The local factors behind downspout extensions & drainage in New Tecumseth
Ask any technician who works New Tecumseth routes and they will tell you the same thing: the callbacks cluster in a handful of predictable places.
Range hoods and basement bathroom fans routinely out-pull an older flue, so the house depressurises and the flue reverses — a New Tecumseth problem that looks like a chimney fault but starts elsewhere in the building.
Air-sealing and window upgrades have made New Tecumseth 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 Ballycroy, Tottenham, Rosemont, Nicolston and Loretto, 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 downspout extensions & drainage 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.
