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 Mathis 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 models use a 1/4-inch Allen wrench at the center bottom; Waste King models use a broom-handle approach at the top. Knowing which you have before arriving saves time and prevents the wrong tool damaging the motor shaft.
A disposal that jams once is worth clearing and resetting. A disposal that jams repeatedly, has a seized turntable bearing, emits burning smells, or is over 10 years old is likely approaching motor failure โ and the repair cost of a failed motor exceeds the cost of a new unit.
A disposal installed without properly removing the dishwasher drain knockout plug is a common installation error that floods the dishwasher interior. We check this and correct it if present.
Most disposal calls complete in 30โ60 minutes โ same visit, flat-rate pricing.
If the jam-clearing wrench won't budge the impeller, the motor shaft may be seized rather than just stuck from debris โ we distinguish between the two before recommending replacement.
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.
An unusually loud grinding, rattling, or metal-on-metal sound from a disposal almost always means either a hard object (bottle cap, small utensil, pit from stone fruit) is in the grinding chamber, or an impeller piece has broken and is contacting the shredder ring. We access the grinding chamber safely, remove any foreign objects, and inspect the impeller and shredder ring for damage.
If the slow drain persists after cleaning the drain arm and p-trap, a camera scope of the kitchen drain line is the next step to check for blockage further downstream.
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.
Hums but won't spin, completely silent, grinding noise, leaking, or slow to drain โ each symptom tells our dispatcher which tools and possible replacement units to have on the truck. Knowing the disposal brand is a plus but not required.
The tech identifies the failure type in minutes: jam test at the motor socket, reset button check, power confirmation at the wire connections, leak source tracing. We know what each symptom means and we go straight to confirming it.
You receive a flat-rate price for the repair option and, if relevant, the replacement option with unit cost included. For a simple jam clear, that's a single, low line item. For a failed motor, we show you the new unit cost and installation price together.
After repair or replacement, we run the disposal through a full test: several cycles with water running, check under the sink for any drip at all connection points, and confirm the drain arm clears at a normal rate.

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.
Old disposal stopped working completely โ no hum, nothing. I assumed the motor failed. The tech checked the wiring first โ found a loose wire nut at the junction box under the sink that had vibrated loose over the years. Reconnected the wire, reset the overload button, disposal came right on. Would have been embarrassing if I'd bought a replacement unit. Masters Plumbing Service's thoroughness saved me a few hundred dollars.

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