A slow-draining sink or standing water in your shower might not seem like a big deal — until it becomes a full-blown blockage. Clogged drains are one of the most common plumbing problems for homeowners in Sarnia, and if left untreated, they can lead to bad odours, leaks, or even pipe damage.

At Custom Plumbing Sarnia, we’ve been clearing and repairing drains for local homeowners since 1991. Here’s what causes most drain clogs, how to fix them, and when to call in the pros.


What Causes Clogged Drains?

Understanding the cause of your drain problem is the first step to preventing it in the future. Here are the most common culprits:

  • Grease and food debris: Oils, fats, and food scraps solidify inside kitchen drains.
  • Hair buildup: In showers and bathroom sinks, hair combines with soap scum to create stubborn clogs.
  • Foreign objects: Wipes, paper towels, and hygiene products don’t break down like toilet paper and can quickly block pipes.
  • Soap residue: Hard water and soap create residue that builds up over time.
  • Tree roots: In older homes, tree roots can invade underground drain lines, restricting flow or causing total blockages.

Even minor buildup can restrict water flow, eventually leading to a backup or costly repair.

How to Fix a Clogged Drain (Safely)

Before you reach for a chemical drain cleaner, try these safer, plumber-approved solutions:

1. Boiling Water and Dish Soap

For mild clogs, pour boiling water mixed with dish soap into the drain to help dissolve grease.

2. Plunge It

Use a sink or toilet plunger to dislodge simple blockages. Make sure to cover any overflow holes for better suction.

3. Use a Drain Snake

A manual or electric auger can help remove hair and debris from deeper in the pipe.

4. Skip the Chemicals

Many over-the-counter cleaners are harsh and can corrode your pipes — especially older ones. If the clog persists, it’s time to call in a professional.


When to Call a Professional Plumber

If your drains are constantly clogging, backing up, or emitting bad odours, the problem may be deeper in your system. That’s where Custom Plumbing’s expertise comes in.
