The local factors behind damper repair & installation in Caledon
Two houses on the same Caledon street, built the same year, can need completely different damper repair & installation work — and usually do.
Post-war subdivisions across Peel share the same construction generation, so when one street starts showing the same defect, the neighbours usually follow within a couple of seasons.
Older Caledon 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.
Across Inglewood, Cheltenham, Caledon East, Bolton and Alton, 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 damper repair & installation 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.
