Kitchen Drain Cleaning in Markham

Kitchen lines plug with cooled grease, rice, coffee grounds and dish soap residue that sets like wax inside the trap arm. We open the trap, run a cable through the branch line to the stack, then flush with hot water.

  • Old slip-joint washers swapped if they weep
  • Cable sized to the pipe, not a one-size snake
  • Trap pulled and checked, line flushed at full flow
  • Floors covered before anything is opened

Signs you need kitchen drain cleaning

The sink takes a minute or more to empty. One side of a double bowl backs up when the other drains. Water sits in the bottom of the dishwasher after a cycle. A garburator hums but water pools. Perhaps there is a stale, slightly sweet smell under the cabinet. Each of these suggests fats and food solids have narrowed the pipe between the sink and the main stack.

Our routine on the day

We clear the cabinet, put down a mat and remove the trap first, since a lot of debris settles there. Next a cable goes in at the trap arm and travels toward the stack, using a head that cuts and scrapes rather than simply poking a hole. When the line runs clear, we flush it with hot water to carry loose grease well past the trouble spot.

Reassembly gets new washers where the old ones are tired. We look over the dishwasher's drain loop and its connection to any disposer, because a poor setup there can send water back into the machine.

A small habit: blot oily pans with paper towel ahead of washing them. It does more for your drain than any product on the shelf.

Markham houses and what shapes this job

Many households in Markham cook often and generously, which is a lot of oil and starch for a two-inch drain to carry. Stir-fry oil, soup stock and rice water cool and cling inside the pipe. Over months that layer grows until a single meal tips it over.

Kitchen islands are common in homes from Cathedraltown to Angus Glen. An island sink often drains through a long horizontal run under the floor, with less slope than a wall sink, so it fills with sludge more readily. Older Unionville houses may have a galvanized branch that has rusted rough inside.

If you have a disposer, our garburator dos and don'ts covers what it can and cannot handle. Peels, eggshells and fibrous stalks are frequent culprits.

When cleaning is not enough

Sometimes the camera shows a pipe that has sagged inside the wall or floor, so water and solids settle in the low spot. Cleaning restores flow, though the belly will keep collecting. In that case we will explain whether re-sloping the run is worth doing now or can wait until a kitchen renovation opens things up.

Undersized traps are another common find. Some older kitchens were fitted with a narrow trap that clogs easily, and swapping it for a properly sized one is a small change that pays off for years. We always check the vent too, since a blocked or missing vent makes a sink drain slowly even when the pipe is clean.

Ring us without delay if

Call if the sink will not drain at all, if water appears on the basement ceiling under the kitchen, or if a floor drain gurgles while the sink empties. Those can point beyond the kitchen line to the main, which our general drain cleaning page explains.

Markham note. York Region water is hard, so the inside of older metal drain pipe in Markham carries a rough mineral crust that grease and hair grab onto. Newer ABS drains in Cornell and Wismer stay smoother but sag on long runs.

How the job runs, start to finish

  1. 1

    On the phone

    Explain what the water is doing and where. We ask the age of the house and which valve or breaker to shut while we drive over.

  2. 2

    Drop cloths down

    Floors and cabinets get covered, the water or gas is isolated and the work area is lit.

  3. 3

    Find the failed part

    We open the trap, cleanout, access panel or wall where the fault is, and show you what we found.

  4. 4

    Quote, then work

    We explain what failed and what the fix costs; no cutting starts until you say yes.

  5. 5

    Cut, fit, seal

    Old parts come out, new pipe, valves or fixtures go in, and joints are soldered, pressed, crimped or glued.

  6. 6

    Test and ticket

    We run water, pressure-test or fire the heater, check for drips, clean up and leave a written ticket of what was done.

Quick answers

Will a kettle of boiling water clear a greasy drain?
It may help briefly, but the grease cools further down and settles again. On PVC or ABS, very hot water can also stress joints over time.
Why does my dishwasher back up when the sink clogs?
They usually share the same drain. When the sink line narrows, dishwasher water has nowhere to go and returns to the tub or sink.
