Water drains into a sink.

Drains don’t just clog, they ruin weekends, flood basements, and cost homeowners thousands. At FlowPro, we see it every week in Montreal: homes in Rosemont, Laval, and the Plateau struggling with backups that could have been avoided. This guide cuts through the fluff. No gimmicks. Just expert insight to help you handle clogs, prevent disasters, and know exactly when to call in the pros.

Why Drains Clog in Montreal Homes

Whether you live in a triplex or a century-old home, your plumbing isn’t immune. Montreal has unique challenges:

  • Tree roots searching for water infiltrate clay or older cast iron pipes.

  • Grease and food waste solidify in narrow kitchen drains.

  • Soap scum and hair create stubborn buildups in tubs and showers.

  • Freeze-thaw cycles lead to pipe movement and misalignments underground.

Add in old infrastructure and winter salt runoff, and it’s a recipe for backups.

Top Signs You’ve Got a Clog Brewing

  • Slow-draining water in your sink or tub

  • Gurgling noises when flushing or draining

  • Bad smells rising from the drain

  • Water backing up into basement fixtures

Pro Tip: If you’re hearing glug-glug sounds after doing laundry or running the dishwasher, your main drain line might be partially blocked.

DIY Fixes That Actually Work

Plunger: Basic but effective for toilets and sinks.

Boiling water + dish soap: Great for grease-based clogs in kitchen sinks.

Baking soda + vinegar: Let it fizz for 20 mins, then flush with hot water.

Drain snake or auger: Reach deep into pipes and break up hair or roots.

Avoid: Overusing chemical drain cleaners. They corrode your pipes and often just push the clog further down.

Tools That Professionals Use

  • Camera Inspection: We send a camera into the line to locate blockages and cracks.

  • Hydro Jetting: High-pressure water jets blast out years of grease, sludge, or root intrusion.

  • Pipe locators: For pinpointing underground trouble spots before digging.

These tools save time, money, and prevent guesswork.

When DIY Isn’t Enough

Call FlowPro if:

  • You’ve tried everything and water still won’t drain.

  • You have frequent clogs in the same spot.

  • You see water backing up in the basement.

  • There’s a sewage smell indoors or outdoors.

We handle emergency calls 24/7—yes, even Sundays at 2AM.

Preventative Measures to Keep Drains Clear

  • Install drain screens in sinks and showers.

  • Don’t pour grease, oil, or coffee grounds down the sink.

  • Flush your drains monthly with boiling water + baking soda.

  • If you have large trees on your property, schedule a yearly camera inspection.

Homeowner Tip: Bundle your inspection with hydro jetting once a year for peace of mind.
