Plumber vs Appliance Installer: Who Should Install Your Dishwasher?
The right choice depends entirely on your job type. Hiring the wrong trade wastes money or gets you a job that cannot legally be done.
| Your Situation | Who to Hire | Approximate Cost | Why |
|---|---|---|---|
| Replacing existing dishwasher (hookups in good shape) | Appliance tech | $150-300 | Cheapest option, no plumbing license needed for existing hookup connection |
| Replacement (want bundled retailer service) | Home Depot/Lowe's | $99-150 | Convenient if buying appliance from them; must be standard swap |
| First-time install (new plumbing lines) | Licensed plumber | $300-700 | Required by law; only plumbers can run new water/drain connections |
| New dedicated electrical circuit needed | Licensed electrician | $250-900 | Separate visit from plumber; permit required in all jurisdictions |

Home Depot uses third-party contracted installers, not their own employees. Quality and availability vary by market. The $99-150 price covers a standard replacement only - new hookups, hardwired units, and complex jobs cost extra (and quotes for those are less consistent). Always confirm what is and is not included before the appointment.
What Home Depot installation does NOT cover:
- ! New hookup installations
- ! Hardwired unit disconnection/reconnection (typically)
- ! Permits for any work
- ! Appliances not purchased from Home Depot

FAQ
Do I need a plumber to install a dishwasher?
For a replacement with existing hookups: no. An appliance technician handles it for $150-300 and is the right choice. For a first-time installation with no existing water supply or drain connections: yes, a licensed plumber is required. The plumber runs new supply and drain lines, then typically installs the dishwasher as part of the same job. Budget $300-700 for a first-time install including the appliance hook-up.
How much does Home Depot charge to install a dishwasher?
Home Depot charges $99-150 for basic dishwasher installation when you purchase the appliance from them. This uses third-party contracted installers. The service covers standard replacements where existing hookups are in good condition. New installations, hardwired units, and complex jobs require a separate quote that can add $100-400 to the base price. Lowe's offers the same service at similar pricing.
What questions should I ask a dishwasher installer before booking?
Key questions: Is haul-away included? Are permits included? Will you inspect existing hookups before the appointment? What is your license number? For new installs: do you handle both plumbing and electrical, or do I need a separate electrician? Always ask for a written quote with specific line items before confirming the booking.
