What makes chimney flashing repair in Kawartha Lakes its own problem
There is a rhythm to chimney flashing repair work in Kawartha Lakes: a quiet summer, a frantic October, and a winter of emergencies that were visible in September.
Older Kawartha Lakes stock was built when soft lime mortar and clay liners were the standard; modern high-efficiency appliances vent very differently, and the mismatch causes condensation the original builder never planned for.
Infill and renovation work in Kawartha Lakes frequently reroutes venting without re-sizing it, and undersized or over-long runs are the single most common cause of poor draft we see.
Across Sturgeon Point, Coboconk, Dunsford, Bobcaygeon and Omemee, 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 flashing repair 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.
