A stonemason is a skilled craftsperson who works with natural stone to build and repair structures. They cut, shape, and fit stones to create walls, buildings, fireplaces, monuments, patios, and decorative features. Some stonemasons specialize in restoration, carefully repairing historic buildings and stone monuments. Others focus on new construction, installing stone veneers or structural stonework. They use both traditional hand tools like chisels and hammers, as well as modern power tools. The job requires precision, physical strength, and knowledge of materials, measurements, and safety practices.
