Moulding & Trim

Shop OnlineShop Online


From the clean sophisticated lines of painted trim to the timeless quality of solid wood, mouldings are the final touches that enhance any room with a finish that expresses your personal style. Revive a room by replacing the casings and baseboards, or add a wow factor with a crown or chair rail.

Doors have many responsibilities in a home. They represent a significant portion of wall space inside and regulate how rooms flow. They are also the crown jewel of a good interior design. Interior doors are available in wood or composite, and are available with a myriad of glass panel sizes, shapes, textures and decorative patterns.
