Peterborough conditions that change how chimney waterproofing is done
If you mapped our Peterborough 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 Peterborough properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
The swing between a January cold snap and a February thaw can move a masonry assembly enough to open joints that looked sound in the fall.
Across Northcrest, Downtown Peterborough, Highland Heights, Talwood and Otonabee, 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.
If you live anywhere near the Peterborough Lift Lock, the practical takeaway is that a chimney waterproofing 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.
