What makes chimney rebuild in Cobourg its own problem
There is a rhythm to chimney rebuild work in Cobourg: a quiet summer, a frantic October, and a winter of emergencies that were visible in September.
Infill and renovation work in Cobourg frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
The swing between a January cold snap and a February thaw can move a masonry assembly enough to open joints that looked sound in the fall.
Across Division Street, Burnham Street, Terry Fox, White's Road 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 rebuild 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.
