be there when the plumber arrives, to show the sink and switch, and when the job ends, to run the unit and approve it. You can leave in between if a trusted adult covers the door. A renter should also tell the landlord before booking.
Can I use a drain cleaner in a disposal?
Avoid it. Chemical cleaners sit in the trap and can damage rubber seals and metal parts, and they splash back on whoever opens the pipe later. Cold water, a few ice cubes, or the hex-key reset are safer. If the sink is still clogged, a cable machine from a plumber clears the line.
