Keystones and Trim Blocks

If your fireplace, door or window trim ideas call for the look of stone, our keystones and trim blocks can provide the perfect touch. You can create interesting architectural detail on an interior arched doorway or enhance exterior window casings to boost your home’s curb appeal.

Made from lightweight and durable polyurethane, the keystones and blocks are easy to handle and can be added anywhere. The material also won't fade, chip or crack and stands up to exterior elements with flying colors.

Take a look at these photos from past customers who’ve added the trim in various interior and exterior settings with beautiful, professional looking results.
