Short answer
A garbage disposal that hums is jammed, not dead, and one that does nothing has usually tripped its reset button — both are minutes to fix. What genuinely needs replacing is a unit leaking from the bottom of the motor housing, because that means the internal seal has failed and water is reaching the windings.
A garbage disposal is a simple machine, which is why so many of them get replaced when they did not need to be. A unit that hums but will not turn is jammed, not dead. A unit that does nothing at all has usually tripped its internal reset button. Both take minutes to resolve.
What is worth taking seriously is a leaking disposal, because water dripping into a sink base cabinet destroys particleboard fast and you often do not notice until the cabinet floor is spongy. Where the leak is coming from tells you whether it is a repair or a replacement.
We repair and install disposals, and — because a disposal problem and a drain problem look identical from above the sink — we check the drain line as part of the call rather than replacing a working unit that was never the issue.
Disposal jammed, leaking or dead?
We will tell you on the phone whether you can fix it yourself. If not, we will come out and price it before we start.
What the symptom actually means
It hums but does not spin
Jammed impeller. The motor is fine and it is trying. Turn it off before it overheats — this is a five-minute fix.
Completely dead, no sound
Tripped internal overload reset, a tripped breaker, a failed switch, or a burned-out motor. In that order of likelihood.
Water under the sink
Where matters. The sink flange, the dishwasher inlet and the drain connection are all repairs. The bottom of the housing is not.
Loud rattling or grinding
Usually a foreign object. Sometimes a broken impeller. Do not run it until someone looks.
Backs up into the other sink bowl
That is a drain problem, not a disposal problem. Replacing the disposal will not change it.
Persistent smell
Biofilm under the splash guard and on the grind chamber walls. Cleanable — and preventable.
What a garbage disposals job includes
Every quote covers the items below. If something is not on this list, it is not in the price — and we will say so before we start.
The drain checked first
Plenty of "bad disposals" are a blocked kitchen branch. We confirm which one you actually have before quoting a replacement.
Jams cleared and overloads reset
If it can be fixed rather than replaced, we fix it — and we will tell you on the phone when it is a ninety-second job you can do yourself.
Leak diagnosed by location
Flange, dishwasher inlet and discharge are all repairs. Only a leak from the motor housing bottom means replacement, and we show you which it is.
Proper mounting and fresh flange seal
New plumber's putty at the sink flange, dishwasher knockout removed where required, and a correct high loop on the dishwasher drain.
Electrical done safely
A proper junction or code-compliant cord and outlet — not taped splices under a wet sink cabinet.
Run under load and hauled away
Tested with the sink full, every joint checked for leaks, and the old unit and packaging leave with us.
Two things to try before you call us
We are genuinely happy to tell you how to fix this yourself, because a service call for something that takes ninety seconds is not a good use of your money and we would rather you call us for the next real thing.
If it hums: turn it off at the switch. Most disposals ship with a hex wrench that fits a socket in the center of the underside — insert it and work the motor back and forth until it spins freely. No wrench? A broom handle against the impeller from above, with the power off, does the same thing. Then find what jammed it and take it out.
If it is dead: look at the bottom of the unit for a small red or black reset button. Overload trips are extremely common. Press it, then try again. If it trips right back, or if the button does not stay in, that is a genuine failure and it is time to call.
One rule above all: never put your hand into a disposal, even with the switch off. The switch is not a guarantee.
When it needs replacing
Leaks tell the story. A drip at the sink flange means the plumber’s putty seal has failed — that is a reseal, not a new unit. A leak at the side inlet where the dishwasher hose connects is a clamp or a gasket. A leak at the discharge tube is a gasket and a few bolts.
A leak coming out of the bottom of the motor housing is different. That means the internal seal above the motor has failed and water is reaching the windings. There is no repair for that, and it is also a shock and short-circuit risk. That unit gets replaced.
Age and horsepower are the other considerations. Ten-plus years on a builder-grade 1/3 horsepower unit means the bearings and the grind ring are worn regardless of what specifically failed. Stepping up to 3/4 or 1 horsepower with stainless components makes a real difference — more grinding torque, fewer jams, noticeably quieter, and better resistance to the corrosion that hard water accelerates.
Leak at the flange
Reseal with fresh plumber’s putty. Repair.
Leak at the dishwasher inlet or discharge
Clamp, gasket or bolts. Repair.
Leak from the motor housing bottom
Internal seal failure. Replace — no exceptions.
Repeated jams on a small unit
Underpowered for how the household actually cooks. Upgrade horsepower.
How a disposal call runs
- 1
Confirm it is the disposal
We check whether the drain line downstream is clear first. Plenty of "bad disposals" are blocked kitchen branches.
- 2
Try the repair
Clear the jam, reset the overload, reseal a flange, tighten a discharge. If it can be fixed, we fix it.
- 3
Straight replacement advice
If it needs replacing we say so and explain exactly why. If it does not, we say that too.
- 4
Install properly
New flange seal, correct mounting, dishwasher knockout removed when required, proper high loop on the dishwasher drain.
- 5
Electrical done safely
Hardwired or cord-and-plug per the existing setup, with a proper connection rather than taped splices under the sink.
- 6
Test and clean up
Run it loaded, check every joint for leaks, and the old unit and packaging leave with us.
What drives the price
Disposal work is straightforward to price and quoted before we start.
- Repair vs replacement
- Clearing a jam or resealing a flange is minimal. A new unit installed is a different number.
- Horsepower and build quality
- 1/3 hp builder units are cheap and short-lived. 3/4 to 1 hp with stainless components costs more and lasts much longer here.
- Whether the plumbing has to change
- Going from no disposal to a disposal, or changing sink configurations, means reworking the drain assembly.
- Electrical condition
- If there is no outlet or switch, or the existing wiring is unsafe, that has to be addressed before installation.
- Whether the drain is also blocked
- If the branch line is clogged, that is separate work with its own price — quoted, not slipped in.

The quote is the price
You hear the number before we start and it does not move afterward. It is the single thing customers mention most in our reviews.
Based at 870 W 15th Ave, not a call centre
Shane, Leo and Justin live in Apache Junction. Most of the city is a ten to fifteen minute drive rather than a cross-valley dispatch.

We publish every review including the two critical ones. A page of nothing but five stars tells you less than an honest one.
Where we provide garbage disposals
Disposal work goes wherever we go. We deliver this from our 15th Ave shop across Apache Junction and Gold Canyon, then out through Queen Creek, San Tan Valley, Mesa, Gilbert, Chandler, Tempe and Fountain Hills.
Further out we cover Florence, Coolidge, Casa Grande, Maricopa, Eloy, Superior and Mammoth, and we are honest about when a small job does not justify the drive. Worth knowing on septic properties around Gold Canyon, Goldfield and rural Pinal County: a disposal meaningfully increases the solids load on the tank, which shortens your pumping interval. We will raise that before installing one rather than after.
