What Is a Transom Window?
Transom windows are horizontal windows positioned above doors or windows. They serve aesthetic and practical purposes, bringing added light into a space while providing architectural detail. Transom windows can be fixed or operable.
Historical Significance
The use of transom windows dates back to Europe in the 14th century. They were first designed to provide additional ventilation and natural light while maintaining privacy because of their high placement.
Early versions often featured wood shutters or animal hide closures for protection against the elements. In interior applications, transom windows helped improve air circulation between rooms, which was important before the advent of modern HVAC systems.
Modern Applications
Today, people primarily use transom windows as decorative elements that enhance their home’s overall design. You’ll see them in homes above exterior doors, where they can create a grand entrance and flood entryways with natural light. Interior transom windows are also popular—they open up spaces between rooms without sacrificing privacy or structural integrity.
Benefits and Drawbacks of Transom Windows
Like any home improvement feature, transom windows have advantages and drawbacks. Understanding these pros and cons can help homeowners decide if the windows are right for their living space.
Transom Window Styles and Designs
Transom windows come in a variety of styles to suit different architectural preferences and functional needs. Some popular options include:
- Arched transom windows: These elegant windows feature a curved top, often spanning the width of a door and any accompanying sidelights.
- Rectangular transom windows: A classic choice that offers a clean, simple look suitable for many home styles.
- Fanlight transoms: These semi-circular windows are a hallmark of Georgian and Federal-style architecture.
- Operable transom windows: You can open them for more ventilation, similar to awning or casement windows.
Homeowners can also choose from various glass options, including:
- Clear glass for maximum light transmission
- Frosted or textured glass for privacy
- Stained glass for a decorative touch
- Energy-efficient double-pane glass to improve insulation
- Specialty glass: Some transoms feature leaded glass or beveled edges for an added touch of elegance and historical accuracy.
Transom Window Installation
Installing transom windows requires careful planning and, in most cases, professional expertise. The process can vary depending on whether the window is being added to an existing structure or incorporated into new construction.
Structural Considerations
Before installation, you need to assess the structural implications of adding a transom window. Key factors include load-bearing capacity, ceiling height, and existing utilities.
If the wall is load-bearing, you need to make structural modifications to support the new opening. Transom windows typically require higher than standard ceilings to maintain proper proportions. You may also need to relocate electrical wiring, plumbing, or HVAC components if they travel through your wall.
Installation Process
While specific steps may vary, the general process for installing a transom window includes:
- Creating the opening: This involves cutting into the wall and framing the new space.
- Installing support: Adding a header beam to bear the load above the window.
- Weatherproofing: Applying proper flashing and sealants to prevent water infiltration.
- Inserting the window: Carefully placing and securing the transom window in the prepared opening.
- Finishing: Completing interior and exterior trim work to integrate the window seamlessly.
Due to the complexity of this process, we recommend homeowners hire experienced professionals for transom window installation. Experts can provide a proper fit, function, and compliance with local building codes.
Transom Window Costs
The cost of adding transom windows to a home can vary widely based on several factors. These include the size and style of the window, the complexity of installation, and whether it’s part of new construction or a renovation project.
Material Costs
Basic transom windows can start at around $250 per window for simple, fixed models with vinyl or low-grade wood frames. High-end options, such as custom-designed wood frames or operable windows with advanced glazing, can cost upwards of $750 per window. Specialty glass, such as stained or leaded glass variations, also may contribute to higher cost brackets.
Labor Costs
Professional installation costs typically range from $150 to $250 per hour, with total labor costs averaging between $450 and $1,500 for a standard installation. More complex projects, especially those requiring significant structural modifications, can increase the costs substantially.
Additional Considerations
Homeowners should also factor in potential additional expenses such as permits and inspections, structural reinforcement (if needed), interior and exterior finishing work, and energy-efficient upgrades (like low-E coatings or argon gas filling).
Purchasing windows in bulk for multiple areas of your home usually results in some cost savings on both materials and labor.
Choosing the Right Transom Window for Your Home
Selecting the appropriate transom window involves considering both aesthetic and practical factors. Here are some key points to keep in mind:
Architectural Compatibility
The style of the transom window should complement the existing architecture of the home. For example, arched transoms often suit traditional or Victorian-style homes, while clean-lined rectangular transoms may be more appropriate for modern designs.
Functionality
Decide whether a fixed or operable transom window best suits the needs of the space. Operable windows provide additional ventilation but require more maintenance over time.
Energy Efficiency
In regions with extreme temperatures, choosing energy-efficient options like double-paned glass or low-E coatings can help maintain comfortable indoor temperatures and reduce your energy costs.
Privacy Needs
For areas where privacy is a concern, consider frosted, textured, or stained glass options that allow light to enter while obscuring the view.
Budgetary Constraints
Evaluate your overall budget for the project, including installation and additional features. Get multiple quotes from contractors and compare the quality and price of different window options.
Final Thoughts About Transom Windows
Transom windows offer a unique blend of form and function, adding character to homes while improving natural lighting and ventilation. While they require careful consideration in terms of design, installation, and maintenance, the aesthetic and practical benefits can make them a worthwhile investment for many homeowners.
As with any significant home improvement project, weigh the costs against the potential benefits and work with qualified professionals to ensure proper installation.

Frequently Asked Questions
Are transom windows outdated?
While they’re definitely an older architectural feature, transom windows aren’t outdated by modern standards. They’re still a popular window option.
Why is it called a transom window?
Transom is an architectural term for crossbeams that lie over the tops of doorways. Transom windows sit on top of these beams, hence the name.
Do transom windows open?
Some transom windows open via a crank, lever, or remote.
Can you put shutters on a transom window?
You can put shutters or blinds on your transom windows, but most people who pick these windows for their front door avoid using any covering. The excess lighting can make any entryway feel larger and more open, which is why most people install exterior transom windows in the first place.
Why do old houses have windows above doors?
Older homes had transom lights—or fanlights—to let in more light and fresh air. Though this architectural style fell a bit out of favor in the 60s, 70s, and 80s, it has come back into style in recent years.
