What Glaziers Do

Glaziers install glass in windows, skylights, and other fixtures in buildings.

Work Environment

As in many other construction trades, the work of glaziers is physically demanding. They may experience cuts from tools and glass, falls from ladders and scaffolding, and exposure to solvents. Most work full time.

How to Become a Glazier

Glaziers typically enter the occupation with a high school diploma and learn their trade through an apprenticeship or on-the-job training.


The median annual wage for glaziers was $44,630 in May 2019.

Job Outlook

Employment of glaziers is projected to grow 4 percent from 2019 to 2029, about as fast as the average for all occupations. Job opportunities are expected from growth in the construction industry and from the need to replace glaziers who leave the occupation each year.

Glaziers install glass in windows, skylights, and other fixtures in buildings.


Glaziers typically do the following:

  • Follow blueprints and specifications
  • Remove any existing glass before installing replacement glass
  • Cut glass to the specified size and shape
  • Use measuring tape, plumb lines, and levels to ensure proper fitting
  • Make or install sashes and moldings for installing glass
  • Fasten glass into sashes or frames with clips, moldings, or other types of fasteners
  • Add weather seal or putty around pane edges to seal joints

Glaziers specialize in installing different glass products, such as insulated glass that retains warm or cool air and tempered glass that is less prone to breaking.

In homes, glaziers install or replace glass items including windows, mirrors, shower doors, and bathtub enclosures. On commercial projects, glaziers install items such as room dividers, display cases, and security windows. For either residential or commercial exterior projects, glaziers may install items such as architectural glass systems (glass used for exterior walls or other building material) or storefront windows in businesses.

For most large construction projects, glass is precut and mounted into frames at a factory or shop. The finished glass arrives at the jobsite ready for glaziers to position and secure into place. Using cranes or hoists with suction cups, workers lift large, heavy pieces of glass for installation. If the glass is not secure inside the frame, glaziers may attach steel and aluminum sashes or frames to the building and then secure the glass with clips, moldings, or other types of fasteners.

Workers who replace and repair glass in motor vehicles are described in the automotive body and glass repairers profile.

Glaziers held about 52,800 jobs in 2019. The largest employers of glaziers were as follows:

Foundation, structure, and building exterior contractors 69%
Building material and garden equipment and supplies dealers 14
Building finishing contractors 5
Manufacturing 5
Self-employed workers 1

As in many other construction trades, the work of glaziers is physically demanding. Glaziers spend most of the day standing, bending, or reaching, and they often must lift and maneuver heavy, cumbersome materials, such as large glass plates. Glaziers are often exposed to the weather while installing glass. They may be required to travel to different jobsites for commercial or residential work.

Injuries and Illnesses

The work of glaziers can be dangerous, and workers risk injury. Injuries may include cuts from tools and glass, falls from ladders and scaffolding, and exposure to solvents. To minimize their risk of harm, workers may wear protective gear, such as safety glasses, harnesses, and gloves.

Work Schedules

Most glaziers work full time.
