Trim work refers to the finishing touches in a building's interior or exterior, enhancing its overall appearance. It includes elements like baseboards, crown molding, and window casings, which frame doors and windows, providing a polished look. Trim work can be made from various materials, including wood, MDF, or vinyl, and is often painted or stained to match the decor. In addition to aesthetics, trim work serves practical purposes, such as covering gaps between walls and floors. It can also help protect surfaces from wear and tear. Properly installed trim adds value to a home and contributes to its architectural style.
