Garbage Disposal Repair

Garbage Disposal Repair in Denver and Boulder County

A disposal that hums, leaks or backs up your sink can throw off the whole kitchen. We repair common disposal models, both continuous-feed and batch-feed units, in 21 cities across the Denver Metro Area and Boulder County. That includes disposals tied into a dishwasher drain, where one problem often shows up as another.

PointLine is a small, family-owned company started by an experienced appliance technician and his wife after years at other repair companies. We saw how often homeowners were left guessing about pricing and timing, so we built our business around the opposite. You get a firm price before any work starts, honest advice about whether a repair makes sense, and a 90-day parts and labor warranty on completed repairs.

Troubleshooting

Common Garbage Disposal Problems We Fix

Most disposal trouble comes down to a handful of symptoms. Here is what usually causes each one, what your technician checks first, and one safe thing you can look at before you call.

Garbage disposal hums but won't spin

Likely cause:: A humming disposal is getting power, but the grinding plate is stuck. Usually a fruit pit, bone fragment or small object has jammed the flywheel, though a seized motor bearing can do the same thing.
What we check:: Your technician frees the plate manually and checks whether the motor turns smoothly or drags under load.
Typical fix:: Most often the jam is cleared and the unit tested; if the bearings or motor have failed, we discuss repair versus replacement with a firm price.

Try first: With the switch off and the unit unplugged or the breaker off, try turning the hex socket on the bottom of the disposal with the wrench that came with it, and never put your hand inside.

Garbage disposal won't turn on

Likely cause:: Silence usually means no power is reaching the motor. A tripped reset button, a tripped breaker or GFCI outlet, a failed wall switch or a burned-out motor are the usual suspects.
What we check:: Your technician confirms power at the outlet and switch, then tests the motor and internal thermal protector.
Typical fix:: Typical repairs include replacing a faulty switch or power cord, or replacing the unit if the motor itself has failed.

Try first: Press the red reset button on the bottom of the disposal, then check your breaker panel and any GFCI outlet under the sink.

Garbage disposal leaking from the bottom

Likely cause:: A leak from the bottom of the housing usually means the internal seals have worn out or the housing has cracked. Water then escapes past the motor, which is not something seals can be patched around.
What we check:: Your technician dries the unit and runs water to pinpoint whether the leak is from the body, the drain connection or a hose above it.
Typical fix:: Leaks at the connections are resealed or replaced, while a leak through the housing typically means a new disposal is the sensible fix.

Try first: Put a dry towel or shallow pan under the unit and run water briefly to see exactly where the drip starts.

Garbage disposal leaking at the sink flange

Likely cause:: The flange is where the disposal meets the sink drain opening. Over time the plumber's putty or gasket dries out, or the mounting assembly loosens from vibration.
What we check:: Your technician fills the sink and watches the flange and mounting ring to confirm the leak point.
Typical fix:: We remove the unit, reseal the flange and tighten the mount so the disposal sits secure and watertight.

Try first: Fill the sink partway with the stopper in and check under the sink with a flashlight; if it only drips when the sink is full, the flange is the likely cause.

Garbage disposal sink draining slowly or clogged

Likely cause:: Starchy or fibrous food, grease and coffee grounds can pack into the disposal outlet or the drain trap below it. Running the unit without enough water makes buildup more likely.
What we check:: Your technician checks the disposal discharge, the trap and the dishwasher connection to find where the blockage sits.
Typical fix:: We clear the blockage and clean the connections, and we will tell you plainly if the problem is in the drain line rather than the disposal.

Try first: Run cold water with the disposal on for a short time, and skip chemical drain cleaners, which can damage the unit and make repair work hazardous.

Garbage disposal grinding or rattling noise

Likely cause:: Metal-on-metal sounds usually mean something hard, like a utensil, bottle cap or bone, is loose in the chamber. A loose mount or worn bearings can also cause rattling or a rough grinding sound.
What we check:: Your technician inspects the chamber, the grinding components and the mounting assembly for loose or worn parts.
Typical fix:: We remove foreign objects, secure the mount, and replace the unit if the bearings or grinding parts are worn beyond repair.

Try first: With the power off, shine a flashlight into the drain opening and remove anything you see using tongs or pliers, never your fingers.

Garbage disposal bad smell

Likely cause:: Food residue trapped under the splash guard, on the grinding plate or in the drain line slowly breaks down and smells. A partially clogged trap or a dishwasher drain connection holding dirty water can add to it.
What we check:: Your technician looks for buildup in the chamber and splash guard and checks that water drains fully from the unit and dishwasher hose.
Typical fix:: We clean the affected parts, clear any standing water in the drain path and correct a poorly routed dishwasher hose if needed.

Try first: Lift and scrub the rubber splash guard with dish soap and a brush, then run cold water with the disposal for a short time.

Garbage disposal keeps tripping the reset button

Likely cause:: The reset button is a thermal overload that shuts the motor off when it works too hard or gets too hot. Repeated tripping points to frequent overloading, a partial jam or a motor that is starting to fail.
What we check:: Your technician checks for a partial jam, then tests how the motor runs under a normal load.
Typical fix:: Clearing the restriction often solves it, but a motor that overheats under light use usually means replacing the disposal.

Try first: Feed food in smaller amounts with a steady stream of cold water and let the unit run a few seconds after the grinding stops.

