As a glass installer, also known as a glazier, your duties are to cut windows to fit within frames, replace broken windows, and install new windows for renovations or construction projects. Your responsibilities include ensuring that a window product fits correctly and works efficiently for customers. You can work with a variety of products that need windows, including showers, vehicles, homes, sheds, and businesses. These positions require some travel to meet with customers and install windows, but you can do most glass cutting projects in a factory or workshop. Most of these positions are full-time, but some can be on a contract basis.
