Transom windows are an architecturally inspiring statement, and they’re not a new invention. Dating back to Gothic times, this type of window has great benefits for your home from stylistic, architectural, safety, and engineering standpoints.
What Are Transom Windows?
Transom windows are named after the crossbar or structural beam that separates the framing of the door from the framing of the window. It’s called a transom, and the transom window is that small, decorative window that sits over the top of the door or larger window.
They are popular in foyers, row houses, and townhomes, and they are typically installed for purely aesthetic purposes — not structural reasons.

Most transom windows are detailed, intricate, and ornate. They are widely loved for their ability to expand your view, open up a room, and bring in lots of extra light. While they are most commonly known for being fan-shaped, they can come in multiple types of styles including glass paneling and solid glass.
The History Behind the Trend
Although transom windows date back to 14th century Europe, they became popular in Gothic times. Historically, they were used to increase ventilation in a home. They still fulfill this purpose in some modern homes, such as open-concept bathrooms or townhouses without central air.
You will notice transom windows in many historical row houses. Like a townhouse, these homes are attached to each other by the walls on one or both sides. Because of the lack of windows in these long, narrow houses, transom windows became important to stimulate airflow throughout the structure.

Types of Transom Windows
Whether you are thinking about installing brand new windows in your home or looking to replace your existing windows, it’s helpful to know the different types of transom windows.
Hinge Types
There are three main hinge types in the world of transom windows.
Bottom hinged-transoms must be opened with a long pole. Side-hinged transoms open like doors, and top-hinged transoms generally come with lifts that can be manually operated.
Shapes
A rectangular shape is the most common style of transom window. Fanlights are also a popular style— these come in the shape of an arch.
Indoors or Outdoors
Transom windows are usually located above a front or back door. But they can also be installed over interior doors. This increases the open-concept feel of your home, while giving it a vintage flair.
Fixed or Inoperable
Not all transom windows can be opened. Fixed transoms are meant for decoration and increased light flow. They can be ideal in spaces where ventilation is not an issue. Operable transoms can be opened in a couple of different ways: the old-fashioned ones will use a window pole, while modern windows are often motorized.
Benefits of Transom Windows
Less mold and mildew.
If you have a mold problem, improving airflow is the first step in remediating it. Transom windows are the perfect stylish way to deal with moisture.
More natural light.
Natural light has so many benefits. From improving your mood, making your home look more modern, and even increasing your home’s value, the addition of natural light is a huge benefit.
Good for the environment.
A well-placed transom window allows light to flow into your home throughout the day. This will let you keep the lights off, saving on electricity bills. If you are lucky enough to have an operable transom window, you could potentially turn the A/C off and let the airflow through your window.
Safe.
Transom windows first came about because people needed a way to keep the air flowing through their homes without the risks that come with keeping a window propped open. Transoms are high enough that you don’t have as many safety concerns.
Architecturally beautiful.
Last but not least, transom windows are simply lovely to look at. Plus, you can rest at ease knowing that this trend is here to last. After all, they’ve been around for centuries.
Tips for Restoring Transom Windows
Sometimes, old transom windows have been painted over or covered with wooden panels. Uncovering them can make you feel like you’ve ripped up some 60’s shag carpet to find a beautiful hardwood floor.
With the right tools and a bit of knowledge, it’s totally possible to restore the windows to their former glory.
You’ll need to identify whether the window is made up of several individual glass panes or one large piece. For one-piece transom windows, it’s best to start by removing the trim around the window. Once it’s free, you can remove the old glass panel and replace it with a new piece of glass.
For windows that are made up of multiple glass panels, assess the entire window to decide whether all the panels need to be replaced. If some of them are in good condition, you can remove individual panels by prying away the glazing around that panel. Replace the glass, then reapply the glazing compound to fix it in place.
How Much Do Transom Windows Cost?
The cost to replace transom windows can range anywhere from less than $100 to over $575. The cost depends on a variety of factors including the style, material type, whether you need weatherproofing, and whether the windows are fixed or inoperable. Keep in mind that transom windows have real potential to increase the value of your home.
Improve the Value of Your Home with Transom Windows
Transom windows are more than just a beautiful architectural statement. They also perform a vital function in the safety and comfort of a building. Due to their height and placement, transom windows, when opened, can provide a comfortable cross-breeze.
Before the days of air conditioning, these windows provided important ventilation in a building. Without them, homes — especially long townhomes with few windows on the sides — would trap air and become stuffy. Transom windows at the front and back of the home created ventilation.
Today, transom windows are growing in popularity. Modern homes are built with an emphasis on high ceilings and natural light. Operable transom windows have great potential to improve ventilation, help you to cut down on energy costs, increase the flow of light to a room, and improve your home’s value.
