Local knowledge

How Thornhill streets treat their gutters

Split-levels put an extra load on Thornhill downspouts. When an upper roof drains onto a lower one, the lower downspout carries two roofs' water and debris, so it is usually the first to clog on the house, and a blocked one sends overflow down the wall beside the lowest floor. On lots under the oaks of Royal Orchard and Bayview Glen, or backing the East Don valley, acorns and oak leaves pack elbows into a solid plug.

Every cleaning includes the downspout flush and a flow test, and a split-level cleaning is $399 for a detached home on the 2026 matrix. We clear blockages at the top or the elbow on the same visit, and where a spout discharges beside the foundation, we add or adjust an extension so water leaves the house. Underground drains are the one thing quoted separately.

How we run it

The Thornhill operation, step by step

  1. 1

    We flush

    Every cleaning ends with a downspout flush. If water backs up, there is a clog to clear.

  2. 2

    We clear the clog

    We work the blockage loose from the top or the elbow until the spout runs free.

  3. 3

    We confirm the exit

    We check that water leaves the spout and heads away from your home, not toward the basement.

By the tallest working height. Most split-levels need two-storey ladders at the back or side, so they price as two storeys: $399 for a detached home on the 2026 matrix. You see the exact number before you book.

Yes. Every cleaning includes a downspout flush. Clearing the gutter without testing the spout would only be half the job.

That usually means a clog in the spout or elbow. We clear it and test the flow so water moves the way it should.
