Baseboard is a type of trim found at the bottom of walls in many homes. It is usually made of wood and is often decorated with molding or DADO. Molding is a decorative strip of material, such as wood or plaster, that is used to cover the joint between two surfaces or to decorate a surface. DADO is a groove cut into a wall or other surface to provide a recess for a shelf or panel. Both molding and DADO are commonly used to enhance the look of baseboard.
