A clogged kitchen sink can stop your household in its tracks. From washing dishes to cooking, everything becomes a hassle when your kitchen sink drain starts to back up or drain slowly. At John The Plumber Markham, we’ve helped hundreds of homeowners clear their sinks — and most clogs come down to a few common causes.
One of the biggest reasons for a slow draining sink is grease buildup. When hot grease or oil goes down the drain, it cools and hardens along your pipes, trapping food particles and causing serious blockages over time. Our experts use advanced drain cleaning services and safe techniques to clear grease clogs completely — without damaging your pipes.
Even with a garbage disposal, food buildup and coffee grounds are common culprits. These materials clump together and settle in the drain, making it hard for water to flow freely. If your kitchen sink is backing up, it may be time for a professional clogged drain cleaning in Markham.
Markham’s hard water often leaves behind soap scum and mineral buildup inside your pipes. Over time, this creates a sticky layer that catches debris and causes blockages. Regular maintenance and hydro jetting can help keep your pipes clean and flowing smoothly.
Sometimes, the problem isn’t buildup — it’s an object that doesn’t belong in your sink. Forks, straws, or even small toys can slip into the drain and cause stubborn clogs. If that happens, our team can use a camera drain inspection to locate and remove the obstruction quickly.
If you’re tired of dealing with recurring sink clogs, check out our helpful guide on how to prevent a kitchen sink clog (coming soon to our blog). Or, skip the stress and book a same-day kitchen sink repair today.
When you call John The Plumber Markham for sink clog repair, you’re getting a professional, step-by-step service that’s fast, clean, and effective. Our drain cleaning service in Markham is designed to get your sink flowing again the same day — with no mess and no stress.
Here’s what you can expect when our friendly plumbers arrive at your door:
We start by locating the problem. Using advanced inspection tools — including camera drain inspections — we determine what’s causing your kitchen sink to clog. Whether it’s grease buildup, food debris, or a deeper issue, we’ll find it fast.
Depending on what we find, our licensed plumbers will use drain snaking or hydro jetting to remove the blockage. Both methods are powerful and safe for your pipes. Hydro jetting blasts away years of buildup, while snaking is ideal for smaller, localized clogs.
Once your drain is clear, we test the water flow to make sure everything is working perfectly. Then we tidy up our workspace, leaving your kitchen spotless — as if we were never there.
Before we leave, our experts share easy maintenance tips to help you avoid another clogged kitchen sink. We’ll also recommend a preventative drain cleaning schedule to keep your pipes in top shape year-round.
At John The Plumber, we use modern equipment, eco-friendly cleaning solutions, and time-tested methods to ensure fast, long-lasting results.

Have questions about your clogged kitchen sink? You’re not alone! Our Markham plumbers have answered some of the most common questions homeowners ask about kitchen sink clogs, slow drains, and plumbing repairs.
A slow-draining sink usually means buildup inside your drain pipes. Over time, grease, soap scum, and food particles stick to the pipe walls and narrow the passage for water. Try running hot water and dish soap to loosen light buildup — but if that doesn’t help, it’s best to call a drain cleaning expert in Markham for a thorough cleaning.
Most kitchen sink clogs come from everyday use — things like grease, coffee grounds, or fibrous foods such as celery and potato peels. These materials don’t break down easily and can create stubborn blockages. For tough or recurring clogs, our team offers camera drain inspections to find the root cause fast.
The cost to unclog a sink in Markham depends on the severity and location of the blockage. Minor clogs are usually quick and affordable to fix, while deeper or more complex issues might require hydro jetting or advanced tools. The best way to know is to contact us for a quote — we offer upfront, transparent pricing before any work begins.
You can try some basic DIY steps, like plunging the sink or using a mixture of baking soda and vinegar. However, chemical drain cleaners can damage pipes and should be avoided. If the clog doesn’t clear after a few tries, it’s safest to call a licensed plumber in Markham to avoid worsening the problem.
If your sink keeps backing up, it might be a sign of a bigger plumbing issue — such as a drain backup or blockage deeper in your system. Avoid using the sink and call John The Plumber Markham for same-day service. We’ll diagnose the problem and make sure it’s fixed for good.
