Window Replacement Cost Factors
The cost of a window replacement project in St. Louis depends on the number and style of your windows, their material, and glass type. Read more about each cost factor below.
Number of Windows
As with most home improvement projects, the larger the scope, the higher the price. Regarding window replacement, your cost will depend on the number of windows in your home. The average house size in St. Louis is 1,568 square feet, and most homes of this size have at least eight windows. The per-window cost in this area is $300 to $1,500, so you’ll likely pay between $2,400 and $12,000.
Frame Material
Vinyl windows are popular in St. Louis because of their affordability, durability, and low maintenance requirements. Vinyl can resemble wood without the additional work; while true wood window frames are hard to beat for their aesthetics, they require routine maintenance to protect them from the St. Louis humidity.
| Frame Material | Average Cost per Window |
|---|---|
| Aluminum | $75–$400 |
| Composite | $300–$1,200 |
| Fiberglass | $500–$1,500 |
| Vinyl | $100–$900 |
| Wood | $150–$1,300 |
Glass Type
In St. Louis, the summers are hot and humid, and the winters are cold. Therefore, you need window glass that will keep your home’s interior temperature comfortable, no matter the weather outside. Double-pane glass is an excellent insulator and popular among homeowners for its relative affordability. Triple-pane glass offers additional insulation but comes at a premium.
Low-emissivity, or low-E glass, can keep your home well insulated while also offering UV protection. Finally, tempered glass may be worth considering as it can hold up better to impacts, such as tornadoes or other storm debris.
| Glass Type | Average Cost per Window |
|---|---|
| Tempered | $200–$500 |
| Double-pane | $200–$2,000 |
| Triple-pane | $1,000–$4,000 |
| Low-E | $300–$1,100 |
Window Style
St. Louis boasts a wide range of architectural styles, from French Colonial and Italianate to Craftsman and Tudor Revival, with various window styles to complement each home’s unique design. Simple and practical windows, like single-hung or double-hung, offer form and function and suit a variety of St. Louis homes. More ornate homes may have different window styles, like arched or bay windows.
| Window Style | Average Cost per Window |
|---|---|
| Arched | $350–$1,000 |
| Bay | $900–$7,100 |
| Casement | $150–$1,000 |
| Double-hung | $150–$650 |
| Picture | $65–$700 |
| Single-hung | $100–$400 |

Labor
Labor can account for a significant portion of your total window replacement costs. The cost of living in St. Louis is about 6% lower than the national average. Therefore, your labor costs may be slightly less than the national average of $100 to $300 per window. More complex installations may take longer or require extra work, costing $600 or more per window in labor alone.
Permits
Whether you need a permit for window replacement in St. Louis depends on the project's scope. A permit isn't required if you’re replacing existing windows and won’t be making any modifications to the opening itself. However, widening the opening to install a larger window or creating a new opening to install an additional window requires a permit. Your window replacement pro will be able to handle any permitting requirements on your behalf.
Taxes
St. Louis has a combined sales tax rate of 9.68%. When you request a quote from a window replacement company, they will include sales tax in the total estimate. However, if you plan to buy new windows and either install them yourself or hire a pro for installation, you’ll need to remember to include taxes in your budget.
Tipping
There is no expectation for tipping when it comes to window replacement. However, you may choose to give your contractor a tip of 10% to 20% if they exceed your expectations. Alternatively, you can leave them an online review.
Does Window Replacement Increase Home Value?
Replacing windows can increase the value of your St. Louis home. According to the Journal of Light Construction’s 2024 Cost vs. Value report, vinyl window replacement has a 54.4% return on investment (ROI) in St. Louis, while wood window replacement has a 51.5% ROI.
If you spend $6,500 on your window replacement project, that means you will likely recoup between $3,350 and $3,550 when you sell your home.
