A garbage disposal looks like a simple swap, and sometimes it is. Other times a missing outlet, a rusted sink flange or a drain that does not line up turns an hour into an afternoon. This guide explains what actually moves the price of a disposal installation in a Savage kitchen, so you can read a quote with confidence.
We do not list exact dollar figures here because they change with the unit, the house and the day. Instead you will see the pieces that add up, in the order they usually appear on a bill.
The unit itself
Disposals are sold by motor power, usually from a quarter horsepower to a full horsepower and a little more. A small motor suits a couple that cooks lightly. A bigger motor handles a family that scrapes plates daily and grinds more fibrous scraps. Higher power costs more, but it also jams less.
Features add cost too. Sound insulation, stainless grinding parts, a continuous feed or batch feed design and longer warranties each push the price up. A mid-range unit is the right choice for most households.
| Tier | Who it suits | What you give up |
|---|---|---|
| Basic, smaller motor | One or two people, light use | Jams more often, shorter warranty |
| Mid-range | Most households | Moderate noise |
| Premium, larger motor | Heavy use, large families | Higher price, more weight under the sink |
Labor and the job around the unit
A direct swap onto an existing mount and outlet is the cheap case. Costs rise when the old mounting ring is seized, when the drain tailpiece does not line up or when the sink flange needs new plumber's putty or a replacement.
- Removing and hauling away the old unit
- Resealing the sink flange so it does not leak at the top
- Connecting the dishwasher drain inlet and clearing its knockout plug
- Replacing a worn trap or tailpiece that no longer fits
- Testing for leaks and running the unit
That dishwasher knockout is a classic surprise. If you skip it, the dishwasher cannot drain through the disposal. Ask the installer to confirm it is open.
Electrical: the cost people forget
A disposal needs power. Some are hardwired, others use a cord and plug into a switched outlet under the sink. If your sink has no outlet, adding one is a separate task, and in many homes it needs an electrician or a plumber who is licensed for the work. A switch on the wall or an air switch on the counter can be added as well.

Do it yourself or hire a plumber?
A handy homeowner with a like-for-like swap can finish in an afternoon. The risk is a slow leak that rots a cabinet floor over months. A plumber is worth the cost when you are changing the sink setup, adding an outlet or dealing with older, corroded drain parts.
Our garbage disposal repair service covers both installs and repairs, and we can install a unit you bought yourself. Many Savage homeowners call us after a first attempt leaves a drip.
Hard water and disposal life
Hard water leaves scale on the grinding chamber and inside the drain. A disposal in a home with very hard water can lose power and develop a stubborn smell sooner. Running cold water while grinding and a few seconds afterward moves scraps through the trap. A water softener reduces the scale.
A realistic installation day
Plan for the sink to be out of service for a few hours. The installer clears the cabinet, disconnects the trap, removes the old unit and cleans the sink opening. Old plumber's putty scrapes away, the flange is reseated with fresh putty and the mounting assembly is locked in place.
The new unit hangs from the mount, the drain elbow reconnects and the dishwasher hose attaches. Then comes the leak test with the cabinet bare, because a drip hides well behind stored cleaning supplies.
What to know in Savage
The City of Savage buys about 71.5 percent of its distributed water from Burnsville, whose 2025 water report states hardness of 25 to 26 grains per gallon. Savage's own report does not list hardness, so test your tap or ask City of Savage Utility Services.
Minnesota requires a plumbing contractor license for plumbing work in communities with more than 5,000 residents, and the state Department of Labor and Industry offers a free license lookup. Check anyone you hire before they start. Ask the City of Savage building department whether your project needs a permit.

Code and sources
Minnesota Rules chapter 4714 is the state plumbing code and the standard a licensed plumber works to. The Department of Labor and Industry states that it incorporates the 2018 Uniform Plumbing Code with Minnesota amendments. Your city building department decides when a permit or inspection is needed, so check with them before work begins.
Questions to ask any installer
- Does the quote include the old unit's removal and disposal?
- Is the dishwasher inlet connected and open?
- Who handles the electrical connection, and is it included?
- What is the warranty on the unit and on the labor?
- Will you test for leaks with the cabinet empty and a flashlight?
For homes near Prior Lake that run a septic system, check with your septic pro before adding a disposal, because extra solids affect tank pumping schedules. Our Prior Lake page covers the area, and the Shakopee page covers neighbors to the west.
Questions Savage homeowners ask
No. A larger motor jams less and costs more. For most households, a mid-range unit is enough.
You need power. Adding an outlet is a separate step and may need a licensed professional.
A like-for-like swap often takes an hour or two. Extra work stretches it.
Scale can reduce performance over time. Running cold water and cleaning regularly slows it.
Yes. The state Department of Labor and Industry has a license lookup tool on its website.
