Clarington conditions that change how chimney relining (stainless) is done
If you mapped our Clarington service calls on a calendar, you would see the same shape every year: the problems are created in February and paid for in November.
Many Clarington properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Post-war subdivisions across Durham share the same construction generation, so when one street starts showing the same defect, the neighbours usually follow within a couple of seasons.
Across Bowmanville, Enniskillen, Tyrone, Courtice and Hampton, 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.
