Garbage Disposal Installation Overview

Adding a garbage disposal where one didn't exist before means more than just bolting a unit under the sink. It involves connecting the discharge pipe to your existing drain line, aligning the P-trap correctly so it doesn't leak, wiring the unit to a switched outlet or wall switch, and — if your dishwasher drains through the disposal — knocking out the correct dishwasher inlet plug and connecting that line too.

We size the unit to your household before installing anything: a 1/2 horsepower unit is enough for light use, while larger households or heavier daily use are better served by a 3/4 to 1 horsepower motor. Every installation is tested under running water, with the dishwasher cycle run through if applicable, before we consider the job finished.

What's Included With Garbage Disposal Installation

  • Mounting assembly installation under the sink
  • Discharge pipe and P-trap connection
  • Dishwasher inlet hookup, if applicable
  • Electrical connection to a switched outlet or wall switch
  • Full test run, including a dishwasher cycle if connected

How We Handle Garbage Disposal Installation

  1. Call or book online

    Tell us what's happening — humming, leaking, or dead — and we'll give you a same-day or next-day appointment window.

  2. On-site diagnosis

    A technician identifies the actual cause (jam, seal failure, motor fault, wiring issue) before recommending repair vs. replacement.

  3. Upfront pricing

    You get a clear price before any work begins — repair or new unit installation, no surprise add-ons after the fact.

  4. Repair or install

    Most repairs and standard installations are completed in a single visit, using a properly sized unit when replacement is the better option.

  5. Test and clean up

    Every unit is run under water and tested for leaks, noise, and full drainage before we consider the job finished.

Garbage Disposal Installation Cost

Most disposal repairs cost less than a full replacement — we'll always tell you honestly which one makes more sense for your unit's age and condition.

Frequently Asked Questions — Garbage Disposal Installation

Do I need an electrician for garbage disposal installation?

Usually not, if there's already a switched outlet or wall switch near the sink — our technicians handle the standard electrical connection. If new wiring needs to be run to the location, we'll tell you upfront before starting.

Can you install a garbage disposal where there wasn't one before?

Yes — this is one of our most common installation calls. We'll assess your existing under-sink plumbing and electrical setup and let you know if anything beyond a standard installation is needed.

How long does a new garbage disposal installation take?

A standard installation typically takes 45–90 minutes, assuming no unusual plumbing or electrical modifications are needed.
