Oshawa conditions that change how downspout extensions & drainage is done
Homeowners in Oshawa tend to call us at one of two moments: the week before guests arrive, or the week after something started smelling wrong.
Many Oshawa properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Wind loading off Lake Ontario pushes driving rain against the south and west faces of a house, which is why water entry so often shows up on one side of a Oshawa home and nowhere else.
Across Lakeview Oshawa, Raglan, Vanier, Windfields and Columbus, 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.
