Exterior Door Sidelights: An Overview
Sidelights are the extra touch that will reinvent your front door and improve the façade of your home, optimizing curb appeal.
Sidelights are the vertical windows installed on one or both sides of an exterior entry door.
Door sidelites are usually built into the same frame assembly as the door, but you can also buy them separately and have them installed individually. They come with different glass options: clear, frosted, stained, or tinted. Hence, front entry door sidelights have both a functional and a decorative purpose.
Most traditional sidelights do not open and are accompanied by transom windows – the horizontal windows situated above a door. However, you can find modern doors with sidelights that open and are fully functional.
While you can find interior doors with sidelights, the most common models are designed for outdoor doors. You can choose from ½, ¾, full-length, or craftsman light sidelights. Sidelights for exterior doors usually have a width of 36 inches and are built in 2-inch increments. Standard sidelights are 12 or 14 inches.
Remember to always add another 3 inches for the trim for an accurate opening measurement. A front door typically measures 80 inches plus 1-2 inches for the jamb. Choose a sidelight that has the same height as the front door, jamb included.
Can you buy replacement front door sidelights separately?
Yes, you can usually buy replacement front door sidelights separately, as many manufacturers offer them as standalone units. However, availability and fit can vary, so it’s important to match the size, style, and frame type to your existing door system.
Reasons to Install Entry Doors with Sidelights
There are numerous benefits to sidelights. Sidelights can be a budget-friendly way to improve your home. Front doors are no longer just the entryway to your home. Forget about the plain, old doors and make a statement with doorways with sidelights. They can add a touch of color to your home’s façade and complement the architectural choices you’ve made.
Exterior Front Doors with Sidelights Are Energy-Efficient
One of the most important benefits of sidelights is that they contribute to the energy efficiency of your home. Modern sidelights are designed and built with insulation channels and tempered glass that will allow you to enjoy the advantages of sidelights without compromising your comfort and energy consumption.
Front Door with Sidelights Add Extra Natural Light
The one benefit that convinces most homeowners to keep, replace, or add sidelights to their front door is the extra natural light that comes with them. Besides brightening up your entryway and inviting additional warmth and beauty to the interior, sidelights also allow you to see who is knocking at your door. Moreover, it is a great way for pets and kids to have access to the exterior world without exposing themselves to any danger.
Sidelights for Front Doors Can Allow Extra Fresh Air
If you decide to replace your old sidelights or add new sidelights to the front entryway, you should consider sidelights that open for some extra fresh air. These sidelights can be fully opened when you want to invite fresh air into your home, but they are narrow enough to keep potential intruders uninterested.
One common concern with sidelights is that they may allow strangers to peek inside your home. If your front door is exposed to the sidewalk or passers-by, you can always consider adding frosted or stained-glass sidelights instead of clear glass options. This way, you can still enjoy all the benefits of sidelights without worrying about unwanted attention. The addition of charming curtains gives you another option if decorative glass isn’t your thing.

How to choose front door sidelights?
First of all, you need to decide if you want to buy a front door assembly that already includes the sidelights in the frame, or if you are going to add sidelights to the existing door. Buying a front door with fitted sidelights makes for the easiest way to enjoy the benefits of sidelights. A door with one sidelight costs around $1,600, while a door fitted with two sidelights can run for $2,500, if not more, depending on the material of the door and the glass style.
The cost of front door sidelights depends on your preferences. You can choose from various models and sizes, with or without panels or glazing bars. Moreover, sidelights come in various materials and colors and can be fitted with different types of glass.

Many homeowners find it difficult to decide if the door, sidelights, and trim should be in the same color or have different colors. The answer depends on the color and architecture of your house, although the common choice seems to be a single color.
Nevertheless, current trends dare you to be creative when it comes to doors with sidelights. Contrasting colors can add value to the overall aesthetics of the house. Now, if your door is painted in a joyful color, like pink, red, or orange, it is best to keep the sidelights in the color of the trim.
How to replace front door sidelights?
Replacing front door sidelights generally involves removing the old trim, carefully taking out the existing sidelight unit, and installing a new, properly sized unit before resealing and reinstalling the trim.

In case you notice that the glass is fogging up, or if the frame or the sash around the sidelight is rotten or looks old, you should not postpone repairing your sidelights. This contributes to your comfort and privacy and makes your home more energy efficient. If the glass is not broken, you can replace only the rotten brickmould or other wood components.
