Custom window costs typically range from $400 to $4,000 but most homeowners pay around $2,200 on average. From intricate arch windows to panoramic picture windows, custom windows enhance your home’s ambiance and overall look. Many top window brands offer customized traditional styles and one-of-a-kind window shapes.

This guide covers the cost, factors, and installation process for custom windows.


Cost of Custom Windows

Custom windows can cost $400 to $4,000. Prices vary by window size, design, frame materials, and customization level. Custom windows are priced 25% to 75% higher than standard ones.

For example, double-hung windows typically range from $200 to $600, while custom double-hung windows could be $350 to $1,050. A more complicated installation, such as a bow or bay window, could cost more than $1,575.


Major Cost Factors of Custom Windows

Here’s an overview of some significant factors that impact custom window cost

Factor 1: Customizations

Many manufacturers allow you to customize interior and exterior colors, grille design, hardware, and trim options. These customizations will vary based on window style and frame material. For example, vinyl windows have fewer customization choices than wood windows

Factor 2: Energy-Efficient Upgrades

Energy-efficient windows help reduce energy bills by maintaining your home’s indoor temperatures. These windows use special treatments, such as low emissivity (low-e) coatings, to retain heat in winter. According to the U.S. Department of Energy, windows with a low-e coating can reduce energy loss by 30% to 50%. Look for windows labeled with the official ENERGY STAR® certification to maximize savings.

Using windows with multiple panes of glass also increases your energy savings. Single-pane windows have no energy efficiency benefits. Upgrading to double-pane windows will improve your home’s insulation and prevent your HVAC system from working overtime, saving you money on energy bills. Many double-pane windows also include argon gas within the panes to provide added insulation. Triple-pane windows offer maximum energy savings but have the highest price tag. 

Other important considerations include the U-factor and Solar Heat
Gain Coefficient (SHGC). The U-factor measures how well the window insulates, while the SHGC notates how much of the sun’s heat passes through. You should generally look for windows with U-factors between 0.2 and 1.2. A lower SHGC is better. The U.S. Department of Energy provides more specific guidelines for different climates and regions on its website.

Factor 2: Home Age

If your home is 30 years or older or in a specific home style, such as Victorian, you may have irregular window sizes. To replace your old windows, you’ll need to have new windows made to fit the old frame. You can select a different window style, but you’ll incur additional costs to change the existing window frame. It’s best to get a cost estimate from your contractor to determine if custom windows are the best solution for your home. 

Factor 3: Labor Costs

Window installers typically charge hourly. Their rates usually range between $40 and $60 per hour, but installers will charge more for custom windows. You’ll also pay more for installations on higher floors since larger crews and special equipment are needed. Larger, complicated installations require more labor and planning. 

Factor 4: Number of Windows

Installing many custom windows requires a considerable investment, especially if you’re installing new windows in a new home. You can lower your costs by installing more affordable replacement windows in bedrooms, bathrooms, foyers, or other private areas.

Save your high-end custom windows for rooms where you’ll entertain or where elegantly designed windows are seen often. These could include your living room, foyer, or kitchen. Picture windows, for example, are an excellent addition to rooms with expansive and picturesque views. 

Factor 5: Size

Oversized windows cost more than smaller windows. Odd or unusual-shaped windows can also increase your overall budget. Window styles like bay or bow windows have a higher price tag than traditional single-hung or double-hung windows. Picture windows are always custom-size and come at a high price point. 

Factor 6: Window Frame Material

Window frames generally cost between $80 and $1,300, but these prices will increase depending on your customization.

Durable, low-maintenance vinyl windows and composite windows are the most affordable. Many window manufacturers sell fiberglass and aluminum windows, which cost a bit more but offer more durability and style options. 

Wood windows are a popular choice for window replacements but have the highest cost and require the most long-term maintenance. High-quality wood windows are aesthetically pleasing and offer the greatest customization of any window material.

Types of Custom Windows

You can customize virtually any type of window. Here are a few examples of customizable window styles.


Professional vs. DIY Custom Window Installation

Custom windows must be purchased through professional window companies. Your installer will visit your home and discuss the plans for your window project. They’ll assess your current windows and check for any cracks or damage to the frames. This will determine if a full-frame or retrofit installation is the best option. 

Retrofit installations use the existing window frame if it’s in good condition, making them less expensive. These installations are the best choice if you’re replacing your current windows with the same style.

You’ll need a full-frame replacement if your new windows are irregular or differ from your windows’ current shape. These installations require completely removing your window frame, involving more labor. Full-frame installation can increase your installation costs by 15% to 25%.

We recommend using a professional window installation company for custom window installations. These installations can be labor-intensive and too costly for a do-it-yourself (DIY) project. Depending on your selected manufacturer, you may need to hire a separate installation company. Many window companies have a network of certified installers and contractors trained to install their products. Some companies, such as Renewal by Andersen and Champion Windows, sell their own window products and provide installation.


Our Recommendation

Whether you’re looking for one-of-a-kind designs to add curb appeal or need irregular windows for a home upgrade, custom windows are the perfect accent pieces. These windows can be a pricey investment, so you must consider the number of windows you need for your design. Consider incorporating traditional styles in private areas and saving custom windows for rooms with more foot traffic and visual impact.
