What makes smoke chamber parging in New Tecumseth its own problem
The honest summary of smoke chamber parging in New Tecumseth is that the work is simple and the diagnosis is not.
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.
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.
Across Colgan, Tecumseth Pines, Ballycroy, Beeton 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 smoke chamber parging 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.
