Garbage Disposal Installation & Repair in Toronto & the GTA
Toronto & the GTA • Call 647-784-8448
Garbage disposers fail in a few predictable ways: jammed flywheel, motor humming with no grinding, leaking from the body, or seal leak at the sink flange. Some are repairable; some are past it. Tornado Plumbing & Drains installs, replaces, and repairs garbage disposers across Toronto and the GTA. Garbage disposal repair takes care of jams, tripped resets and flange leaks. When a unit is past saving, we quote garbage disposal installation right there instead of chasing the same fault again.

Part of Plumbing Repairs & Installations in Toronto & the GTA
Book this service when
Book this when the disposer hums without grinding, goes silent, leaks from the body, or leaks at the sink flange, and you want to know whether it is repairable or done.
Common signs
- Hums but does not grind (jammed flywheel).
- Silent when switched on (tripped breaker, internal overload).
- Leaks from the body (failed internal seal, end of life).
- Leaks at the top sink flange (failed mounting seal).
If you're not sure, compare these too
- Drain Cleaning - when the disposer works but the line below it is greased shut
- Sink Installation & Replacement - when the flange seal is failing on a sink that is being replaced

Quick guide and key details
What changes price and scope
- Jam clearing versus replacement.
- Whether a new disposer is supplied.
- Whether the existing electrical connection is reusable.
How a professional visit usually unfolds
1. Identify the issue
Jam, motor failure, leak, or downstream clog. Different fix for each.
2. Repair if possible
Free a jammed flywheel, reset overload, replace mounting seal. Saves a full replacement when feasible.
3. Replace if needed
Internal seal failure, motor failure, or rusted body usually means replacement. Repeat repair on a failing disposal is not cost-effective.
4. Test
Run water with the unit, check leaks, verify operation. Confirms full operation.

Repair, replace, or install — which makes sense for your unit
A jam or a tripped reset on a newer disposer is usually a same-visit fix, but a unit leaking from the motor housing or one near the end of its life is cheaper to swap than to keep chasing. On a new install we set the mounting assembly and sink flange in fresh plumber's putty, knock out the dishwasher inlet plug so the dishwasher drains correctly, and tie the discharge into the P-trap without trapping food in a low spot. If the disposer keeps backing up after it's grinding fine, the fault is usually the branch line, not the unit — see kitchen sink drain cleaning.
Common disposal problems:
- Hums but does not grind (jammed flywheel).
- Silent when switched on (tripped breaker, internal overload).
- Leaks from the body (failed internal seal, end of life).
- Leaks at the top sink flange (failed mounting seal).
- Slow drain through the disposal (clog downstream).
- Rust visible on the disposal body.
What's included
- Diagnosis: test the motor, reset button, and overload, free a jammed flywheel from the bottom hex, and check the splash baffle, dishwasher inlet, and discharge for the actual fault
- Repair where viable: clear jams, replace a failed sink-flange seal or mounting gasket, reseat the discharge tube, and reconnect the dishwasher drain loop
- New install or swap: remove the old unit, fit a new mounting assembly and sink flange with fresh plumber's putty, hang the disposer, and connect the P-trap and dishwasher line
- Electrical safety: confirm the unit lands on a switched, GFCI-protected circuit and the air switch or wall switch operates correctly
- Leak and run test: fill and drain the bowl, run the disposer under load, and verify no weeping at the flange, body, or discharge before we leave
- Cleanup: haul away the old disposer and packaging and wipe down the under-sink area
- Written 25-year workmanship warranty on the installation labour
Disposal cost
Jam clearing and minor repair stay in the lower range. Replacement depends on whether a new disposer is supplied and whether the existing electrical connection is reusable.
What to share when you call
- Symptom (silent, humming, leaking).
- Brand and approximate age of the disposer.
- Whether you have a replacement disposer ready.
- Whether the existing electrical is hard-wired or plug-in.
- Photos under the sink.
- Whether the dishwasher drains through the disposer.
Toronto context
Disposal installs in Toronto kitchens hinge on the dishwasher tie-in and the branch drain capacity. Lower-horsepower units (1/2 HP) suit small households; higher-HP grinders are usually overkill and harder on the trap. We size to the actual cooking pattern, not the unit price.
What to confirm before approving disposal work
- Repair vs. replace should be honest — repeat seal repair on aged disposers usually means it is time to replace.
- Mounting hardware and gasket should be replaced with the new disposer.
- Dishwasher drain plug should be removed when applicable.
Useful info on the call: symptom, age, and whether a replacement is on hand.
Frequently asked questions
How long do garbage disposers last?
Typically 8 to 12 years for residential use. Heavy use or hard food shorten that. Internal seal failures are usually a sign of end of life.
Should I get a more powerful disposer?
More HP grinds finer but also costs more. For most households, 3/4 HP is the sweet spot.
Can I install one myself?
If the existing electrical is set up, many homeowners do. First-time installs that require switched outlets and new plumbing are usually better done by a plumber and electrician.
Will a disposal help my drain?
It grinds food before it enters the drain — but grease, fibrous material, and starchy peels can still clog the line. Use it correctly to keep the kitchen drain working.

August 2022“Tornado Plumbing and Drains did an excellent job replacing my old drains and correcting some very old plumbing in my old house in only 2 days. Peter was very thorough in evaluating and explaining in detail the problems with the drains and how they would be repaired. He was extremely patient in answering all of my concerns. The team showed up on time, protected the work areas and did an excellent job with the final clean-up. They are assisting me with the rebate for the valve also. The cost for the work was very reasonable and several thousand dollars less than two other companies. I have already recommended Tornado to several friends and recommend them without reservation.”

May 2025“I highly recommend Serhiy. I have used him several times, and he always does quality work. He recently replaced a toilet, faucet, and house shut-off valve, all of which had leaks and were faulty. He knows what he is doing - He is licensed, experienced, efficient, and pays attention to details. His pricing is very fair, and unlike some others, the price doesn't go up based on the area you live in. All this is hard to find in professionals. Someone honest (he won't fix things that don't need repair to create work) and who takes pride in a job well done. I will definitely call him again for future plumbing needs.”
