The local factors behind chimney inspection in Cobourg
Two houses on the same Cobourg street, built the same year, can need completely different chimney inspection work — and usually do.
Post-war subdivisions across Durham share the same construction generation, so when one street starts showing the same defect, the neighbours usually follow within a couple of seasons.
Many Cobourg properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Across Downtown Cobourg, Division Street, Terry Fox, Elgin Park and Legion Village, 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 chimney 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.
