If you’ve got a slow-draining sink or standing water that won’t go down, you’re not alone. Clogged sinks are one of the most common plumbing issues for homeowners in Markham — and they can be caused by more than you think. Understanding what leads to a drain blockage can help you prevent future problems and know when to call a professional.
Here are some of the most frequent causes we see:
Grease and Food Buildup: Cooking oils, fats, and food scraps harden inside your pipes over time, creating stubborn grease buildup in pipes that narrows the flow.
Soap Scum and Hair: In bathrooms, soap residue mixes with hair to form sticky clogs that make your bathroom sink clogged and slow to drain.
Foreign Objects or Debris: Items like dental floss, small toys, or even paper products can easily get trapped, blocking the drain completely.
Pipe Corrosion or Mineral Buildup: Older homes in Markham often have aging plumbing, which can collect rust or mineral deposits that reduce water flow.
Faulty Garbage Disposal: When your disposal jams or fails, it can send food waste and debris back into your kitchen sink, causing a major backup.
💡 Did You Know?
You can help prevent a clogged sink by avoiding grease disposal down the drain, using a strainer to catch debris, and running hot water weekly to flush buildup.

We know plumbing problems can be frustrating — especially when your sink won’t drain or keeps clogging up. To help you out, our team at John The Plumber has answered some of the most common questions homeowners ask about how to unclog a sink in Markham and when it’s time to call in the pros.
A slow-draining kitchen sink is almost always caused by grease and food buildup. Over time, oils, fats, and leftover food particles harden inside your pipes, restricting water flow and causing stubborn blockages. Even if the water eventually drains, the clog will continue to grow until it completely blocks your sink. The best solution is professional drain cleaning in Markham to remove buildup safely and restore full flow.
DIY methods like baking soda and vinegar can help with light buildup or minor clogs, but they’re rarely a permanent fix. If your sink keeps backing up or the clog returns after a few days, it’s time to call a professional. Our technicians use safe, effective methods — like hydro-jetting and drain snake services — that clear even the toughest blockages without damaging your pipes.
Most bathroom sink clogs are caused by a mix of hair, soap scum, and toothpaste residue. These materials cling to pipe walls and slowly narrow the drain. For a quick and reliable fix, our team offers clogged bathroom sink repair in Markham to clear the blockage and prevent it from coming back.
If your sink keeps clogging, you hear gurgling sounds, or water backs up in nearby drains, it’s time to call a pro. These signs may mean a deeper issue in your main drain line or a developing drain backup. The best plumber for clogged drains in Markham can quickly diagnose and fix the issue before it turns into a bigger plumbing problem.
The price can vary depending on the severity of the clog and the tools required, but most sink unclogging services in Markham fall within a reasonable range. For an accurate quote, contact our team — we’ll assess your issue and provide honest, upfront pricing.
