Why dryer vent bird guard installation works differently in Aurora
Aurora sits in a freeze-thaw belt, and freeze-thaw is what quietly takes apart masonry, flashing and venting.
Infill and renovation work in Aurora frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Wind loading off Lake Ontario pushes driving rain against the south and west faces of a house, which is why water entry so often shows up on one side of a Aurora home and nowhere else.
Across Bayview Southeast, Aurora Village, Rural Aurora, Bayview Wellington 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 dryer vent bird guard installation 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.
