Repairing or installing garbage disposal is a bit more complicated than many other plumbing jobs, and it's not the kind of thing you want to do yourself unless you have significant plumbing experience.
Garbage Disposal Repair Costs
There are a number of things that can go wrong with a garbage disposal, from a jam caused by getting something stuck in the blades, to a clog or a leak to the motor going out. If you have to call a repair specialist out, you will be charged a service call, which is usually one hour of labor, plus parts and any additional labor beyond the first hour. These charges can range anywhere from about $50 to more than $200 and depend on how complicated the repair job actually is.
Garbage Disposal Installation Costs
If you have to replace your garbage disposal for whatever reason, the cost will be higher. The units usually run from $150 on up to several hundred dollars depending on factors such as the size of the motor and how much noise it makes. It will take an experienced plumber about two to three hours to install a new garbage disposal unit. You might be charged a fee for disposal of the old unit as well, meaning your total cost could be anywhere from less than $300 to more than $400 on average.
