How Much Does Window Glass Replacement Cost in the GTA?

The cost of window glass replacement in the Greater Toronto Area depends on the size of the pane, the type of glass, and whether you are replacing a single pane or an entire insulated glass unit (IGU). In most cases, replacing only the glass—not the whole window—saves 60 to 80 percent compared to a full window replacement.

What Affects the Cost?

Glass type (single-pane, double-pane IGU, tempered, laminated, Low-E), size and thickness, and accessibility (e.g. upper floors, difficult access) all affect the final price. Quantity matters too: replacing several windows at once is often more cost-effective per window than a single pane.

Typical Ranges

Single-pane replacement is often the least expensive. IGU (double-pane unit) replacement costs more but is still far less than a full window. Tempered or safety glass and upgrades like Low-E or argon add to the cost. OhMyGlass provides a free, written quote before any work begins so you know exactly what to expect.
