Why gutter & eavestrough cleaning works differently in Toronto
What makes gutter & eavestrough cleaning in Toronto unusual is not the technique, it is the age spread of the housing: a single route can cover 1910 brick and 2019 factory-built venting.
Air-sealing and window upgrades have made Toronto homes far tighter than they were designed to be, and a tight house starves a natural-draft appliance of the make-up air it needs.
Post-war subdivisions across Toronto share the same construction generation, so when one street starts showing the same defect, the neighbours usually follow within a couple of seasons.
Across East York, Don Mills, Bayview Village, Yonge and St. Clair and Hoggs Hollow, the housing stock changes street by street, and the correct method changes with it. A century home with a soft-brick stack does not get the same treatment as a 2010 build with a factory-built vent — using one method on both is how systems get damaged.
If you live anywhere near the CN Tower, the practical takeaway is that a gutter & eavestrough cleaning visit should start with an assessment, not a tool. Any crew that begins work before telling you what they found is guessing on your behalf.
