Doing trim work involves wood trim, or moldings, which are designed, constructed, and installed on a home or commercial space. Because it is often one of the last steps of remodeling or carpentry projects, trim work is also sometimes referred to as finish carpentry. Additionally, trim work can help connect loose ends left from rough carpentry, and can even add to the overall aesthetic design of a home. Trim work is essential for creating quality, “finished” look in a home. It’s common for homeowners to paint trim pieces to add depth to a room.
