The structural punctuation of interior design is trim and molding. They determine the boundary of one surface to another, create visual weight and personality to bare walls, and provide a space with a sense of purpose and completeness that cannot be obtained through paint alone. Properly applied interior crown molding painting attracts attention upwards and makes ceilings appear taller. Baseboards are crisp and keep a room grounded, and provide a clean transition between the wall and floor. The openings are framed with sharp door and window casings that have a finished architectural appearance that takes the whole interior a step higher. Trim that is dingy, cracked, or that has years of scuffing and build-up of paint weakens all that surrounds it. New, well-painted trim freshens things up. It rejuvenates the whole aesthetic of a room and transforms rooms that remain structurally the same but are much more modern and sophisticated.
