As you can see from the window trim photos, there are many types of extra exterior treatments that you can add to a window to really complete the finish of a home. Without these exterior opening trim pieces, the job may seem incomplete, or bare (unless you are going for that minimalist look).

The 2 most common features to add are window casing and window sills, and after that possibly window jambs. Typically a casing will be 6-8 inches for standard, and a sill of 4-8 inches.

A good tip when getting cast stone window sills is to go with a larger profile, and have a fairly standard casing profile. A larger sill profile that tapers down from quite wide to quite narrow makes a big impact. Whereas a simple sill really looks quite boring.

“One of the features often overlooked when designing a ‘new old house’ is the window style,” says Mark Montgomery, vice president of marketing for Ply Gem Windows. “Instinctively, people realize the curb appeal of a home is not quite right when the windows do not fit the architectural style, but they can’t point out what’s wrong. Windows are so much more than white rectangles and can really make or break the home’s design.”
