A glazer is a tradesperson who installs, repairs, and replaces glass in windows, doors, and other structures. They work with various types of glass, including safety, decorative, and insulated glass, in residential, commercial, and industrial settings. Glazers measure, cut, and secure glass using specialized tools and techniques. Their job also involves working with frameworks, sealants, and sometimes lifting heavy materials. Safety is a key concern, as glazers often work at heights and handle sharp materials.
