Clogged Kitchen & Bathroom Sink Repair

A sink that drains slowly today is often a sink that will not drain at all tomorrow. We clear clogged kitchen and bathroom sinks fast, and make sure the clog does not come right back.

Overview

Fast relief for clogged kitchen and bathroom sinks

A clogged kitchen sink is one of the most common, and most disruptive, calls we get. Years of grease, food particles, and coffee grounds build up inside the trap and drain line until water stops moving altogether. We clear the blockage completely, run a full sink of water through the line to confirm it drains, and tell you what caused it.

Bathroom sinks clog differently, usually hair, soap scum, and toothpaste residue collecting in the trap and just past it. It is a quick fix for us, but one that is easy to get wrong with store-bought drain chemicals, which can damage older pipes without ever clearing the real blockage.

If your sink is draining slowly, gurgling, or backing up into the other side of a double basin, that is worth a call before it becomes a full clog. We will clear it, explain what caused it, and tell you honestly whether it is a one-time fix or a sign that the drain line needs a closer look. If more than one fixture is slow at once, that is usually a main line clog rather than a sink problem, and for tubs, showers and floor drains see our drain cleaning service. Our guide explains why a drain keeps clogging.

Hard municipal water across much of York Region leaves soap scum that grease sticks to, so kitchen clogs here often come back unless the line is fully cleared. In older homes in Thornhill, North York and Aurora we often find corroded metal trap arms and drain branches that have narrowed over time; when cabling will not hold, we tell you and quote replacing that section rather than repeating the clean.

A sink that drains slowly shows us where the buildup is collecting while the line still moves, which is the easiest point to clear it completely.
Our Process

How It Works

What our technician actually does at a clogged sink, and what changes the price.

1

Pull The Trap First

A kitchen trap packed with grease tells us the clog is local. A clean trap with water standing behind it means the blockage is in the trap arm or the branch line inside the wall. On a double basin we check the baffle tee and the garburator or dishwasher connection, because that junction catches food before the trap does.

2

Clear It By Hand And Cable

Trap and trap arm we clean by hand. Anything past the wall gets a hand auger or a small drum machine through the trap arm or the cleanout, run until the cable comes back clean and the line takes a full sink without hesitating.

3

Reassemble And Load Test

New slip washers on the trap, a check of the tailpiece and the dishwasher hose, then we fill both basins and let them go at once. If it gurgles or hesitates under that load, the problem is further down and you hear it from us before we leave, not after the next clog.

4

Explain The Cause And The Price

You get the cause in plain terms and a written price for anything further before we do it. Price depends on whether the clog cleared at the trap or the branch line had to be cabled, whether a corroded trap or drain arm had to be replaced, access under a pedestal or wall-hung vanity, and whether a camera is warranted.

Common Questions

Clogged Sink Questions, Answered

What homeowners across York Region ask us about clogged kitchen and bathroom sinks.

What usually causes a clogged kitchen sink? +
The most common culprits are grease and cooking oil that solidify inside the pipe, food particles including starchy foods and coffee grounds, and soap residue. Over time these build up into a blockage that store-bought drain cleaners often cannot fully clear.
Are liquid drain cleaners safe to use on a clogged sink? +
We generally recommend against them. Chemical drain cleaners can be harsh on older pipes, especially in homes with galvanized or aging plumbing, and they often only clear part of the blockage, meaning the clog comes back within days while the chemical sits in your pipes.
Why does my bathroom sink drain slowly even after I clean it? +
Hair and soap scum tend to collect just past the P-trap, in a spot that is hard to reach with a basic hardware-store drain snake. A professional cleaning clears the full length of that section, not just the visible part.
Can a clogged sink be a sign of a bigger drain problem? +
Usually not, most sink clogs are isolated. But if several fixtures are slow at the same time, or a sink backs up when you flush a toilet, that points to a blockage further down the line that is worth having looked at.
Why does my kitchen sink back up when the dishwasher runs? +
The dishwasher pumps its water into the sink tailpiece or the garburator, so a partly blocked trap or branch line past that point sends the water up into the basin. Clearing the line usually stops it. If the dishwasher hose has no high loop or air gap, we add one so a future clog cannot push dirty water back into the dishwasher.
Do you replace a corroded trap or drain arm? +
Yes. A metal trap or trap arm that has rusted thin often leaks as soon as it is disturbed, so if we find one we show you and give you a price for replacing it before we do the work.
