A broken garbage disposal can stall your whole kitchen sink and leave water on the cabinet floor. Fast garbage disposal repair gets the unit grinding again, clears the backup, and stops the leak. Whether the motor hums, the unit is dead, or it drips under the sink, a licensed plumber can diagnose it and fix it the same day.

What Garbage Disposal Repair Covers
A pro handles far more than a stuck flywheel. Common work includes freeing a jammed grinding chamber, replacing a failed motor or reset switch, swapping a leaking sink flange or gasket, clearing a clog between the disposal and the trap, and rewiring a bad switch or outlet. If the unit is past saving, the same visit usually covers a like-for-like replacement.
Common Garbage Disposal Problems We Fix
Most calls trace back to a short list of symptoms. The table maps each one to a likely cause and whether to try a fix or call a pro.
| Symptom | Likely cause | Try yourself or call a pro |
|---|---|---|
| Hums but won't spin | Jammed flywheel or seized motor | Reset and unjam first, then a pro |
| Dead, no sound at all | Tripped reset, GFCI, or burned-out motor | Reset, then a pro |
| Leaking from the top | Worn sink flange or putty seal | Pro |
| Leaking from the bottom | Cracked internal seal or housing | Replace, pro |
| Slow drain or backup | Clog in the trap or drain line | Pro |
| Loud rattle or grinding | Foreign object or broken impeller | Pro |
Try This First: Reset and Unjam Safely
Two quick checks fix a surprising number of units before a plumber arrives. First, kill the power. Flip the wall switch off and unplug the disposal or shut off its breaker. Never put your hand in the chamber. To reset, press the small red button on the bottom of the unit, then test it. To free a jam, fit a 1/4-inch hex wrench into the center socket on the underside and rock it back and forth until the flywheel turns freely. Restore power, run cold water, and test. If it still hums, trips, or leaks, book a repair. Never reach into the chamber, and skip chemical drain cleaner in a disposal, since both do more harm than the original fault.
Repair or Replace Your Disposal
A disposal usually lasts about 8 to 12 years. Below that age, most faults are worth repairing, since jams, a bad switch, and worn seals are cheap fixes next to a new unit. Past a decade, or if the housing leaks from the bottom, replacement is the smarter call. Frequent resets, visible rust, and grinding that keeps stalling all signal a motor on its way out.
What Affects the Cost
Cost comes down to parts, labor, and how involved the fix is:
- The fault itself. A reset or unjam is minor, while a motor swap or a bottom-housing leak costs more.
- Repair versus replacement, plus the horsepower and brand of any new unit.
- Wiring work, such as a failed switch, outlet, or GFCI, which adds time.
- Access under the sink, including a corroded flange or seized fittings.
- After-hours or same-day emergency response.
A good plumber quotes an upfront, flat-rate price before work starts. If the backup runs past the disposal, ask about professional drain cleaning or have them clear a clogged kitchen drain on the same visit.
Plumber or Electrician: Who Do You Call?
This one trips people up, so here is the short answer. If the trouble is the disposal itself, a jam, a leak, a clog, or a worn motor, call a plumber. They handle the unit, the seals, and the drain connection. Call an electrician only when the fault is clearly in the home wiring, like a dead circuit that knocks out other outlets too. Most disposal repairs, including the reset switch and the unit's own cord, fall to a plumber. If water is dripping near the wiring, treat it as urgent and get a 24 hour plumber out fast. A steady under-sink drip that is not the disposal may instead point to water leak repair under your sink.
Brands We Service
We repair and install every major brand, including InSinkErator, Moen, Waste King, GE, and KitchenAid. Continuous-feed and batch-feed models are both fair game, and the truck carries common reset switches, flanges, and seals so most repairs wrap up in one trip.
Garbage Disposal Maintenance Tips
A few habits keep a unit grinding for years. Run cold water before, during, and a few seconds after each use. Feed scraps in slowly rather than all at once. Skip grease, bones, and fibrous waste like celery or onion skins. Grind a handful of ice cubes now and then to knock buildup off the ring, and drop in a few citrus peels to cut odors.

Common questions
Why is my garbage disposal humming but not spinning?
A hum with no spin almost always means the flywheel is jammed or the motor has seized. Cut the power, then turn the center socket on the underside with a 1/4-inch hex wrench to free it. If it still hums, the motor likely needs replacing.
How do I reset a garbage disposal?
Turn off the wall switch, then press the small red reset button on the bottom of the unit. Run cold water and test it. If it trips again right away, the unit needs a closer look.
Should I repair or replace my garbage disposal?
Repair a unit under about 8 years old with a simple fault like a jam, bad switch, or worn seal. Replace one that leaks from the bottom, is over a decade old, or keeps stalling and tripping.
Who fixes garbage disposals, a plumber or an electrician?
A plumber handles the disposal, its seals, and the drain connection, which covers most repairs. Call an electrician only if the wider circuit is dead and other outlets are affected too.
How long does a garbage disposal last?
Most units run 8 to 12 years with regular use. Cold water when grinding, avoiding grease and fibrous scraps, and the occasional ice-cube cleaning all help it reach the high end.
