Window replacement prices depend on the size and style of each opening, frame material, glass package, installation method, and any damage found around the opening. National figures are planning benchmarks; the only reliable price for a particular home is a written local estimate with a defined scope.
What does window replacement cost?
Angi’s estimate, updated August 3, 2026, puts a typical full window replacement project at an average of about $7,348, with a reported range of $3,436 to $11,838. Its estimate per window ranges broadly from about $300 to $2,500, installed. These figures come from Angi’s own verified project data and may differ from other surveys and markets. See Angi’s window replacement cost data and methodology.
For comparison, This Old House reports a different result from its 2026 survey of 1,000 window customers nationwide (page updated August 11, 2026): about $517 installed per window on average, with average project spending near $7,183. The surveys use different samples and methods, so the values should not be treated as a single universal price. See This Old House’s 2026 homeowner survey.
What affects the price?
- Window style and dimensions: Standard single- or double-hung units often differ in cost from large picture, bay, bow, or custom-shaped windows.
- Frame material: Vinyl, wood, aluminum, and fiberglass have different purchase, maintenance, and installation costs. Compare the full specification and warranty, not just the material label.
- Glass and performance options: Number of panes, coatings, gas fills, sound-control features, and local energy-code requirements can change the price. Ask for the exact product rating and configuration.
- Installation method: An insert replacement may retain the existing frame when it is sound; a full-frame installation removes more of the assembly and can expose additional repair needs.
- Opening condition and access: Rot, water damage, lead-safe work requirements, upper-floor access, and trim repairs can add labor. Ask what is included and what would trigger a change order.
- Location and project size: Labor rates, permitting, availability, and the number of units affect local bids.
Estimate a whole-home project
Multiply a per-window estimate only as a rough first step. A real project quote should list each opening, window type and dimensions, product line, glass package, installation method, trim and disposal, permit responsibilities, and any allowance for damaged framing. Larger projects may receive different per-unit pricing, but do not assume every window has the same cost.
Repair or replace?
Replacing a sash, balance, weatherstripping, or hardware may address a specific problem without replacing the entire window. Replacement may make more sense when the frame is damaged, the unit no longer operates safely, or repairs cannot restore its performance. Fog between panes can indicate a failed seal, but it does not by itself tell you whether the full window must be replaced. Get a diagnosis and compare the repair scope with a replacement quote.
Will new windows lower energy bills?
Potential savings depend on the old windows, air leakage, climate, heating and cooling equipment, installation quality, and household behavior. Do not treat a projected savings figure as guaranteed. Ask the installer for the product’s verified energy ratings and check whether local utility or government incentives currently apply; eligibility and programs change.
How to compare window quotes
- Obtain itemized estimates from multiple qualified local installers.
- Compare the same openings and product specifications, including glass, frame, installation method, and finish.
- Confirm removal, disposal, trim, permits, cleanup, and warranty terms in writing.
- Ask how concealed water or frame damage will be documented and priced before work proceeds.
- Check local licensing and permit rules with the relevant authority.
Frequently asked questions
How much does it cost to replace one window?
Angi reports a broad installed range of about $300–$2,500 per window. Dimensions, style, materials, glass, labor, and repairs around the opening explain much of the variation.
Should I replace all windows at once?
Replacing several together may simplify scheduling and produce a more consistent product, but it requires a larger upfront budget. Prioritize failed or damaged units and compare project bids with phased work.
Do replacement windows increase home value?
Resale value depends on the market, product, project cost, and buyer priorities. Avoid assuming that a specific percentage of the expense will be recovered; ask local real estate professionals for market context.
