What makes chimney relining (stainless) in Caledon its own problem
The honest summary of chimney relining (stainless) in Caledon is that the work is simple and the diagnosis is not.
Salt spray and road grit carried by winter wind accelerate corrosion on exterior metal components far faster in Peel than the manufacturer's rating assumes.
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 Caledon home and nowhere else.
Across Mayfield West, Inglewood, Bolton, Cheltenham and Caledon East, 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 relining (stainless) 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.
