Stucco Keystones add a unique flare and style to windows and doors. Our lightweight stucco keystones can be installed either during new construction or after a renovation, and will not rot, warp, or become infested. The size of a keystone will be determined by the trim you're using it with, keystones should generally be 1-2 inches taller than the trim to provide enough visual impact. The shape or design of the keystone is largely a personal preference, and should generally fit with the style and theme of the home.

Keystones have been used in construction projects for thousands of years, and while they're no longer required structurally, they provide a classic, timeless look to any project. They can be used on any building material including brick, stone, stucco, EIFS and even vinyl.

When selecting the placement of keystones, you want to first start with the most often seen doors and windows, and fill in the rest as budget and time permits. A few key places include the front door, garage doors, and large windows on the front of the home. Smaller or less ornate keystones can be used on dormers and less prominent or visible windows.

Keystones are designed to be embedded into stucco trim!

You want to choose your keystone size based on the size of your stucco trim - the winged portions should protrude just slightly above the trim itself. Most keystones are designed with a larger depth, to accommodate trims of various sizes. If you received a keystone on site that doesn't match the depth of the trim, it can be padded outward by simply using a piece of flatband or styrofoam trim.

Although purely decorative, keystones are a a great way to accent your windows and doors. Keystones should be initially placed when installing the rest of the molding and window trim, however - a center can be carefully cut from existing moldings to provide a place for keystones.
