Crown molding is a decorative trim installed where walls meet the ceiling to add an elegant finishing touch to rooms. It's a specialized carpentry skill that combines both functional and aesthetic aspects of woodworking. Carpenters who work with crown molding need to understand various installation techniques, material types (like wood, MDF, or polyurethane), and must be skilled at making precise angle cuts. This detail work is similar to other trim carpentry tasks like installing baseboards or chair rails, but is generally considered more complex due to the angles involved.
