New windows typically cost between $600 and $1,500 per window installed, with the wide range reflecting differences in frame material, glass package, window size, installation type, and regional labor costs. A full-home replacement of 10–15 windows on an average your region home typically runs $8,000–$20,000.
“The price range for window replacement is genuinely wide — and it’s wide because the product range is wide. A $700 installed window and a $1,400 installed window can look identical from the street. The difference is in the frame quality, the glass package, the Low-E coating, the gas fill, and the spacer type. Those differences determine how the window performs for the next 20 years.”
— Marcus Webb, building science consultant and ENERGY STAR program participant with 12 years of experience advising homeowners on window and insulation upgrades in the local area

What Drives Window Costs Up
Frame material. Fibreglass frames cost 15–25% more than comparable vinyl but offer superior longevity and performance.
Triple-pane glass. Adds approximately $150–$300 per window over double-pane, with meaningful performance improvements in cold climates.
Full-frame vs. insert replacement. Full-frame replacement costs $150–$400 more per window than an insert replacement, but is the correct approach when existing frames show damage.
Window size and complexity. Bay windows, arched windows, and custom shapes command significant premiums.
Installation complexity. Second-storey windows, windows requiring scaffolding, and large picture windows all increase labor cost.
Number of windows. Per-window costs decrease slightly with larger orders as setup and teardown costs are amortized.
What Should Be Included in the Price
A complete window quote should include: the window unit with specified frame material and glass package, removal and disposal of the old windows, flashing and air sealing, exterior trim and caulking, interior trim reinstallation, and cleanup. If any of these are absent, ask why.

Available Rebates
ENERGY STAR certified windows meeting zone-appropriate performance thresholds may qualify for federal or regional rebate programs. Check a national energy-efficiency rebate program and your regional energy efficiency programs for current rebate amounts. Some utilities also offer incentives.
Getting Multiple Quotes
For a full-home window replacement, three quotes is the right minimum. Make sure each contractor is quoting the same product specifications — frame material, glass package, U-factor — so you’re making a true comparison.
