Cambridge conditions that change how chimney cap installation is done
If you mapped our Cambridge service calls on a calendar, you would see the same shape every year: the problems are created in February and paid for in November.
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 Cambridge home and nowhere else.
Infill and renovation work in Cambridge frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Across Bridgeport, Beaverdale, Fiddlesticks, Alison and Central Preston, 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.
If you live anywhere near the Grand River, the practical takeaway is that a chimney cap 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.
