The local factors behind creosote removal in Aurora
The difference between a $200 service call and a $6,000 rebuild in Aurora is usually about eighteen months of ignoring a small symptom.
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 Aurora home and nowhere else.
Salt spray and road grit carried by winter wind accelerate corrosion on exterior metal components far faster in York than the manufacturer's rating assumes.
Across Hills of St Andrews, Aurora Highlands, Bayview Northeast, Aurora Grove and Rural Aurora, 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 creosote removal 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.
