A jammed or tripped garbage disposal is a cheap fix — often a $70–$150 reset or clog clearing worth doing on any unit. But a disposal that leaks from the body, or a motor that hums and will not turn, usually means replacement: a new disposal installed runs $150–$400, close to what a major repair would cost.
Typical, national repair costs (parts and labor), compiled from published appliance repair pricing guides. "Worth it" assumes an average-age unit — a newer garbage disposal tips toward repair, an older one toward replace. Researched estimates, not a quote — parts availability and your local labor rate move the real number.
| Failure | Typical repair | Verdict |
|---|---|---|
| Jam / reset / clog | $70–$150 | usually repair |
| Body leak / dead motor | $150–$400 | usually replace |
The 50% rule: replace when the repair is over half the price of a new one AND the garbage disposal is past half its ~12-year life. Run the numbers for yours →
A jam, reset, or clog is worth clearing — a $70–$150 fix. But a leak from the disposal body or a dead motor usually means replacing it, since a new unit installed runs $150–$400, about what the repair would cost.
If it leaks from the body or the internal seals, replace it — those leaks are not economically repairable. A leak at a hose or mounting connection can sometimes be fixed for less.
First try the reset button and free the jam with the hex wrench — that fixes most of these for the cost of a service call. If it still hums with a free flywheel, the motor is done and it needs replacing.
A garbage disposal lasts about 12 years on average, per the National Association of Home Builders.
