Replacing a garbage disposal costs $200 to $550 with existing connections, while installing one where none existed runs $250 to $650, according to HomeGuide.[2] Angi puts 2026 replacement costs at $200 to $625 with a $550 national average, and Forbes Home reports a $400 average installation over a $150 to $950 range on a page last verified in February 2024.[1][3] The unit itself is usually $100 to $300, so labor and site conditions decide the rest.[2]
Safety first: power off at the breaker before any disposal work. InSinkErator’s own installation guidance starts with two conditions: read and understand the entire safety and installation manual for your exact model, and turn off electrical power at the fuse box or circuit breaker before disconnecting anything. If you are unsure about your home’s wiring, bring in a licensed electrician.[4][1]

Labor cost to install a garbage disposal
| Who does the work | Labor cost as published |
|---|---|
| Plumber (HomeGuide) | $100 – $250 per replacement job (about 2 hours in ideal conditions) |
| Handyman (HomeGuide) | $80 – $160 per replacement job (about 2 hours in ideal conditions) |
| Home Depot or Lowe’s installation service (per HomeGuide) | $120 – $200 per replacement job, unit not included; favorable site conditions |
| Pro hourly rate (Angi) | $50 – $100 per hour; most jobs take about an hour |
| Pro hourly rate (Forbes Home) | $50 – $100 per hour |
Labor cost to install or replace a garbage disposal. Sources: HomeGuide, Angi and Forbes Home. Angi notes a corroded or hard-to-access old unit can add up to $100 in extra labor, and HomeGuide lists hourly rates of $45 to $150 for plumbers, $40 to $100 for electricians and $50 to $80 for handymen.
Feed type and material: the publishers disagree
On continuous-feed versus batch-feed pricing, the sources do not line up. Angi lists continuous-feed units at $75 to $1,000 and batch-feed at $75 to $300, describing continuous models as the higher-priced option.[1] HomeGuide lists continuous-feed at $75 to $300 and batch-feed at $200 to $350, describing continuous models as the cheapest and most common.[2] Both sets of figures are reported as published. On material, Angi puts aluminum units at $75 to $300 and stainless steel at $400 to $1,100, while Forbes Home reports $70 to $350 for aluminum and $400 to $1,200 for stainless.[1][3] Angi also notes batch-feed models only run with the drain cover on, which is why they suit households with children.[1]
Extra costs to budget for
| Extra | Cost (HomeGuide) |
|---|---|
| Install an electrical outlet | $150 – $350 per outlet |
| Replace sink drain pipes | $100 – $350 per job |
| Electrical permit | $50 – $350 per permit |
| Plumbing permit | $30 – $500 per permit |
| Remove old unit only | $25 – $50 per job during a replacement; $125 – $350 for a permanent removal |
| Kitchen sink + faucet + disposal together | $780 – $2,550 per project, existing pipes only |

Repair or replace?
HomeGuide prices a garbage disposal repair at $100 to $250 against a $200 to $550 replacement, which makes minor fixes worth attempting and major ones worth pricing both ways.[2] Angi’s list of replacement signs: no operation when powered, leaks from the unit body rather than the pipes, slow or weakened performance, slow draining with clear pipes, frequent reset-button use, and metal-on-metal or persistent grinding noises.[1]
DIY or hire a pro?
InSinkErator publishes homeowner replacement instructions for its own disposals, with the conditions quoted in the safety note above: read the full manual for the exact model, kill power at the fuse box or breaker first, and test every connection for leaks before calling the job done.[4] Both cost publishers still lean toward professional installation: Angi warns that DIY mistakes risk leaks and code problems, and Forbes Home notes that continuous-feed models need wiring work that often means hiring an electrician.[1][3] If your swap fits the manufacturer’s conditions, compare models in The Home Depot’s Garbage Disposals category.
