How to Match Window Trim With Your Interior

Trim or molding refers to any decorative element that covers joints of various surfaces and materials. An example of it would be the casing that surrounds your windows and doors, creating a frame that hides the gap between the jamb and the adjacent wall. The outer edge of this type of trim is usually flat to give way for the addition of horizontal trim.

The window trim comes in various designs and configurations, and it is important that it blends well with the other interior components. Renewal by Andersen® of Central Illinois, home of local window installation pros, share tips on how you can do so.

Consistency Is Key

The design of your windows’ casing, together with the trim found inside your home, must follow that of your home’s architectural style. Consistency is key here, whether the quantity of trim is greater in one room than in the other. Take note, however, not to oversupply every room with it as doing so can detract from the interior’s overall appeal.

Matching Trim Elements

Trim designs for every area of the interior must match well with one another. For example, the casings surrounding your windows must not be thicker than the baseboard and the chair rail. The end of a plate rail that meets the horizontal window casing must be finished with a return to cover the end grain.

Designing Within Proportions

The size of each interior trim and molding should be proportionate to the size of each room. Establishing this, however, can be quite a challenge. Our design team at Renewal by Andersen of Central Illinois can guide you with this if you don’t trust your own eye to determine the scale and proportion of the window trim.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
