Cost to Replace a Garbage Disposal
Replacing a garbage disposal means disconnecting its electrical wiring, dishwasher hose and drain pipes, removing the old mounting assembly, then fitting a new unit with a plumber's-putty sink flange and fresh seals. It is a moderate job often taken on when a disposal leaks, is jammed beyond repair, or has reached its typical 10–12-year lifespan.

DIY or call a pro?
This is a DIY-friendly moderate job, but a professional is worth considering if disconnecting and reconnecting electrical wiring, drain pipes, or the mounting assembly feels unfamiliar. Keep power off at the circuit breaker and confirm it is off with a circuit tester before touching electrical connections. Support the disposal's weight while disconnecting it to avoid injury or damage.
Frequently asked questions
- Can I replace a garbage disposal myself or hire someone?
- A homeowner can take this on when comfortable working with the disposal's electrical connections, drain pipes, dishwasher hose, and mounting ring. Consider hiring help if any of those steps are unfamiliar or if you are unsure about the new unit's sink-flange compatibility.
- What makes garbage disposal replacement pricing go up?
- The price can vary with how many disposal units are being replaced, labor time, the disposal and other materials, haul-away of the old unit, and a minimum or trip charge for a small job.
- What should I check before buying a replacement garbage disposal?
- First verify that the old unit is leaking or jammed beyond repair. Then check whether the new disposal is compatible with the existing sink flange; if the fit differs, plan to replace the flange and use plumber's putty for the new one.
- Why does the old garbage disposal need support during removal?
- The disposal can cause injury or damage if its weight goes unsupported while the mounting ring is loosened and the connections are disconnected. Have the unit supported before releasing it from the mounting assembly.
