Kitchen Garbage Disposal Installation in Columbus, Ohio

Transit & Flow Group installs new garbage disposals and replaces failed units for kitchens across Columbus and Central Ohio, whether you’re adding a disposal to a sink that never had one or swapping out a unit that’s jammed, leaking, or dead. Enter your kitchen’s details and photos in the Estimate Builder for a preliminary online estimate.

Is this the right service for you?

Kitchen Garbage Disposal Installation fits a few common situations we see across Central Ohio kitchens:

• Your disposal hums but won’t turn, is jammed, or leaks from the bottom, and it needs to be replaced rather than repaired
• You’re adding a disposal to a sink that has never had one, which means new drain plumbing under the sink
• You’re upgrading to a more powerful or quieter unit as part of a kitchen refresh
• Your disposal is old enough that parts are hard to find and replacement makes more sense than repair

This work commonly overlaps with two other services on our site. If you’re also replacing your kitchen faucet, especially if the faucet swap involves diagnostic work on old supply lines or valves, our Kitchen Faucet Replacement service covers that side of the job, and the two are frequently bundled into one visit since both involve working under the same sink. If you’re also installing a new dishwasher, our Kitchen Dishwasher Installation service covers that separately, since dishwasher drain lines sometimes route through the disposal itself. Booking disposal work alongside either of those means one visit under the sink instead of two.

How pricing works

Garbage disposal installation is priced based on what’s involved:

• New installation versus replacement. Adding a disposal where none existed requires new drain plumbing and sometimes a new electrical connection, which takes more time than swapping an existing unit.
• Unit horsepower and features, since larger, quieter, or higher-horsepower units mount the same way but may need different electrical support.
• Existing plumbing and wiring condition, including whether the drain configuration under your sink is compatible with the new unit and whether existing wiring is adequate.
• Bundling with faucet or dishwasher work, which can share some setup time if scheduled together.

As general market context, not a Transit & Flow quote, Angi’s 2025 data lists garbage disposal installation costing roughly $150 to $400 on average, with new installations (versus straightforward swaps) tending toward the higher end when new plumbing or wiring is required.

What’s included

• Removal of your old disposal unit, when replacing an existing one
• New drain plumbing configuration, when installing a disposal where none previously existed
• Mounting and connecting the new disposal unit
• Electrical connection to existing wiring, or a note if new wiring is required
• Leak and function testing before we leave
• A final walkthrough confirming proper operation

What’s not included

• Kitchen faucet installation or replacement itself, quoted under our Kitchen Faucet Replacement service (though frequently bundled with disposal work)
• Dishwasher installation itself, quoted under our Kitchen Dishwasher Installation service
• New electrical circuits or panel work, quoted separately if your kitchen needs one to support the new unit
• Repair of existing disposal units; this service is for installation and replacement, not troubleshooting a jam or clog on a unit you intend to keep
• Countertop or sink modifications to accommodate a differently sized unit

Central Ohio kitchen plumbing

Many Columbus-area homes, especially older ones in neighborhoods like Clintonville, Grandview, and Whitehall, were built before garbage disposals were standard kitchen equipment, so adding one means running new drain plumbing under a sink that was never configured for it. Central Ohio’s older housing stock also means the drain trap and wiring under a sink can be decades old, so we check both before mounting a new unit rather than assuming a modern connection is already in place.

In newer construction across Dublin, Westerville, and New Albany, most kitchens already have disposal-ready plumbing and wiring, making a straightforward swap when a unit fails the more common call. Either way, disposal work is one of the more frequent add-ons to a broader kitchen project, since it’s often noticed only once a faucet or dishwasher project already has the cabinet open and the plumbing exposed.

Our process

1. Tell us what’s happening. New installation or replacement, unit preferences if any, and photos of under-sink plumbing, submitted through the Estimate Builder for a preliminary online estimate.
2. We assess your plumbing and wiring to confirm what the new unit needs and whether anything requires upgrading first.
3. Written scope and pricing, itemized separately if bundled with faucet or dishwasher work. Final scope and price subject to verification on site.
4. Installation, including new drain plumbing if none previously existed.
5. Leak and function testing, with a final walkthrough before we consider the job complete.
