Garbage Disposal Installation Estimate FAQs

What’s the difference between continuous feed and batch feed disposals?

Continuous feed disposals cost $75 to $1,000 and are easy to operate — you run water, flip a switch, and feed food scraps continuously — while batch feed disposals cost $75 to $300 and are safer since they only run with the cover in place, though not recommended for households generating lots of food waste.

Can I install a garbage disposal myself to save money?

Yes, for skilled DIYers — you could pay as little as $75 for a new unit and the tools to install it, saving $100–$250 in labor. However, the electrical and plumbing work involved makes the job potentially hazardous, so professional installation is recommended for safety and warranty coverage.

How do I know what size (horsepower) disposal I need?

A small household of one or two people only needs a ⅓- or ½-horsepower motor ($50-$225), while a larger household of five to eight people benefits from a 1-horsepower motor ($200-$400) that handles more food debris without jamming.

Does installing a garbage disposal for the first time cost more than replacing one?

Yes — a brand-new installation (retrofit) where no disposal previously existed typically costs more than a replacement with existing connections, since new electrical wiring and under-sink modifications may be needed.

Is it worth repairing or replacing an old garbage disposal?

Replacement is generally recommended when facing old motor failure, repeated leaks, rust, or repairs exceeding 50% of replacement cost — garbage disposals typically last 8-15 years, so an aging unit with mechanical issues is rarely worth extensive repair.

Do I need an electrician as well as a plumber for installation?

Often yes, if new wiring or a dedicated outlet is needed — having an existing GFCI outlet can eliminate a $100–$250 electrician fee, so checking your current electrical setup before scheduling can save meaningfully on the total project cost.

How long does garbage disposal installation typically take?

Professionals average 45-60 minutes per install, while DIY can take up to 2.5 hours for those less experienced with plumbing and electrical connections.

Very expensive. Make sure you establish the price up front. They did some work on gas pipes, which was specialized so the prices weren't so horrible.

They never called my property manager, or myself, to ask if they could do an additional estimate while at my property. I was shocked. Companies cannot go around doing estimates.