Disposal Types

Continuous-Feed vs Batch-Feed Disposal Repair

Both kinds of disposals grind food the same basic way, but they turn on differently and tend to fail in slightly different ways. We repair both.

Continuous-feed

Continuous-feed disposals

Run from a wall switch and stay on while you feed food in, which makes them the most common type in Denver area kitchens.
Easy to overload because food can be added nonstop, so jams and tripped reset buttons are frequent calls.
The wall switch and its wiring are part of the system, so a dead disposal is sometimes a switch problem.
Running plenty of cold water during and after use goes a long way toward preventing clogs.

Batch-feed

Batch-feed disposals

Only run when the stopper or cover is placed in the drain opening, so there is no wall switch.
Food is ground one load at a time, which naturally limits overloading.
When one won't start, the stopper's activation mechanism is often the first thing your technician checks.
Some homeowners prefer them because nothing can fall in while the unit is running.

Many disposals also receive the dishwasher's drain water, so a clog or failing disposal can cause the dishwasher to drain poorly or back up into the sink. We check that connection on every disposal call.

Colorado Know-How

Garbage Disposal Care for Colorado Homes

Sources: Denver Water — water hardness, City of Golden, City of Thornton.

Most of the water in the Denver Metro Area comes from mountain snowmelt, through Denver Water, Northern Water and the Colorado-Big Thompson system, Clear Creek and other sources. Denver Water describes its water as soft to moderately hard, with the southern system moderately hard and the northern system somewhat soft, and notes it tends to form scale. Golden also describes its water as soft to moderately hard, and some residents there add softening. Thornton reported higher mineral content and hardness than normal in autumn 2026.

Scale and food residue tend to build on each other. A light mineral film inside the chamber and drain gives grease and food particles something to cling to, which can lead to odor and slow drainage over time. Running cold water during and after each use, cleaning the splash guard regularly and grinding a handful of ice now and then helps keep surfaces cleaner.

What goes down the drain matters most. Grease, coffee grounds, eggshells, pasta, rice, potato peels and fibrous foods like celery are behind many of the clogs we see, and they can also back up into a connected dishwasher. If your dishwasher drains through the disposal, keeping the disposal clear and the drain hose properly routed protects both appliances.

Maintenance Checklist

How to Make Your Garbage Disposal Last Longer

A few small habits prevent most of the jams, clogs and odors we see. None of them take long, and all are safe to do yourself.

A yearly maintenance visit is included in the PointLine Care Club, along with free service calls all year. It's a simple way to keep your disposal and other appliances in good shape.

Join the Care Club — $99/yr What's included

Every load
Run a steady stream of cold water before, during and for a few seconds after grinding. Cold water keeps grease solid so it moves through instead of coating the drain.
Every load
Feed food in small amounts and keep grease, coffee grounds, eggshells, pasta, rice and fibrous scraps out of the drain. Toss them in the trash or compost instead.
Every week
Lift the rubber splash guard and scrub both sides with dish soap and a brush. This is where much of the odor-causing residue hides.
Every month
With the water running, grind a handful of ice cubes to help knock residue off the grinding parts. Follow with a few citrus peels for a fresher smell.
Every few months
Look under the sink with a flashlight for drips at the flange, drain connections and dishwasher hose. Catching a small leak early protects your cabinet.
Once a year
Have the disposal and its dishwasher drain connection checked, especially if your home's water tends to leave scale. A technician can spot worn seals or a loose mount before they fail.

Honest Advice

Repair or Replace Your Garbage Disposal?

How long a disposal lasts depends on how it's used and what goes down it, so age alone doesn't decide it. These simple rules help.

1
Age vs cost: if the unit is older and the repair is significant, put that money toward a new disposal; if it's newer, repair usually wins.
2
The 50% rule: if a repair would cost more than half the price of a comparable new disposal, replacing it is usually the better value.
3
Replacing makes more sense when the housing is cracked and leaking from the bottom, or when the motor has burned out or keeps overheating.

Still have a question?

Give us a call — we'll be glad to help.

(720) 285-3573

How much does garbage disposal repair cost?

It starts with a $85 diagnostic visit, which is credited toward the repair if you go ahead. After diagnosing the problem, your technician gives you a firm price before any work begins, so there are no surprises.

Do you offer a warranty on disposal repairs?

Yes, every completed repair comes with a 90-day parts and labor warranty. If the same issue comes back within that time, we return to make it right.

Can you come out the same day?

Often, yes, but we can't guarantee it. Call (720) 285-3573 or book online early in the day for the best chance at a same-day visit.

Is a continuous-feed or batch-feed disposal better?

Neither is better for everyone; it depends on how you cook and what you're comfortable with. Continuous-feed units are more common and convenient, while batch-feed units only run with the cover in place, which limits overloading and keeps hands out of the chamber.

Is it worth repairing an older garbage disposal?

It can be, if the problem is a jam, a switch or a connection leak. If the motor has failed or the housing is leaking, a new unit is usually the better value, and we'll tell you honestly which applies.

What should I do if my sink is full of water and the disposal won't drain?

Turn off the disposal and stop running water or the dishwasher. Skip chemical drain cleaners, press the reset button once, and if the sink still won't drain, call us so we can clear the clog safely.

Which disposal brands do you repair?

We repair common disposal models, both continuous-feed and batch-feed. If you're unsure about your unit, share the model number when you book and we'll let you know.

Is your garbage disposal humming, leaking or jammed?
