Why chimney leak repair works differently in Niagara-on-the-Lake
Niagara-on-the-Lake sits in a freeze-thaw belt, and freeze-thaw is what quietly takes apart masonry, flashing and venting.
The swing between a January cold snap and a February thaw can move a masonry assembly enough to open joints that looked sound in the fall.
Infill and renovation work in Niagara-on-the-Lake frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Across Glendale, Line 2, St. Davids, Line 3 and Line 4, 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 leak 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.
