Millwork is a type of carpentry that refers to any construction material that was made in a sawmill and built into the home, like wall and door trim. It is a custom-made woodwork that comes from within a mill where the cutting and construction of items is with raw lumber. Millwork is different from casework in that it is fully customizable for the more subtle aspects of a buildings design, such as shelving, cabinetry, custom storage, and more. Millwork products include cabinetry, crown moldings, wall paneling, doors, trim, and molding. Millwork is typically more decorative than structural, and it is designed to be installed with very little modification. Some millwork products may incorporate steel, aluminum, or even glass. It is important to note that not all products made in a sawmill qualify as millwork, such as flooring.
