For a typical Georgina home (2,000–2,400 sq ft roof), install 5" K-style aluminum eavestrough at ¼" per 10 ft of pitch, with a 3"×4" downspout every 35 linear feet. Discharge 6 ft from the foundation. Total install runs $2,400–$4,800 with a 25-year workmanship warranty. Same-week booking across Georgina.
Gutter size is a drainage math problem, not a style choice. Multiply roof drainage area by the local 1-hour rainfall intensity (Toronto: ~40 mm/h). A 5" K-style aluminum gutter handles about 5,500 sq ft of roof; a 6" handles ~7,960. Any long steep roof plane over 1,000 sq ft or any valley dumping into a gutter is an automatic step-up to 6".
Downspouts: 2"×3" moves ~600 sq ft; 3"×4" moves ~1,200 sq ft. In Georgina we default to 3"×4" — the cost delta is under $80 per drop and it eliminates 90% of overflow callbacks.
Georgina isn't uniform — tree cover, roof age, and lot slope drive different gutter specs across neighborhoods. Below: what we typically install in each.
No. Eavestrough replacement is maintenance under the Ontario Building Code — no permit required. New downspout discharge locations may need to comply with local stormwater bylaws.
Seamless every time on residential. We roll-form on-site to the exact wall length, cutting leak points by ~80%.
