"I am so happy with the services provided by TruePro Home Services! I have a very old oven that I truly believed would need to be replaced. But, Yury came on time, diagnosed the issues, and had the parts with him to do the repair the same day. My oven is now in perfect working order. Highly recommend!"

"Our LG Front Loading washer wasn't draining. I contacted Simon the next day. He had the part on his truck and came by within 30 minutes, and had it up and running super fast! Thank you Simon for your punctuality, honesty and great value. See you next time!"

"Wonderful and top notched care! They were able to meet my same day expectation to get a washer and dryer hooked up in a new house. He was attentive, thoughtful and explained it all as well. I would highly recommend their service!"

5-star rated

$75 – $300

Average repair cost

Garbage disposal repairs cost between $75 and $300 for most problems. Jams and resets are on the low end. Motor failures and housing leaks often mean replacement rather than repair. Disposals are relatively inexpensive appliances, so the repair-vs-replace decision comes up faster than with other appliances.

Repair Cost Breakdown

Repair	Cost Range	Notes
Jam clearing and reset	$75 – $150	A jammed disposal hums but the blades do not spin. The tech uses an Allen wrench to free the impellers and resets the unit. This is the most common disposal service call.
Splash guard replacement	$75 – $135	A worn splash guard lets food and water splash back up through the drain. The rubber baffle costs $5 to $15. Labor is the main cost.
Electrical switch or wiring repair	$100 – $200	A disposal that does nothing at all may have a wiring problem or a dead wall switch. The switch costs $5 to $20. Wiring issues take longer to trace.
Leak repair at sink flange	$100 – $225	The most common leak point is the mounting flange where the disposal meets the sink. The plumber's putty seal or mounting ring fails over time. Parts cost $10 to $30.
Leak repair at discharge pipe	$100 – $200	A leak from the side discharge pipe means the gasket or connection has failed. The gasket costs $5 to $15. The pipe fitting may need tightening or replacement.
Dishwasher connection repair	$75 – $175	The hose from the dishwasher connects to the disposal. A loose clamp or cracked connector causes leaks under the sink. Parts cost under $15.
Full disposal replacement (standard 1/2 to 3/4 HP)	$150 – $350	A standard InSinkErator or Waste King unit costs $75 to $175. Labor for removal and installation takes 45 minutes to 1.5 hours.
Full disposal replacement (premium 1 HP+)	$275 – $500	High-powered units like the InSinkErator Evolution Excel cost $200 to $350. These handle tougher waste and run quieter. Installation labor is the same as standard units.

Factors That Affect Cost

Horsepower rating

Disposals range from 1/3 HP to 1+ HP. Higher HP units cost more to replace but are less prone to jams. A 1/3 HP unit costs $60 to $100. A 1 HP unit costs $175 to $350.

Septic system compatibility

Homes with septic systems need septic-rated disposals. These models include additional grinding stages and cost 15 to 25 percent more. Not all brands offer septic-compatible units.

Sink and plumbing configuration

Some installations require adapters for non-standard sink drain openings. Double-bowl sinks may need additional plumbing work. Older homes sometimes need electrical upgrades to support the disposal.

Repair vs. replacement threshold

Disposals are cheap enough that many repairs approach the cost of a new unit. A $200 motor repair on a $150 disposal does not make sense. The low replacement cost makes this appliance unique.

Labor rates

Southern California service rates are $90 to $150 per hour. Most disposal repairs take 30 to 60 minutes. A full replacement takes 45 minutes to 1.5 hours depending on the installation complexity.

Repair vs. Replace

Garbage disposals last 8 to 12 years. Because they cost $75 to $350 for a new unit, the replacement math is different from other appliances.

✅ Repair when…

•The problem is a jam, reset, or splash guard replacement under $150.
•The leak is at a connection point, not from the housing itself.
•The disposal is less than 4 years old and under warranty.
•The fix is an electrical switch or wiring issue, not the motor.

❌ Replace when…

•The motor has burned out or seized permanently.
•The housing is cracked or leaking from the body.
•The unit is over 8 years old and needs a repair over $125.
•The repair cost exceeds 50 percent of a new unit with installation.

The 50% Rule

For disposals, the 50 percent rule kicks in fast. A standard unit installed costs $150 to $350. Any repair over $100 to $175 on a unit more than a few years old usually means you should replace the whole thing.

Garbage Disposal Repair Cost — FAQ

The impellers are jammed. Turn off the disposal and use the Allen wrench hole on the bottom to manually free the blades. If that does not work, a tech can clear it for $75 to $150. Do not put your hand inside the disposal.

Most disposals last 8 to 12 years with normal use. Higher HP models tend to last longer because they jam less often. Running cold water during use and avoiding fibrous foods extends the lifespan.

Repair if the fix is under $125 and the unit is under 5 years old. Replace if the motor is dead, the housing is cracked, or the repair exceeds half the cost of a new installed unit. A standard replacement runs $150 to $350.

If you have basic plumbing skills and the electrical outlet is already in place, DIY is possible. But improper installation causes leaks and electrical hazards. TruePro installs new disposals for $150 to $500 total, including the unit. Call 877-378-3111.

Yes. Most building codes require a dedicated 15 or 20 amp circuit. If your kitchen does not have one, an electrician needs to add it before installation. This adds $150 to $300 to the project.
