A clogged bathroom sink is one of the most common plumbing issues Markham homeowners face. Over time, small bits of debris build up inside your drain, slowing the water flow until it stops completely. Understanding the most common causes can help you spot problems early and prevent future blockages.
Hair and soap scum are the biggest culprits behind most slow draining sinks. As strands of hair wash down the drain, they tangle together and trap toothpaste, shaving cream, and other residues. This sticky buildup hardens inside the pipe, creating a stubborn drain blockage. Regular drain maintenance or a professional drain cleaning service in Markham can help keep your bathroom sink flowing smoothly.
The P-trap—the curved pipe beneath your sink—plays a key role in keeping sewer gases out of your home. Unfortunately, it’s also where debris often gets caught. Hair, small items, or grease can settle in the bend, leading to a complete clog or even a water backup. Our experienced plumbers can quickly remove and clean or replace your P-trap if needed. Learn more about how we diagnose tough clogs with camera drain inspection technology.
Markham’s water supply contains natural minerals that can slowly collect inside your sink drain. Over time, these deposits narrow the pipe and cause frequent clogged sink problems. Routine maintenance and professional hydro jetting can safely remove buildup and restore full water flow.
If your bathroom sink is draining slowly or completely blocked, don’t wait for it to worsen—call John The Plumber today for fast, effective clogged bathroom sink repair in Markham.
When you call John The Plumber for clogged sink repair in Markham, you can expect fast, professional service from experienced plumbers who care about your home. We follow a proven step-by-step process to clear the blockage, clean your pipes, and prevent future problems—all while keeping your bathroom spotless.
We start by identifying the exact cause of your clog. Using advanced tools and sometimes a camera drain inspection, our plumber checks the drain for hair buildup, soap scum, or deeper obstructions. This ensures we treat the root of the issue, not just the surface symptoms.
Once we’ve found the problem, we carefully remove it using professional-grade tools such as a drain snake or auger. These tools allow us to clear the pipes effectively without damaging your fixtures. For tougher blockages, we may recommend hydro-jetting to blast away debris with high-pressure water.
The P-trap often collects buildup that slows drainage or causes odors. We remove and clean it thoroughly, checking for any corrosion or leaks. If needed, our team performs sink drain cleaning in Markham to ensure every part of your line is clear and flowing properly.
Before we leave, we test your sink to make sure it’s draining smoothly and that no residue remains. Our plumbers always clean up after the job—we leave your bathroom spotless and your plumbing system working like new.

Have questions about your clogged bathroom sink? You’re not alone! Here are answers to some of the most common questions homeowners in Markham ask our team.
If only your bathroom sink is slow or backed up, the issue is usually a localized blockage. Hair, soap scum, and toothpaste can build up over time and get trapped in the P-trap, stopping water flow. A quick sink drain cleaning or camera drain inspection can pinpoint and clear the clog before it spreads to other drains.
The clogged bathroom sink cost in Markham typically ranges from $150 to $350, depending on the severity of the blockage and the tools required. At John The Plumber, we believe in upfront pricing and provide estimates before starting any work. We also offer same-day service to get your sink draining again fast.
You can try a few safe DIY methods, such as removing visible hair, using a plunger, or pouring a mix of baking soda and vinegar down the drain. However, avoid harsh chemical cleaners—they can damage pipes and fixtures. If the clog persists, it’s best to call a licensed plumber in Markham for professional help.
Frequent clogs usually mean there’s a deeper buildup inside your pipes. Hair, soap residue, or even hard water deposits can restrict flow over time. Sometimes, the P-trap or drain line may be partially blocked or misaligned. Scheduling regular plumbing maintenance helps prevent recurring problems.
Use a drain strainer to catch hair and debris, and avoid washing large items or oily substances down the sink. Run hot water regularly to clear soap buildup, and consider annual drain cleaning in Markham for peace of mind.
