Kitchen Drain Cleaning for Homes Across the GTA

Kitchen sink clogs are almost always grease, starch and coffee grounds that cooled and stuck. They build quietly over months and then close up in an evening.

  • Advice on what caused it, in plain words
  • Trap pulled and line cabled with the right size of cable
  • Camera run when the clog keeps coming back

Signs it is time to call

Grey water surging up in the other bowl during the dishwasher’s pump-out, a basin that takes minutes to empty, or a sour smell from the drain are classic signs. On double sinks with a disposer, the clog often sits in the shared tailpiece or the trap. When the trap is clear but the sink still backs up, the blockage is in the horizontal arm inside the wall or further down where the kitchen line meets the stack.

  • Dishwasher water backing into the sink
  • Gurgling from the opposite bowl
  • Grease film around the drain basket
  • Basement laundry drain bubbling when the sink empties

On the job, step by step

We clear the cabinet, lay down a tarp and pull the trap to inspect it. Then we feed a cable machine through the trap arm and work it down the line in short runs, feeling for the spongy drag of fat as opposed to the dead stop of an elbow. After the line opens, we flush with very hot water to carry loosened fat past the stack instead of letting it settle again. Where a kitchen line runs long and flat to the stack, as in many split-levels and bungalows, jetting may be the better tool.

GTA houses and what they change

Island sinks in newer homes use air admittance valves that can stick shut and slow drainage. Older Toronto kitchens may drain into galvanized pipe that is half closed with scale. In condos, a kitchen stack serves every unit above and below, so management may need to be involved if the block is in the common riser.

Before you pick up the phone

Ask whether the plumber will check the disposer and dishwasher connection while they are there, and whether they will tell you where the clog was. Call (365) 387-8531 and tell us if you have a second sink in the basement.

Common questions

Will a kettle of boiling water shift grease?

It can move a fresh, small buildup in metal pipe, but it often just pushes grease further down where it sets again. Do not pour boiling water into a clogged sink with PVC traps.
