How Much Does Window Replacement Cost in Ontario?
Costs vary with style, size, frame material, glass package, finishing and the condition of each opening.

What an installed window price includes
A useful estimate separates the window unit, removal and disposal, installation labour, interior or exterior finishing, screens, trim, taxes and any repair to the surrounding opening. Size, style, material, glazing and access can move the total substantially.
Why quotes vary from one opening to the next
A basement slider, a large picture window and a bay projection do not carry the same handling or finishing scope. Ask whether the estimate is based on measured openings and whether repairs, capping and disposal are included.
Use a quote to compare scope
Compare the complete product specifications, number of openings, installation method, finishing and exclusions. The lowest line item is not necessarily the lowest completed-project cost.
