What the price includes
The price usually covers the new disposal, a plumber or handyman's labor, and the hookup to the drain and power. Removing the old unit may cost $25 to $50 extra. A new outlet, pipe changes, a dishwasher hose, permits and leak repairs cost extra. Ask for a written quote. It does not include tax or extras the provider adds on the day.
DIY or hire a pro
A simple swap can be a DIY job if you can turn a wrench and the hookups are the same. Doing it yourself saves labor, which HomeGuide lists at $100 to $250. You still pay for the unit and tools. A first time install needs a plug, a drain hookup and sometimes a new pipe, which is harder. Water and power near each other can be risky. A leak can ruin a cabinet. If there is no outlet under the sink, or you are not sure, hire a pro.
How to tell you need it
You may need a new disposal if it hums but does not spin, leaks, smells bad even after cleaning, jams all the time or trips its reset button. Old units can also be loud and slow. If it is stuck, you can first try a hex key in the bottom to free it. If it keeps failing or leaks from the body, replacement costs less than repeat repairs.
How to judge your quote
- Ask if the quote includes the unit, labor, removal of the old one and parts.
- Ask if you need a new outlet, since it can add $150 to $350.
- Ask what motor size the price covers.
- Ask if there is a service fee, and if it is waived when you hire the shop.
- Compare the total with the range above: $150 to $950 per job for most people in 2026.
Ways to pay less
- Pick a motor size that fits your home. A 1/2 HP unit costs $100 to $150 at HomeGuide and fits most small families.
- Swap an old unit for a new one with the same hookups. HomeGuide lists swaps at $200 to $550, lower than a new install.
- Get at least three quotes. Fixr lists $300 to $600 while Liberty Home Guard lists $200 to $625, so shop around.
- Buy the unit yourself at a store and ask the plumber to install it. Compare this with a package price first.
- Ask for one visit for all work. Fix a leak or a drain issue at the same time so you pay only one service fee.
Why this costs more in 2026
Trade labor now runs about $75 to $150 an hour in most of the US. Lumber, steel, copper, PVC and concrete all cost more than in 2024, and freight went up after the oil shock that began with the Iran war in February 2026. Installs cost more in 2026 because plumber labor rates have risen and the units and parts cost more to ship.
