Downspout cleaning & unclogging in Mississauga

Two Mississauga specifics send water where it should not go. First, guards: thousands of homes in Erin Mills, Meadowvale and Streetsville have screens that keep leaves out of the trough but do nothing for the downspout — seeds and shingle grit still wash down and build a plug at the elbow. A guarded gutter that overflows usually has a downspout problem, not a gutter problem. Second, the townhouse blocks: shared rooflines drain long runs into a single spout, so one blocked elbow can back water up across two or three units' worth of gutter.

Every cleaning we do ends with a downspout flush and an end-to-end flow test — included, not an add-on, because water that cannot leave the gutter is the whole problem. We clear blockages from the top or the elbow and check that discharge lands away from the foundation, not against it. For 2026, a two-storey townhouse cleaning with the full flush is $349, and taking guards off and putting them back adds $40.
