The local factors behind wett inspection in Aurora
Two houses on the same Aurora street, built the same year, can need completely different wett inspection work — and usually do.
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.
Air-sealing and window upgrades have made Aurora homes far tighter than they were designed to be, and a tight house starves a natural-draft appliance of the make-up air it needs.
Across Kennedy Street West, Rural Aurora, Hills of St Andrews, Aurora Highlands and Bayview Wellington, 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.
