How Much Does It Cost to Replace Windows in 2026?
The average cost to replace a window is $300 to $900 per window installed. Here is what drives that range, the best window types for the money, and when to replace vs repair.
Window replacement is one of those projects where the upfront cost feels high but the long term benefits in energy savings, comfort, and home value make it worthwhile. The average cost to replace a window runs $300 to $900 per window installed, with most homeowners paying $450 to $650 per window for a mid-range double-hung replacement.
Average Cost to Replace Windows in 2026
| Window Type | Per Window Installed |
|---|---|
| Double-hung, standard size | $300 to $700 |
| Casement window | $400 to $900 |
| Bay or bow window | $1,200 to $3,500 |

What You Are Paying For
The window unit itself typically costs $150 to $400 for a standard double-hung. Labor runs $100 to $300 per window. A full house replacement of 10 to 15 windows typically runs $5,000 to $12,000 installed, and most window companies offer a per-project discount when replacing multiple windows at once.
Before You Replace: Two Affordable Fixes to Try First
If your windows are drafty but otherwise in good condition, two inexpensive solutions can dramatically improve energy performance without full replacement.
Window door weatherstrip seal adhesive foam tape fills gaps around window frames where cold air infiltrates. It costs $5 to $15 per roll, takes minutes to apply, and immediately reduces drafts and heating bills. Replace it every 2 to 3 years as it compresses over time.
For single-pane windows in older homes, a window insulation film kit shrinks tight with a hair dryer to create an invisible air barrier over the entire window surface. It adds a meaningful R-value to single-pane glass, reduces condensation, and costs under $30 for multiple windows. A practical winter fix while you budget for full replacement.
Single Pane vs Double Pane vs Triple Pane
Single pane windows have almost no insulating value and should be replaced in any climate. Replacement will pay for itself in energy savings within 5 to 10 years.
Double pane windows with low-E coating and argon gas fill are the standard for most homes and offer excellent energy performance at a reasonable price.
Triple pane windows cost 20 to 30% more than double pane and make sense in very cold climates. For most of the country, double pane low-E is the right choice.
Tax Credits and Rebates
The federal Energy Efficient Home Improvement Credit covers 30% of the cost of qualifying energy efficient windows up to $600 per year. Check with your window supplier whether the products you are considering qualify before purchasing.
Bottom Line
Budget $450 to $650 per window for a quality double-hung replacement professionally installed. A full home window replacement of 12 windows runs approximately $6,000 to $9,000. Get two to three quotes, ask about energy tax credits, and try weatherstripping and film first if budget is a concern.
