Window Replacement Cost in Kelowna (2026)

In Kelowna, a permit is generally not required if you are replacing windows with the same size units. However, if you are enlarging the opening or making structural changes, a City of Kelowna building permit is required, with fees typically starting at a minimum of $150 based on project valuation.

The CleanBC Better Homes program offers rebates of $100 per window, up to a maximum of $2,000 per household. Income-qualified residents may be eligible for enhanced rebates covering up to 95% of costs, capped at $950 per window. Note that some program components are scheduled for review or discontinuation in July 2026.

Triple-pane windows, which are increasingly the standard for Kelowna's climate, typically cost 15% to 30% more than double-pane units. For an average $14,500 project, this adds approximately $2,175 to $4,350 to the total cost but can reduce annual energy bills by up to $800.

For a standard detached home with 10 to 12 windows, Kelowna homeowners should budget between $12,000 and $17,000 for a full-service installation. Large-scale projects or those involving premium materials like fiberglass or wood can exceed $27,000.
