Bathroom Drain Unclogging in Markham

Most bathroom clogs are made of the same three things: hair, soap and toothpaste. They are stubborn, though rarely complicated, and the fix should leave the drain better than before.

  • Hair, grease and scale pulled out where you can see it
  • Old slip-joint washers swapped if they weep
  • Trap pulled and checked, line flushed at full flow
  • Floors covered before anything is opened

Signs you need bathroom drain unclogging

You are standing ankle-deep before the shower is over. The vanity sink holds water while you brush your teeth. The tub drains with a slow swirl and a gurgle. A faint mildew smell drifts up from the overflow. Clogs in bathrooms usually build slowly, so the change can be easy to miss until one morning it is suddenly obvious.

Our routine on the day

We pull the stopper or strainer first, since a surprising amount of hair wraps around the linkage just below. Next comes a small auger through the drain or overflow to reach the trap and the branch line. For pop-up sink stoppers, we clean and adjust the pivot rod so it stops catching debris. Once water runs freely, we fill the sink or tub and pull the plug, watching for full flow.

If a stopper or overflow plate is cracked or corroded, we will point it out and replace it only if you ask.

Cheap insurance: a simple mesh hair catcher on the shower drain costs little and saves most of these visits.

Markham houses and what shapes this job

Hard York Region water leaves soap scum that binds hair into a felt-like plug. Glass shower enclosures with linear drains, popular in newer homes around Cornell and Box Grove, need a slightly different approach, as the grate and channel must come out cleanly.

In older two-storey homes in Raymerville or Royal Orchard, upstairs tubs may drain through original metal pipes with a rough interior. Basement bathrooms added later sometimes connect to an ejector pump, so a slow basement shower can be a pump issue rather than a clog. Our basement bathroom rough-in page covers how those setups connect.

Toilets are their own topic. If the toilet is the slow one, see toilet repair.

What a visit looks like

We lay a drop cloth over the tub or vanity, keep tools off your counters and wipe down the fixture afterwards. Hair and debris we pull out leaves with us in a sealed bag. Most single-fixture visits are short, and if we see something worth knowing, such as a loose tub spout or a slow-dripping shower valve, we mention it before we go.

When more than one bathroom shares a branch line, we test each fixture after clearing, not just the one that was slow. That way any narrowing further along is caught on the same visit instead of turning into a second appointment a week later.

Ring us without delay if

Call promptly when water rises in the tub as you flush the toilet, or when more than one bathroom drain is slow. That pattern points to a blockage further down the shared line, not a hair clog at the fixture. A quick visit then can save a messier one later.

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

Do enzyme cleaners work on bathroom drains?
They can help with light build-up over weeks, but they will not clear a solid hair plug. Mechanical removal is faster and more reliable.
Why does my sink smell even when it drains?
The overflow channel collects grime and can hold odour. Cleaning it, or a dried-out trap in a rarely used sink, is usually the answer.
