Crown molding is a decorative trim used to enhance the appearance of the junction between walls and ceilings. Typically made from materials like wood, plaster, or polyurethane, it adds an elegant touch to any room. Crown molding comes in various styles and sizes, allowing homeowners to choose designs that complement their interior decor. Installing crown molding can create a sense of height and sophistication in a space. It can also help to hide imperfections where the wall meets the ceiling. While it can be a DIY project, many people opt to hire professionals for a precise and polished finish.
