Average Cost To Replace A Window

Replacing windows can make your home feel cozier, look better, save energy, and increase your property’s worth. But figuring out the cost can be confusing. However, the average cost to replace a window ranges between $200 and $2,500, depending on many key factors. The national average cost to replace a window is around $850. However, the cost to replace 25 windows is typically $17,000 to $20,000 or more.
1. Window Replacement Cost By Number Of Windows
The cost to replace windows depends greatly on the number of windows to be replaced. The greater this number, the higher the price will be.
2. Window Replacement Cost By Window Type
You may choose any window type as per your requirements. For example, consider adding slider windows during bathroom renovations and bay windows during kitchen renovations. However, the timeline for kitchen renovations may take from 2 weeks to 3 months. Installing a bay window is costly compared to a single-hung window.
3. Window Replacement Cost By Window Size
Large-sized windows are simply costly compared to a smaller size. For example, a small window size of 24″x36″ averages $760, while a large window size of 60″x72″ may cost you $1,663.
4. Window Replacement Cost By Frame Material
Window replacement cost is greatly impacted by its frame material. Some materials, like composite, fiberglass, and wood, are much costly compared to aluminum and vinyl.
5. Window Replacement Cost By Energy Efficiency Rating
Energy efficiency matters a lot when you’re living in harsh weather conditions. These windows have a U-factor describing their energy efficiency rating. Windows with a U-factor less than 0.20 are best for extreme weather conditions, but may cost you more compared to windows with a U-factor above 0.20 or 0.30. ENERGY STAR® windows can also be chosen.

6. Window Replacement Cost By Glass Type
Glass type impacts the cost to replace the windows, too. You may choose single, double, or triple pane with argon gas, low-E coating, or tempered glass as per your requirements. A triple glass pane filled with argon gas is much more costly compared to a single pane of glass. Consider installing tempered glass windows during garage renovations.
