What makes chimney cleaning & sweep in Ajax its own problem
Homes in Ajax rarely fail all at once — they fail slowly, through one heating season at a time.
Infill and renovation work in Ajax frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Many Ajax properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Across Duffin's Bay, Ajax Waterfront, Northeast Ajax, South Ajax and Central Ajax, 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 cleaning & sweep 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.
