Pickering conditions that change how wett inspection is done
If you mapped our Pickering service calls on a calendar, you would see the same shape every year: the problems are created in February and paid for in November.
Snow load and ice damming stress the roof-to-wall junction each winter; by spring the sealant that was doing the work has usually torn.
Range hoods and basement bathroom fans routinely out-pull an older flue, so the house depressurises and the flue reverses — a Pickering problem that looks like a chimney fault but starts elsewhere in the building.
Across Highbush, Brougham, Duffin Heights, West Shore and Greenwood, 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.
the practical takeaway is that a wett inspection 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.
