Aurora conditions that change how chimney cleaning & sweep is done
If you mapped our Aurora service calls on a calendar, you would see the same shape every year: the problems are created in February and paid for in November.
Range hoods and basement bathroom fans routinely out-pull an older flue, so the house depressurises and the flue reverses — a Aurora problem that looks like a chimney fault but starts elsewhere in the building.
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 Aurora Grove, Kennedy Street West, Aurora Highlands, Bayview Northeast and Hills of St Andrews, 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.
