Garbage Disposal Installation in Columbus, Ohio

Transit & Flow Group installs garbage disposals under kitchen sinks across Columbus and Central Ohio, whether that means replacing a unit that finally seized up or adding a disposal to a sink that has never had one. Every install connects to the sink drain, the dishwasher drain line if applicable, and power, either through an existing outlet or a dedicated switch, and every unit gets tested for leaks and proper grinding before we leave.

Is this the right service for you?

This fixed-price service covers installing a garbage disposal under an existing kitchen sink, whether that is:

• Replacing an old or broken disposal with a new unit in the same location
• Adding a disposal for the first time to a sink that currently drains straight through without one

Both scenarios are handled under this one service because the core plumbing work, connecting to the sink flange, the drain trap, and the dishwasher drain line, is similar either way. What differs is whether we are also disconnecting an old unit first.

It is not the right page if your kitchen sink itself needs replacing or reconfiguring, or if the disposal will require a brand-new dedicated electrical circuit and switch where none currently exists near the sink; that circuit work is scoped as an add-on or a separate electrical project, noted below.

How pricing works

Garbage Disposal Installation is fixed pricing: a published flat rate for installing a disposal under an existing kitchen sink, plus clearly stated add-ons for complications found once the old unit comes out or the plumbing is opened up.

The base fixed price assumes a standard sink flange and drain configuration and an existing, usable power source near the sink, either a switched outlet or a plug-in cord setup. Add-ons apply for:

• Code-required upgrades, such as adding a dedicated switch or GFCI-protected outlet where the sink cabinet has none
• Faulty existing plumbing found on site, such as a corroded drain trap, a leaking dishwasher drain connection, or an outdated flange that will not seat a new unit
• Adding an air gap or high-loop for the dishwasher drain line where local code requires it and one is not already present
• Haul-away of the old disposal unit

As general market context, not a Transit & Flow Group quote, Forbes Home’s data puts garbage disposal installation at roughly $150 to $950, averaging around $400, with straightforward replacements at the lower end and first-time installs or units needing plumbing modifications running higher. Starting at $299.

Under Central Ohio kitchen sinks: what we find and why it matters

Garbage disposal work is one of the more variable jobs in Central Ohio kitchens because so much depends on what is already under the sink. Older homes in neighborhoods like Clintonville, German Village, and Bexley sometimes still have cast iron or older PVC drain assemblies, and sink cabinets that were never wired for a disposal at all, since disposals were less standard when these homes were built. Adding one there often means running a switch or outlet to the cabinet, work we flag and price as an add-on rather than bury in the base rate.

Newer builds in Dublin, New Albany, and Lewis Center almost always come with a disposal-ready outlet and switch already in place, since disposals have been standard builder-grade equipment for years now. Replacement jobs there tend to be quick, especially when the new unit is a similar size and mounting style to the old one. Where things still slow down is horsepower and size: a homeowner upgrading from a basic entry-level unit to a larger continuous-feed model sometimes needs a bigger cabinet cutout or a sturdier mount, which we check before starting.

One Central Ohio wrinkle worth knowing: some older suburbs and a portion of homes on private septic systems have restrictions or strong recommendations against heavy disposal use, since ground food waste can affect septic tank load over time. We will flag this if it applies to your property, and permits and inspections may be required for the plumbing or electrical portion of the work depending on your municipality.

Our process

1. Describe your sink setup online. Photos under the sink, your disposal brand if replacing one, and any known issues go into the Estimate Builder for a preliminary online estimate.
2. On-site check. We inspect the sink flange, drain trap, dishwasher drain connection if present, and the power source before starting.
3. Remove old unit, if present. The old disposal is disconnected and removed.
4. Install and connect. The new disposal is mounted, drain and dishwasher connections are made, and power is connected.
5. Test and walkthrough. We run water and test the grind cycle, check every connection for leaks, and confirm final scope and price against what we found.

Services completed by appropriately qualified professionals where required.
