Emergency Main Drain Unclogging in Oakville – Causes, Fixes, and Prevention
At 17 Plumbing & Construction Design Ltd., we recently handled an emergency call for a main drain clog at a home in Oakville. The client reported strong sewage odours throughout the house. Upon arrival, our licensed plumbing team performed a full inspection and unclogged the main drain using a heavy-duty snaking machine. The situation was resolved before it escalated into flooding or water damage.

What Is a Main Drain and Why It Matters
Your main drain (or main sewer line) is one of the most critical parts of your plumbing system. It carries wastewater from all your home’s fixtures—sinks, toilets, bathtubs, washing machines—into the municipal sewer system.
When this line becomes blocked, it doesn't just affect one area—it backs up your entire home. That’s why early signs like a bad smell from the basement drain or slow draining in multiple fixtures should never be ignored.

Common Causes of Main Drain Clogs in Oakville Homes
At 17 Plumbing, we’ve dealt with hundreds of these emergencies. The most common culprits behind a main drain clog in Oakville include:
- Grease Buildup: Over time, grease poured down the kitchen sink hardens and clings to the pipe walls, restricting flow.
- Non-Flushable Materials: Flushing paper towels, hygiene products, or even so-called “flushable wipes” often leads to serious blockages.
- Tree Root Infiltration: In older Oakville neighborhoods, large trees have roots that grow into clay or cast iron sewer lines, cracking and clogging them.
- Pipe Scaling or Corrosion: Hard water causes mineral deposits that can narrow pipes internally.
- Collapsed or Misaligned Pipes: Due to shifting soil, poor installation, or age-related damage, pipes may collapse or sag, trapping waste.
Knowing the root cause of your drain issue helps determine the best long-term solution—whether snaking, hydro-jetting, or full sewer line replacement.
Our Emergency Response: Main Drain Snaking in Action
In our recent case, the homeowner noticed that the smell had gotten progressively worse over 24 hours, and water began pooling in the furnace room. This was an emergency.
We quickly assessed the plumbing layout and used a heavy-duty electric drain snake to access the main line. Our equipment was able to cut through thick grease and debris buildup. Once the clog was cleared, we ran water from multiple sources to confirm proper flow through the system.
The smell dissipated, and the homeowner had full use of their plumbing again — within hours of calling.
Why You Shouldn’t Ignore Sewer Smells in Your Home
A sewer smell in your home isn’t just annoying — it’s a warning sign.
Sewage gases can be dangerous if they build up, and stagnant water from clogs can become a breeding ground for bacteria and mold. Here's what to watch for:
- Foul odours from floor drains or laundry rooms
- Slow flushing toilets or drains bubbling when other fixtures are used
- Water backups in basement drains or lower-level bathrooms
- Gurgling sounds from sink or bathtub drains
If you’re experiencing one or more of these, call a licensed plumber in Oakville immediately.
Preventative Tips to Avoid Future Main Drain Clogs
Nobody wants to deal with the stress and cost of emergency plumbing. Here’s how you can reduce the risk of a main drain clog:
- Never pour grease or oil down the sink — dispose of it in a container.
- Only flush toilet paper — avoid wipes, even “flushable” ones.
- Use drain screens in showers and sinks to catch hair and food.
- Schedule annual drain maintenance to remove buildup early.
- Consider a drain camera inspection every few years to assess pipe condition.
- Install a backwater valve — it prevents sewer backups from flowing back into your home.
With regular upkeep, you can avoid expensive emergency visits and protect your home’s plumbing system.
