Garbage Disposal in Brentwood, CA

A new garbage disposal installed in the Brentwood area costs $250–$500, including the unit and labor. Repair of an existing disposal costs $150–$250. We recommend InSinkErator or Waste King for reliability.

Replace your disposal if it jams frequently, makes grinding or humming noises without working, leaks from the bottom (seal failure), takes longer than usual to grind food, or produces persistent odors despite cleaning. Most disposals last 8–12 years, so age alone is a good indicator.

If you have basic plumbing skills and your sink is already wired for a disposal, a DIY swap can take 1–2 hours. However, new installations requiring electrical wiring or plumbing modifications should be done by a licensed professional. Incorrect installation can cause leaks, electrical hazards, or void your warranty.

For most Brentwood households, we recommend a 1/2 HP InSinkErator Badger (budget) or a 3/4 HP InSinkErator Evolution (mid-range). Families that cook frequently should consider a 1 HP model. Waste King is also a reliable and affordable alternative. Higher horsepower models jam less and last longer.

Replacing an existing garbage disposal takes 30–60 minutes. A new installation where no disposal previously existed takes 1–2 hours because it may require electrical wiring and plumbing modifications. We handle all the work including testing and cleanup.

Avoid putting grease or oil, fibrous vegetables (celery, artichokes), bones, coffee grounds, pasta or rice (they expand), egg shells, fruit pits, and non-food items down your disposal. These items cause jams, dull the blades, and contribute to drain clogs — the most common plumbing call in Brentwood kitchens.

A humming disposal usually means the motor is running but the flywheel is jammed. Turn off the disposal, unplug it or switch off the breaker, and try using an Allen wrench in the bottom reset hole to manually free the flywheel. If this doesn't work, the motor may be burned out and replacement is needed.

Run cold water for 15 seconds before and after each use, grind citrus peels monthly for freshness, use ice cubes to clean the blades, and avoid leaving food waste sitting in the disposal. For persistent odors, pour a half cup of baking soda followed by vinegar, let it fizz for 10 minutes, then flush with cold water.

Most quality garbage disposals come with manufacturer warranties of 2–8 years depending on the model. InSinkErator offers up to 7-year warranties on their Evolution series, and Waste King offers up to 8-year warranties on some models. We also provide a 1-year labor warranty on our installation work.
