Matching Window Casings With Your Interior Design

Trim boards or, simply trims, cover a wide variety of interior design elements. In window replacement, these trims cover the intersections and connections between the window and the wall, helping to make it look finished and beautiful. Trims for windows are more commonly referred to as casings. These are the ones that create an additional “frame” around the window and door and hide the areas where the jamb meets adjacent walls.

Window Casings

Choosing a window casing might sound like a simple decision but there are actually a lot of factors to consider to make your new replacement windows look consistent with the rest of your interiors in terms of design. Here are a few tips from our window experts at Renewal by Andersen® of Long Island on how to choose the right casing for your windows.

Wisely and Consistently

Take your time to search for a casing that will complement your windows well. Casings must be consistent with other trims present in the room. However, be cautious when using trims because too many of them can easily overpower other design elements in the room. The key is to balance the effects of casing in your design with the rest of your interiors. An experienced window design consultant can help you strike this balance.


The size of your trims should also be scaled accordingly to the size of both the window and the rooms. Large trims can make replacement windows appear smaller than they already are, which, in turn, can make a room look more cramped than it actually is. Conversely, small trims might not have the same impact when placed in a sufficiently large room. Talk to your window replacement expert about how to size trims in proportion to the rooms in your home.

Special Cases

Sometimes, it may be necessary to use trims on specialty windows or to match other trims in older homes. These designs might no longer be available so you will need to use a little creativity when matching designs.

"I was very impressed with Renewal by Andersen. They showed up in time and we received several follow up phone calls as the installation was being done as well as the sales representative stopping by to check in on the installation. The delivery/ installer was very professional. I would highly recommend Renewal By Andersen."
