What makes chimney cleaning & sweep in St. Catharines its own problem
The honest summary of chimney cleaning & sweep in St. Catharines is that the work is simple and the diagnosis is not.
Older St. Catharines 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 St. Catharines home and nowhere else.
Across Burleigh Hill, Glenridge, Downtown St. Catharines, Bunting and Port Dalhousie, 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 Welland Canal, the practical takeaway is that a chimney cleaning & sweep 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.
