In Ontario, window replacement costs in 2025 are expected to range from $300 to over $3,000 per window, depending on factors such as type, material, size, and installation difficulty. Replacing all the windows in a house generally falls between $10,000 and $30,000 or more, with the final price influenced by the number of windows and any custom features.
Therefore, knowing the total cost of installing new windows helps you budget more effectively and avoid unexpected expenses.
Key elements that contribute to the overall cost of installing new windows:
✓ Window Type and Material: the type of window (e.g., bay and bow windows, double-hung, single or double slider) and material (vinyl, wood, fiberglass) can significantly impact cost. Vinyl is generally more costeffective, whereas wood and fiberglass options are often associated with higher costs.
✓ Customization Options: custom shapes, colors, and decorative glass features can add to your window cost.
✓ Energy Efficiency and Glass Options: windows with energy-efficient features like Low-E coatings or triple-pane glass are more expensive but offer longterm savings on energy bills.
✓ Labor and Installation Costs: labor costs vary based on expertise and location. Hiring professional installers ensures quality but comes at an additional expense, often ranging from $100 to $300 per window. The complexity of the job could impact on labor costs (e.g. multi-story homes, custom frames, or structural repairs).
Additional expenses that may not be immediately apparent but can contribute to the overall total cost include:
✓ Disposal of Old Windows: many installation services charge extra for removing and disposing of old windows. This fee can range from $50 to $100 per window.
✓ Repairs and Preparation Work: Preparation of the window opening or remediaƟon of any structural concerns may result in supplementary expenses.
