Same-day garbage disposal repair across Denver
Deft Plumbing handles garbage disposal repair across the Denver metro, and most failures cost far less than the replacement other plumbers quote by default. We diagnose first: a humming unit is usually a jammed impeller, and a silent one is often just a tripped reset button or GFCI. Same-day appointments are typically available during business hours, and you get a written flat-rate quote before we touch the unit. No money down.
We service the full Denver metro and we work on every common brand: InSinkErator (Badger, Evolution), Waste King, Moen, and Whirlpool. If the diagnosis points to a full disposal replacement instead of a repair, we quote both so you can choose. Flat-rate quote in writing before we touch the unit. No money down.
Common garbage disposal repair issues we fix in Denver
Disposal hums but won't spin
Something jammed the impeller, usually a fruit pit, a metal twist tie, or a chicken bone. We free it from the bottom with a 1/4-inch Allen wrench and clear the chamber. Often a 15-minute fix. If the motor overheated and burned out, that's a different conversation, but most hums are mechanical jams.
Completely silent, no power
Either the reset button on the bottom of the unit popped, the GFCI outlet under the sink tripped, or the breaker tripped at the panel. We diagnose in order, starting with the cheapest cause. If it's truly a dead motor, you'll know in under 10 minutes.
Leaking from the bottom of the unit
A leak from the bottom housing usually means the internal seals have failed, and that's a replacement, not a repair. We'll show you exactly where the leak is coming from before we recommend a swap.
Leaking from the dishwasher connection
The rubber hose where your dishwasher drain connects to the disposal cracks over time, especially under the cabinet heat in older Denver kitchens. Quick swap. We carry the hose on the truck.
Slow drain after the disposal
Disposal is fine: the trap or branch line downstream is clogged. We snake the line and clear the buildup. A common Denver pattern: grease and coffee grounds slowly coating the inside of a cast iron drain line in a 1960s ranch.
Rattling, grinding, or metal-on-metal noise
Something hard is loose inside the chamber: a chunk of bone, a screw, a piece of glass. We open it, retrieve it, and inspect for damage to the impeller. If the impeller is intact, you're back in business.
What to expect, start to finish
1. Quick phone triage
Call (720) 880-8064 and describe what's happening: humming, silent, leaking, slow draining. We can often narrow down the cause before we arrive.
2. On-site diagnosis
We inspect the unit, the connections, and the drain line downstream. We identify the actual failure mode, not a symptom but the root cause.
3. Written repair or replacement quote
Whichever direction the diagnosis points, you get a written flat-rate quote before we proceed. If repair is the right call, we quote repair. If the unit is too old or the failure is internal, we quote a replacement with options.
4. Repair on the spot when possible
We carry common parts: splash guards, dishwasher hoses, reset diagnostics. Most repairs complete in the same visit.
5. Test run + cleanup
We run the unit through a full cycle, check for leaks under load, confirm the dishwasher drain is flowing, and clean up the under-sink area before we leave.
6. Written warranty
Every repair comes with a written warranty. You know what's covered and for how long before we drive away.
Why Garbage Disposals Fail Faster in Denver
Two Denver-specific conditions kill disposals before their time. First, hard water. Denver Water's supply tests at 10-15 grains per gallon of hardness in most service zones, classified as 'very hard.' That calcium scales the inside of the disposal chamber, builds up around the impeller bearings, and shortens motor seal life. A disposal that should last 12-15 years in a soft-water city often gives up at year 8 in Denver.
Second, Denver's pre-1980 housing stock often runs disposals on the same circuit as the dishwasher and a few outlets. When the disposal pulls high amperage during a jam, it trips the breaker and people assume the disposal is dead. Half the 'dead' disposals we get called about are actually fine: it's a tripped breaker or a popped GFCI that hasn't been reset.
If your home is in the older zones around Capitol Hill, Park Hill, or the Berkeley area, there's a third factor: cast iron drain lines downstream of the disposal. Grease and ground food slowly coat the inside of cast iron and reduce flow capacity. A slow drain blamed on the disposal is sometimes actually a 50-year-old drain line problem, and snaking the line is the actual fix.

Denver garbage disposal repair questions
Is it worth repairing a garbage disposal or just replacing it?
Depends on the age and the failure mode. A unit under 8 years old with a fixable issue (jam, splash guard, dishwasher hose) is almost always worth repairing. A unit over 12 years old with a leaking housing is usually past its useful life, and replacement is more economical than chasing the next failure. We give you both options in writing so you can choose.
Why is my garbage disposal humming but not spinning?
The motor is getting power but the impeller is jammed by something in the chamber. Common culprits: fruit pits, chicken bones, metal twist ties, or fibrous waste. We free the jam with the bottom Allen wrench, inspect the impeller, and confirm the motor runs cleanly afterward. Usually a 15-30 minute fix.
How long do garbage disposals last in Denver?
Denver's hard water shortens disposal life compared to soft-water cities. Expect 8-12 years for most residential units, with InSinkErator Evolution and Waste King L-Series running on the higher end of that range. If your unit is past 10 years and you've already had one repair, replacement may make more economic sense than a second repair.
Can you repair InSinkErator, Waste King, and Moen disposals?
Yes, we work on every common residential brand. InSinkErator (Badger, Evolution, Pro series), Waste King (Legend, L-Series), Moen GX/GXP, Whirlpool, and KitchenAid. We carry common parts for all of them.
Do I need a permit for a garbage disposal repair?
No, repairs don't require a permit. New installations of a disposal where one didn't exist before may require electrical permitting if a new circuit is run, but in-place repairs and like-for-like replacements don't.
What if the disposal is fine but the sink still backs up?
Then the problem is downstream: usually a partial clog in the P-trap or the branch drain. We snake the line and clear it. Common in older Denver homes with cast iron drains where decades of buildup have reduced flow capacity.
