Factors That Affect the Cost of Garbage Disposal Replacement

The cost of garbage disposal replacement can be influenced by factors such as the materials used, the size of the unit, labor fees, and any additional costs associated with installation.


You need the right tools and parts to change your garbage disposal. The cost of these materials depends on the type of unit you choose. If you pick a high-end model, it can cost up to $625.

But, if you stick with a basic one, it may only set you back about $75. As well as buying the disposal unit itself, you must also purchase any needed pipes or fittings.


The size of the garbage disposal is an important factor that affects the cost of replacement. Smaller units with less horsepower and capacity are generally cheaper to replace compared to larger, more powerful models.

The average cost to replace a small-size garbage disposal unit is around $150 to $300, while larger units can range from $400 to $950. It’s essential to consider your needs and kitchen requirements when choosing the right size of garbage disposal, as it can impact both the initial cost and long-term performance.

Keep in mind that larger units may require additional labor or installation fees due to their weight and complexity.


The cost of labor is an important factor to consider when replacing a garbage disposal. Hiring a professional for installation can add significantly to the overall cost, usually ranging from $100 to $350.

However, skilled DIYers may be able to save money by doing the replacement themselves. Keep in mind that if you choose to do it yourself, there are risks involved, such as damaging pipes or electrical components.

It’s important to weigh the potential savings against the risk and your own skill level before deciding whether to hire a professional or take on the job yourself.

Additional Costs

In addition to the cost of materials, labor, and installation fees, there are some additional costs to consider when replacing a garbage disposal. These can include necessary permits or inspections, which may add extra charges to the overall cost.

Additionally, if your plumbing system needs any repairs or modifications in order to accommodate the new garbage disposal, you may need to budget for those expenses as well. It’s important to factor in these potential additional costs when planning your budget for garbage disposal replacement.

Maximizing Lifespan

To maximize the lifespan of your garbage disposal and avoid costly replacements, there are a few simple tips you can follow. First, always run cold water while using your disposal to help flush away debris and prevent clogs.

Dos and Don’ts for Proper Use

To make sure you use your garbage disposal properly and avoid potential issues, here are some important dos and don’ts to keep in mind:

  2. DON’T put non – food items down the disposal. It’s essential to only dispose of food scraps in the unit to prevent damage or blockages.
  3. DO cut large food items into smaller pieces before putting them down the disposal. This ensures smoother grinding and reduces the risk of clogs.
  4. DON’T overload the unit with too much food at once. Feed smaller amounts of waste gradually to avoid overworking the motor and jamming the system.
  5. DO clean your garbage disposal regularly. Use a mixture of baking soda and vinegar or dish soap to remove odors and buildup.
  6. DON’T pour harsh chemicals or drain cleaners down the disposal as they can damage the unit’s components.
  7. DO use citrus peels or ice cubes occasionally to freshen up your disposal and help sharpen its blades.
  8. DON’T stick your hand or any objects into the garbage disposal while it’s running, even if it appears to be blocked. Always turn off the power before attempting any repairs or removals.
