What makes chimney repointing & brick repair in Niagara-on-the-Lake its own problem
Homes in Niagara-on-the-Lake rarely fail all at once — they fail slowly, through one heating season at a time.
Older Niagara-on-the-Lake 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.
Air-sealing and window upgrades have made Niagara-on-the-Lake 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 St. Davids, Line 4, Line 1, Randwood and Garrison Village, 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 Shaw Festival, the practical takeaway is that a chimney repointing & brick 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.
