Common Questions.

How much does window replacement cost in Toronto?
Window replacement costs in Toronto typically range from $600 to $1,800 per unit, depending on frame material and glazing (double vs. triple pane). Optima Windows offers direct-from-manufacturer pricing and 2026 Enbridge rebates to offset initial investments, often saving homeowners 15–25% on annual bills.
What is the best window type for Canadian winters?
Triple pane windows with Low-E coating and argon gas fill are the optimal choice. They provide superior insulation with U-values as low as 0.20. Energy Star Most Efficient certified windows, like those engineered by Optima, act as a thermal barrier against -30°C temperatures.
How long does professional installation take?
A standard installation takes 45-60 minutes per window. A full home retrofit (10-15 windows) is generally completed in 1 to 2 days by our certified in-house engineering team, ensuring a clean site and perfect weather sealing.
