Crown moldings are decorative trim pieces installed at the junction where walls meet ceilings. They add an elegant touch to a room and can enhance its overall aesthetic. Available in various styles, materials, and sizes, crown moldings can complement both traditional and modern interior designs. Typically made from materials like wood, MDF, or polyurethane, crown moldings can be painted or stained to match the room's decor. Installation can be done by professionals or as a DIY project, requiring precise measurements and cutting to ensure a seamless fit.
