Before you sign
Questions to ask before authorizing garbage disposal service
- 01
Where is the leak originating — sink flange, dishwasher inlet or the housing seam — as a cracked housing cannot be sealed?
- 02
Does the existing mounting assembly match the new unit, or must the sink flange and gasket be replaced too?
- 03
Is the outlet, switch and cord connection within scope, since some disposal work needs a licensed electrician instead?
- 04
Is the motor seized or merely jammed, because clearing a jam and replacing the unit are very different pieces of work?
Before anyone touches a pipe
Verify the license. It takes two minutes.
- Who licenses the work: Contractors State License Board (CSLB).
- Who pulls the permit: the licensed contractor, never the homeowner.
- What to ask for: the license number, the registered name behind it, and an insurance certificate issued to the property address.
Answers first
Garbage Disposal in California — questions homeowners ask
My disposal just hums — is it dead?
Usually not. A hum with no rotation means the flywheel is jammed. Cutting power at the breaker and freeing the flywheel often revives it. A unit that is silent with power on has generally lost the motor or the switch.
What should never go in a garbage disposal?
Grease and cooking oil, fibrous vegetable waste, coffee grounds in quantity, eggshells in quantity, pasta and rice, and bones. Most of these do not damage the motor — they build up downstream and become a drain-cleaning call.
How long do garbage disposals last?
Commonly around 8–12 years depending on use. Once the housing itself is leaking, the unit is replaced rather than repaired.
What warranty applies to the work?
Whatever the contractor offers in writing — PlumberCalifornia is not a party to the agreement. Ask for labor and parts warranty terms in the quote, and keep the license number with the paperwork.
How does the callback request work?
The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.
Which areas does PlumberCalifornia cover?
All of California: the site lists every covered city with real ZIP codes, the county permit authority and nearby coverage, so requests route to a professional already working that area.
Is PlumberCalifornia a plumbing company?
No. Independent licensed professionals perform and contract the work directly with you. PlumberCalifornia routes the request and links every page to the official California license register.
Does PlumberCalifornia charge homeowners anything?
No. PlumberCalifornia may be compensated by a partner when a homeowner connects with a professional through the site. That never changes what the contractor charges for the job.
