Whether it's worth repairing your garbage disposal depends on its age and the specific problem. Generally, if the unit is eight years old or younger, repair is a good option. For minor issues like a bad seal or a simple jam, a repair can be inexpensive, sometimes under $10. However, if the motor is broken (a repair that can cost $150 or more) or the unit is getting old, it's often more cost-effective to replace the entire disposal.

Replacing a garbage disposal costs anywhere from $150 to $950, but the average cost is somewhere around $550. There are two types of garbage disposal units, and continuous feed disposals tend to cost more than batch feed disposals. Going for an aluminum garbage disposal is also significantly cheaper than choosing a stainless steel garbage disposal. You'll also need to factor in the horsepower of the motor, labor, and the removal and disposal of your old unit.

Once you have your garbage disposal disconnected, you can remove the mounting bracket by unscrewing the bolts that are holding the bracket. You can back them out just enough to pop off the snap ring, which prevents the bottom portion of the bracket from disconnecting from the top when you unscrew the bolts. Use a regular screwdriver to pop off the snap ring, and the rest of the components should fall off by themselves.

Never put glass in the garbage disposal. It can damage your disposal or eject shards of glass out of the disposal and cause injury. If you get broken glass in your garbage disposal, turn it off and cut the power from the breaker, use a tool like pliers or tongs to remove the glass, and use a wet-dry vacuum to remove the remaining glass pieces. If you can’t access the disposal safely, call a garbage disposal repair pro.
