Cobourg conditions that change how chimney cleaning & sweep is done
Most Cobourg homeowners book chimney cleaning & sweep for one reason and discover a second problem on the same visit.
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.
Many Cobourg properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Across Burnham Street, Downtown Cobourg, Terry Fox, Cobourg Beach and Ontario Street, 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 cleaning & sweep 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.
