Richmond Hill conditions that change how chimney animal removal is done
If you mapped our Richmond Hill service calls on a calendar, you would see the same shape every year: the problems are created in February and paid for in November.
Range hoods and basement bathroom fans routinely out-pull an older flue, so the house depressurises and the flue reverses — a Richmond Hill problem that looks like a chimney fault but starts elsewhere in the building.
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.
Across Oak Ridges, Elgin Mills, Yonge Corridor, Bayview Hill and Langstaff, 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 animal 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.
