Blocked Drains

Blocked Drain Repair in Oshawa, Whitby & Durham Region

A fully blocked drain is more than a slow inconvenience. It can force wastewater back into your home, create unsanitary conditions, and put real strain on the surrounding pipes if it’s not cleared properly. Tree roots, grease, and foreign objects are the most common causes, and each one needs a different fix, which is why a proper diagnosis matters more than just running a snake down the line and hoping for the best. We clear blocked drains for homes and businesses throughout Oshawa, Whitby, and Durham Region.

Common Causes of Blocked Drains

Tree roots growing into aging sewer or drain lines, especially common in older neighbourhoods with mature trees
Grease and soap buildup that narrows the pipe over time until almost nothing can pass through
Foreign objects flushed or washed down a drain, from wipes to toys to construction debris
Collapsed or misaligned pipe sections, often in older clay or cast iron piping
Mineral scale buildup in hard water areas, which gradually reduces the interior diameter of the pipe

How We Clear a Blockage

As licensed plumbers, we use professional-grade equipment, including drain snakes and hydro-jetting where appropriate, to clear tough blockages completely rather than just pushing them further down the line. Where the cause runs deeper than a simple clog, we offer solutions like slab leak detection and pipe replacement so you’re addressing the root problem instead of calling us back for the same blockage in a few months.

When It's More Than One Drain

If more than one fixture is backing up at once, for example a toilet backing up when you run the washing machine, the blockage is likely further down the line, possibly in the main sewer line rather than an individual drain. That’s a different problem than a single slow sink, and it’s worth a proper inspection with a camera rather than repeated clearing of individual fixtures.

Preventing Future Blockages

Once a blockage is cleared, a few habits go a long way toward keeping it that way: avoiding pouring grease down the kitchen sink, using drain covers to catch hair in the shower, and being mindful of what gets flushed. For homes with a history of tree root intrusion, periodic camera inspection can catch a developing blockage before it becomes a full backup.

Frequently Asked Questions

How much does it cost to clear a blocked drain?

It depends on the cause and location of the blockage. We start with a $79 inspection to identify exactly what’s going on, which is applied to the cost of the repair if you move forward.

Can I clear a blocked drain myself before calling a plumber?

A plunger is fine for a simple, single-fixture clog. We’d caution against chemical drain cleaners, though, since they can damage older pipes and don’t address blockages caused by tree roots or collapsed sections, which are common causes of recurring blockages.

How do I know if it's a blockage or a bigger sewer line problem?

If clearing the drain doesn’t fix it for long, or if multiple fixtures are affected at once, that usually points to something happening further down the line. We can run a camera inspection to see exactly what’s going on before recommending a fix.
