Downspout Cleaning & Unclogging in Toronto & the GTA

A clean eavestrough still overflows if the downspout is packed. Northline clears and flushes residential downspouts throughout Toronto, Brampton and the GTA so rainwater actually leaves the roofline and gets away from your foundation.

Most blockages sit in the elbow at the top or where the pipe meets the ground — both easy to miss from a ladder and both something we check on every visit.

What we do

  • Test each downspout with water to find where it is restricted
  • Open and clear elbows, joints and ground-level outlets
  • Flush the full run until the flow is clear and steady
  • Check that extensions carry water away from the foundation
  • Report any damaged, disconnected or undersized sections we find

Why blocked downspouts matter in an Ontario winter

When a downspout cannot drain, water backs up into the trough and sits there. In freeze-thaw cycles that standing water expands, pulls hangers loose and forms ice dams at the roof edge. On the ground, overflow saturates the soil beside the foundation, which is the usual first step toward a damp basement. Clearing downspouts in late fall is cheap insurance against all of it.

Usually booked with eavestrough cleaning

Downspout clearing is included in our full eavestrough service, but we also do it as a standalone call when only one corner of the house is overflowing. Not sure which you need? Send a photo with your quote request and we will tell you honestly.

Downspout Cleaning FAQs

How do I know my downspout is clogged?

Run a hose into the top of the trough near the downspout. If water backs up or trickles out the bottom instead of running out steadily, there is a blockage — usually in the upper elbow.

Can you clear underground drain lines?

We clear the downspout itself and the visible outlet. Buried drain lines that run under a driveway or into a weeping system need a drain specialist, and we will tell you if that is what you are looking at rather than guessing.

Is downspout cleaning included with eavestrough cleaning?

Yes. Every full eavestrough clean includes flushing the downspouts, because clearing one without the other does not fix the drainage.

How often should downspouts be cleared?

Once a year for most GTA homes, and twice a year if your roof sits under mature trees.
