New Tecumseth conditions that change how chimney flashing repair is done
Homeowners in New Tecumseth tend to call us at one of two moments: the week before guests arrive, or the week after something started smelling wrong.
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 New Tecumseth home and nowhere else.
Older New Tecumseth stock was built when soft lime mortar and clay liners were the standard; modern high-efficiency appliances vent very differently, and the mismatch causes condensation the original builder never planned for.
Across Ballycroy, Colgan, Tecumseth Pines, Nicolston and Alliston, 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 flashing repair 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.
