What makes wett inspection in Cobourg its own problem
There is a rhythm to wett inspection 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.
Range hoods and basement bathroom fans routinely out-pull an older flue, so the house depressurises and the flue reverses — a Cobourg problem that looks like a chimney fault but starts elsewhere in the building.
Across Terry Fox, Burnham Street, New Amherst, Cobourg Beach and Division 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 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.
