Molding & Finish

Whether you're looking to replace existing moldings, update to a new look, or build new, trims and moldings give your home a finished look. We carry a wide variety of casings, door headers, crown moldings, and even plinth and corner blocks! Ask your sales representative about all of our delivery options when ordering your materials.
