Cornices-Building is a subdivision of the Roofing, Siding, and Sheet Metal Work industry that specializes in the design, fabrication, and installation of decorative and functional cornices for buildings. Cornices are ornamental moldings that are typically installed at the top of a building's exterior walls, where the roof meets the wall. They serve both an aesthetic and functional purpose, as they help to protect the building's exterior from water damage and provide a decorative element to the building's design. The process of creating and installing cornices involves a range of specialized skills and equipment. Cornice builders must have a strong understanding of architectural design and be able to work with a variety of materials, including wood, metal, and plaster. They must also be skilled in the use of specialized tools and equipment, such as metal brakes, saws, and lathes. Cornices-Building companies typically work closely with architects, builders, and property owners to design and fabricate custom cornices that meet the specific needs and aesthetic preferences of each project. They may also provide repair and restoration services for existing cornices, as well as installation services for new construction projects.
