Understand window pricing factors, compare costs, and learn how to get the best value on replacement windows and doors.
Window prices vary based on several key factors: the type of window (double-hung, casement, bay, etc.), the glass package (double-pane vs. triple-pane, Low-E coatings, gas fills), frame material, custom sizing, and hardware options like grilles and locks. Standard-sized double-hung windows typically range from $300 to $800 per unit for supply-only, while specialty windows like bay and bow configurations can range from $1,200 to $3,500 depending on size and features. Installation costs add $150 to $400 per window for replacement projects and vary for new construction based on opening preparation.
The factory-direct model used by Panes eliminates the middleman markups that inflate prices at big-box retailers and traditional window dealers. When you buy from a retailer, your price includes the manufacturer's margin, the distributor's margin, and the retailer's margin — each adding 20–40% to the cost. By manufacturing and selling directly, Panes passes those savings to homeowners, typically resulting in 20–30% lower prices for comparable or better-quality products. You also get the benefit of working directly with the people who build your windows, ensuring better communication and quality control.
When comparing window quotes, make sure you are comparing apples to apples. Look at the full specifications including U-factor, SHGC, glass type, frame construction, hardware quality, and warranty terms. A lower-priced window with poor energy ratings could cost you more in heating and cooling bills over its lifetime than a premium window. Our Smart Buyer's Pricing Guide helps you understand every line item in a window quote, avoid common pricing traps, and calculate the true long-term value of your investment.
