A garbage disposal that's been making grinding sounds for months before stopping entirely often has a seized bearing or cracked impeller โ signs the motor isn't worth repairing. Our techs in Mapleton tell you honestly whether a repair or a same-day unit swap makes more financial sense.

Garbage disposal failures have specific, diagnosable causes. Our techs don't just swap units โ they identify what failed and whether repair or replacement is the right call for your situation.
Hum but no spin: jammed impeller. No sound at all: tripped thermal overload or failed motor. Intermittent operation: loose wiring at the switch or disposal unit. Continuous drain from the sink collar: failed sink flange gasket. Leak from the side: dishwasher drain hose connection or internal body crack. We trace the symptom to the specific cause before recommending any solution.
InSinkErator (Badger, Badger 5, Compact, Evolution series), Moen GXS/GX series, Waste King, KitchenAid, and Whirlpool disposals all mount differently and have specific jam-clearing procedures. We know the mounting assembly for each brand and carry the correct jam-clearing wrench sizes.
We give you the actual cost comparison. If clearing the jam and pressing the reset button fixes it, that's what we do. If the motor has failed, we show you the replacement options and install same-day.
A disposal isn't an isolated appliance โ it connects to the sink drain, the dishwasher drain (if present), and the drain arm leading to the p-trap. We inspect the full connection set during any disposal call: drain arm slope, dishwasher drain knockout (if a dishwasher is being added), and p-trap connection integrity.
From a simple jam clear to a full replacement with drain reconnection, here's how we handle each garbage disposal scenario in Mapleton, MN.
A disposal that hums with no rotation has a jammed impeller plate โ the spinning plate has been stopped by a bone fragment, a piece of silverware that fell in, or hard food buildup around the shredder ring. We use the jam-clearing wrench at the center motor socket to manually rotate the impeller free, remove any obstruction from the grinding chamber, and press the thermal overload reset button before testing.
If power is confirmed at the disposal and it still won't start after a reset, the motor is failed. We then move to the replacement conversation with honest cost comparison.
We identify the leak source before recommending any repair. A sink collar re-seal is a 30-minute job. A unit with a cracked body has no cost-effective repair and warrants replacement.
If the turntable bearing has failed โ indicated by a loud rumbling throughout operation rather than specific impact sounds โ that's an internal motor wear failure that warrants replacement.
A disposal that grinds normally but drains slowly has a blockage in the drain arm or p-trap โ not an internal disposal problem. Food particles and grease accumulate in the short drain arm between the disposal outlet and the p-trap. We disconnect and clean the drain arm, clear any p-trap buildup, and reinstall with clean connections.
When the motor has failed, the unit body is cracked, or the existing unit is underpowered for the household's use pattern, we replace the disposal with a new unit matched to the sink drain configuration. We carry 1/2 HP, 3/4 HP, and 1 HP units from InSinkErator and other major brands on our trucks for same-day installation.
No guesswork โ we diagnose before we quote, and quote before we start.
If you know the disposal is over 10 years old, tell us โ that changes how we approach the repair-vs-replace conversation upfront.
For leaks, we dry the area completely and run a short test cycle to confirm exactly which connection is dripping.
You decide. We don't upsell replacement when repair is the right answer, and we don't push a cheap repair that won't hold on a unit that's genuinely at end of life.
We leave the cabinet dry and the disposal running quietly. If a dishwasher drain hose was involved, we run a dishwasher cycle to verify no backup occurs.

The disposal under our kitchen sink was 12 years old and started leaking from the bottom โ which the tech explained is always an internal seal failure, not a repairable condition. He had a replacement 3/4 HP InSinkErator on his truck, installed it in about 45 minutes, and the kitchen is back to normal. Old unit got pulled, new unit tested clean, no leaks at any connection.
After we added a dishwasher, it started backing up every cycle. Masters Plumbing Service found the problem immediately โ the previous installer had forgotten to knock out the dishwasher drain plug inside the disposal inlet. The plug was blocking the drain port. Two-minute fix. The tech also tightened the dishwasher drain hose clamp, which was loose. Never had another backup.
Disposal leaking from the sink collar area. Previous owner had installed it with silicone instead of plumber's putty at the flange โ silicone doesn't hold the mounting pressure correctly and had separated. Tech re-seated the flange with putty, re-tightened the mounting ring, and the leak stopped. Tested with a full minute of running water. All clear.

Our trucks carry replacement disposal units in common horsepower ratings for same-day installation when the motor has failed.

Our disposal techs in Mapleton, MN carry the tools and replacement units to resolve any disposal problem same visit. Flat-rate pricing, honest repair-vs-replace guidance, and no unnecessary upselling.
