What drives the price up or down
- Unit horsepower: A 1/3 hp entry-level model handles light use but struggles with fibrous foods. A 3/4 hp or 1 hp unit costs more upfront but runs quieter and grinds more waste per cycle.
- New vs. replacement: Swapping an existing unit into the same mounting assembly takes 30 to 60 minutes. A first-time install with no prior wiring or drain connection takes two to three hours and costs more in labor.
- Electrical requirements: Most disposals plug into an existing outlet under the sink. If your kitchen lacks a dedicated circuit, an electrician must add one, which adds $100 to $300.
- Local labor rates: Plumbers in major metros charge $80 to $150 per hour. Rural areas run $50 to $80 per hour.
- Permit requirements: Some jurisdictions require a permit for new electrical circuits or drain modifications. Check with your local building department before starting work.

How much does Home Depot charge to install a garbage disposal?
Home Depot's installation service runs $119 to $200 for a standard disposal swap when you purchase the unit from them. The work is performed by independent local contractors in their network. Scheduling can take several days depending on your area. Calling a local licensed plumber directly often gets the job done faster at a comparable or lower total cost, particularly if you already own the unit you want installed.
How much should someone charge to install a garbage disposal?
A fair market rate for a professional garbage disposal installation is $100 to $200 for labor on a straightforward swap, or $150 to $350 for a first-time install that involves new wiring or drain connections. If a quote is significantly above that range, ask for an itemized breakdown. If it is well below $100 for labor, confirm the contractor is licensed and insured. Always get at least two quotes before committing.
Does a plumber or electrician install a garbage disposal?
A licensed plumber handles most garbage disposal installations. The job primarily involves connecting the unit to the drain, securing the mounting assembly, and plugging the power cord into the existing outlet under the sink. An electrician is only needed when there is no existing outlet and a new dedicated circuit must be added. In that case, hire an electrician for the circuit work and a plumber for the actual disposal installation, or find a contractor licensed in both trades.
How many hours does it take to install a garbage disposal?
A standard replacement on an existing mount with working wiring takes 30 to 60 minutes. A first-time installation where no prior wiring or drain connection exists typically takes two to three hours. If the drain lines need repair or the cabinet configuration is tight, add another 30 to 60 minutes. Most plumbers schedule disposal installs as a half-morning job unless other plumbing work is being done at the same time.
DIY vs. professional installation
Replacing a disposal on an existing mount is one of the more approachable DIY plumbing jobs. InSinkErator and Badger units use a twist-lock mounting ring that makes swapping straightforward. If you are comfortable under a sink and the wiring is already in place, you can save $100 to $200 in labor. Any work involving new drain connections or electrical circuits is best left to licensed professionals to avoid leaks, code violations, or voided warranties.
Get quotes from a licensed plumber before deciding. Many plumbers bundle the unit and labor at a price close to what you would pay buying the unit yourself plus a separate service call. Some also carry popular units on their trucks, which means no hardware store trip and a single warranty covering both parts and labor.

Bottom line
Budget $250 to $400 for a mid-range garbage disposal installed by a professional in 2026. First-time installs with new wiring run higher, closer to $400 to $600. Get at least two quotes from licensed plumbers in your area, ask for itemized pricing on parts and labor, and confirm whether the quote includes disposal of your old unit.
