What makes downspout extensions & drainage in Ajax its own problem
Homes in Ajax rarely fail all at once — they fail slowly, through one heating season at a time.
Older Ajax 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.
Many Ajax properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Across Audley, Riverside Ajax, Northeast Ajax, Pickering Village and South Ajax, 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 downspout extensions & drainage 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.
