Nearly every urgent dryer vent risk call we take in Cobourg began as something a homeowner noticed months earlier and reasonably decided to watch.
Salt spray and road grit carried by winter wind accelerate corrosion on exterior metal components far faster in Durham than the manufacturer's rating assumes.
Snow load and ice damming stress the roof-to-wall junction each winter; by spring the sealant that was doing the work has usually torn.
Across Burnham Street, Elgin Park, Cobourg Beach, Division Street and New Amherst, 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 dryer vent risk 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.
