How Much Does It Cost to Replace a Garbage Disposal in 2025?


How Much Does It Cost to Replace a Garbage Disposal in 2025?

Replacing garbage disposal typically costs around $590, at SD Appliance Repair though prices can range from $240 to $665 based on factors like the unit’s type and size.

Garbage Disposal Cost by Motor Size

The motor size of garbage disposal determines how much food waste it can process at once. Larger, more powerful motors come with a higher price tag, so it’s essential to select the appropriate motor size for your household to avoid spending more than necessary. For smaller households with one or two people, a ⅓- or ½-horsepower motor, ranging from $90 to $265, should suffice. Larger households of five to eight people will need a 1-horsepower motor, typically priced between $240 and $440.

Labor Cost to Replace a Garbage Disposal

Replacing an old garbage disposal is generally a simple job that should take about an hour for an SD Appliance Repair technician to complete. Installation typically costs $90 to $140 per hour. The process involves leveling the unit, making a few basic connections, securing the exterior, and testing it. Most professionals will include the removal of the old disposal in their quote, as they’re already dismantling it to install the new one. They’re also familiar with local disposal centers for faulty units. However, if there are issues like a rusted or hard-to-remove disposal, additional charges of $90 to $140 may apply to cover the extra time needed for removal.

Additional Garbage Disposal Replacement Cost Factors

The cost of replacing garbage disposal typically ranges from $240 to $665, with an average of around $590. If you’re experienced with DIY projects, you might spend as little as $115 for a new unit and the necessary tools for installation. Prices vary depending on the unit’s type, motor size, and labor fees.

Feed Type

In the realm of garbage disposals, there are two main types to consider: continuous feed and batch feed. Continuous feed models typically range from $115 to $1,040, while batch feed models are priced between $115 and $340. Continuous feed units are usually more expensive because they allow for ongoing operation without having to pause or cover the unit. On the other hand, batch feed disposals are better suited for homes with children, as the cover prevents accidental activation.

Material

Garbage disposals are typically made from either aluminum or stainless steel. Aluminum units are more affordable and commonly used, ranging from $115 to $340 depending on size and power. However, aluminum disposals are more susceptible to leaks and rust, with a lifespan typically under 10 years. Stainless steel disposals, priced between $440 and $1,140, are more durable and resistant to corrosion and leaks. These models are often preferred in busy households and commercial settings due to their strength and longevity.

Warranties

When you purchase a new garbage disposal, it typically includes a manufacturer’s warranty, and sometimes an additional one from the installer. Be sure to review the details when buying or hiring a plumber to understand what is covered. Warranties can last anywhere from one to ten years, depending on the brand and model. These are limited warranties that cover defects in materials or workmanship, but you’ll still need to use the disposal carefully to avoid costly issues.

Electrical Upgrades

The electrical requirements for your garbage disposal vary based on its model and local building regulations. Some units can be easily plugged into a standard 120-volt outlet and use five to ten amps, while other codes may call for a dedicated 15-amp circuit with GFCI (ground fault circuit interrupter) and AFCI (arc fault circuit interrupter) protection. These safety features ensure the breaker will trip if necessary to prevent hazards. If you’re unsure about the electrical needs for your disposal or need new wiring, it’s best to consult a licensed electrician.

My dryer was giving me problems so I decided to give SD Appliance Repair a try. They were friendly.  They were willing to work around my schedule.  They came within 24hrs.  They fixed my dryer within an hour. I will definitely call them again if I need another repair!.

VERY responsive!  I called the guys on Thursday afternoon for a dishwasher issue and they came by the next day to diagnose the problem.  Turns out I needed a new motor, which the guys ordered, picked up on a Saturday morning, and installed right away.
