There is no such thing as a typical glazing project. One day you could be called out to replace a single broken pane of glass in a domestic front door; and the next you might be working at fifteen stories, fitting new emission controlling glass to a modern office block. A Glazier measures, installs and replaces different types of glass in a variety of situations. Glaziers can specialise in residential work which consists of installing glass in windows. Alternatively they may work on industrial sites replacing display windows in shops, car dealerships, offices, banks and other buildings. Glaziers might also help in the construction of large office buildings by constructing metal frames and then putting in large sheets of glass or glass walls.
