How much does a garbage disposal replacement cost in the Bay Area?

A standard swap usually lands between $200 and $450 installed. That covers a half to three-quarter horsepower unit, the mounting hardware, and labor. A higher-horsepower or sound-insulated model adds another $80 to $200 on the unit. If the existing mount and drain plumbing are sound, the labor side is quick. After the $75 diagnostic, credited to the job, you get a written repair-or-replace call and the price before any work starts.

Is it worth repairing a garbage disposal or should I replace it?

Most disposal failures are not worth a repair. A jam, a tripped reset, or a stuck plate is a free fix you can often do yourself. But a leaking shell, a dead motor, or a cracked grinding chamber means the unit is done. Disposals are sealed assemblies, so parts-level repair rarely pencils out. If the motor or housing has failed, replacement is the call.

How long does a garbage disposal last?

A typical unit runs 8 to 12 years. Cheaper builder-grade models can quit in 5 to 7. Past the decade mark and leaking or humming without a grind, plan on a replacement rather than chasing a fix.

Why is my garbage disposal humming but not spinning?

A hum with no grind means the motor has power but the plate is jammed. Turn the disposal off, then use the hex wrench that came with the unit, or a 1/4-inch Allen key, in the slot on the bottom center to free the plate by hand. Press the red reset button underneath, then test. If it still only hums, the motor is likely done and the unit needs replacing.

Do you charge for a diagnostic?

Yes, $75, credited to the repair or replacement when you book the work. You only pay the diagnostic on its own if you decide not to move forward. After the visit you get a written repair-or-replace call and the price.

Garbage Disposal Replacement Cost and When to Swap It

What a replacement actually costs

Across the Bay Area, a straightforward disposal swap runs $200 to $450 installed. Here is roughly how that breaks down:

The unit: a half-horsepower builder-grade model (think InSinkErator Badger 5) is around $90 to $130. A three-quarter or one-horsepower sound-insulated unit runs $150 to $350.
Labor: if the mount, electrical, and drain are sound, the install is fast. Most of the labor is in the connection, the test, and checking for leaks.
Extras: a corroded drain elbow, a failed mounting assembly, or a missing outlet adds parts and time. Anything like that shows up in the written call after the diagnostic, not as a surprise on the invoice.

More horsepower is not always the right buy. A three-quarter-horsepower unit handles a normal household fine and grinds quieter than a base model. One horsepower only matters if you run heavy food waste daily.

Fix it or replace it

Not every disposal problem needs a new unit. Here is the honest split.

Worth fixing, often free, often DIY:

Jammed plate. A hum with no spin means something is stuck. Cut the power, free the plate with the hex wrench in the bottom slot, hit reset, and test.
Tripped reset. No sound at all? Press the red button underneath. One that keeps tripping has an electrical or motor issue.
No power. Check the switch, the outlet, and the breaker before you assume the disposal is dead.

Time to replace:

Leaking from the body or bottom. A crack in the grinding chamber or a failed seal is not a repair. The shell is a sealed assembly.
Dead motor. If it resets, the plate is free, and it still only hums, the motor is done.
Persistent leaks after re-seating. Flange and drain leaks can sometimes be resealed. Leaks from the unit itself cannot.
Age plus a new failure. Past 8 to 10 years with any of the above, replace it.

The rule we use: disposals are cheap relative to labor, so once the motor or housing fails, a swap beats a parts chase.

Two-minute checks before you call

Many “broken” disposals are a quick fix.

Power off at the switch. Never reach into a disposal with power on.
Press the reset button on the underside.
Free the plate with the hex wrench in the bottom-center slot. Work it back and forth until it spins freely.
Clear the chamber of any visible obstruction with tongs, never your hand.
Restore power and test with cold water running.

If it hums without grinding after all that, or you see water under the unit, stop. The motor or housing is the problem and it needs swapping.

How much does a replacement cost? A standard swap runs $200 to $450 installed. Higher-horsepower or sound-insulated units add $80 to $200. You get the number after the $75 diagnostic.

Is it worth repairing? Usually not. Jams and trips are free fixes. A leaking shell or dead motor means replace, since disposals are sealed assemblies.

It hums but will not spin. What is wrong? The plate is jammed. Cut power, free it with the hex wrench in the bottom slot, press reset, and test. Still humming means a dead motor.

Do you charge a diagnostic fee? $75, credited to the repair or replacement when you book the work.
