Garbage disposal replacement cost: unit, labor and when to repair

What the disposal itself costs

Motor size is the biggest price driver. These are Angi’s 2026 ranges for the unit (Angi):

• 1/3 to 1/2 horsepower: $50 to $225. Usually enough for 1 or 2 people.
• 5/8 to 3/4 horsepower: $120 to $310.
• 1 to 1-1/4 horsepower: $200 to $400. Better for households of 5 to 8 people.

Feed type and material matter too. Continuous-feed models run $75 to $1,000, and batch-feed models, which only run with the cover in place, run $75 to $300. Aluminum units cost $75 to $300 but are prone to leaks and corrosion and usually last under 10 years. Stainless steel units cost $400 to $1,100 (Angi).

Labor and extra costs

• Installation. About $50 to $100 an hour, and most jobs take about an hour. Many pros include haul-away of the old unit (Angi).
• Electrical work. Some units plug into an existing outlet. Others need a dedicated 15-amp circuit with GFCI and AFCI protection, which means hiring a licensed electrician (Angi). See our electrical repair guide.

Repair or replace?

Angi says disposals last about 5 to 10 years, and some stainless steel models last up to 15. If yours is newer and simply jammed or won’t turn on, a repair is usually cheaper. A unit that won’t run at all, leaks from the body, grinds metal on metal or needs the reset button often is a candidate for replacement (Angi).

Check the warranty first. Manufacturer warranties run 1 to 10 years, but they usually cover defects only, not damage from what goes down the drain (Angi). If the sink still drains slowly after a new unit, the problem may be the pipe. See our drain cleaning cost guide.

Make the next one last

• On a septic system? EPA says to limit disposal use, because using one can mean more frequent pumping. Have the system inspected every 1 to 3 years and the tank pumped every 3 to 5 years (EPA). See our sewer line repair guide.

Would a home warranty help with the next disposal bill?

A home warranty is a service contract that helps pay to repair or replace some home systems and appliances. Know these numbers before you buy:

• Price. The DC Attorney General says a basic home warranty costs $500 a year or more (DC Attorney General). NerdWallet’s average was about $876 a year (NerdWallet).
• Service fee. You usually pay a fee for each repair visit, typically $75 or more (DC Attorney General). NerdWallet found an average of about $108 (NerdWallet).
• Is the item covered? Some plans exclude kitchen appliances, water heaters, furnaces and other major appliances, or charge extra to cover them (DC Attorney General).
• Caps and exclusions. Claims can be capped. Contracts can exclude wear and tear, manufacturer defects and problems from skipped maintenance. The company may repair rather than replace, and may pick the contractor (DC Attorney General).

A disposal replacement often costs less than a year of a home warranty plan (DC Attorney General), so a plan only makes sense if it covers other aging systems too. Don’t count on a brand-new plan to pay for something that’s already broken; read when coverage starts and what it excludes. See our home warranty cost guide.
