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

Duties

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.

Work Environment

Glaziers held about 56,900 jobs in 2021. The largest employers of glaziers were as follows:

Foundation, structure, and building exterior contractors 63%
Building material and garden equipment and supplies dealers           11
Self-employed workers 8
Building finishing contractors 6
Manufacturing 4

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.

Education and Training

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

Education

Glaziers typically need a high school diploma or equivalent to enter the occupation.

Training

Glaziers typically learn their trade through a 3- or 4-year apprenticeship or on-the-job training. On the job, they learn to use the tools and equipment of the trade; handle, measure, cut, and install glass and metal framing; cut and fit moldings; and install and balance glass doors. Technical training includes learning different installation techniques, blueprint reading and sketching, general construction techniques, safety practices, and first aid.

A few groups sponsor apprenticeship programs, including several union and contractor associations. Most programs require apprentices to have a high school diploma or equivalent and be at least 18 years old. After completing an apprenticeship program, glaziers are considered to be journey workers who may do tasks on their own.

Licenses, Certifications, and Registrations

Some states may require glaziers to have a license; check with your state for more information. Licensure requirements typically include passing a test and having a combination of education and work experience.

Glaziers may choose to get optional certification, such the Architectural Glass and Metal Technician (AGMT), to demonstrate competency and to broaden employment opportunities. 

Personality and Interests

Glaziers typically have an interest in the Building and Organizing interest areas, according to the Holland Code framework. The Building interest area indicates a focus on working with tools and machines, and making or fixing practical things. The Organizing interest area indicates a focus on working with information and processes to keep things arranged in orderly systems.

If you are not sure whether you have a Building or Organizing interest which might fit with a career as a glazier, you can take a career test to measure your interests.

Glaziers should also possess the following specific qualities:

Balance. To minimize the risk of falling, glaziers need a good sense of balance while working on ladders and scaffolding.

Hand-eye coordination. Glass must be precisely cut. As a result, a steady hand is needed to achieve a cut of the correct size and shape.

Physical stamina. Glaziers must be on their feet and move heavy pieces of glass most of the day. They need to be able to hold glass in place until it can be fully secured.

Physical strength. Glaziers must often lift heavy pieces of glass for hanging. Physical strength, therefore, is important for the occupation.

Pay

The median annual wage for glaziers was $47,180 in May 2021. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $30,470, and the highest 10 percent earned more than $79,340.

In May 2021, the median annual wages for glaziers in the top industries in which they worked were as follows:

Foundation, structure, and building exterior contractors $47,750
Building finishing contractors 46,660
Building material and garden equipment and supplies dealers           45,400
Manufacturing 37,840

Pay for apprentices is less than what fully trained glaziers make. Apprentices receive more pay as they gain experience. Glaziers who work at heights may be eligible for hazard pay.

Most glaziers work full time.

Job Outlook

Employment of glaziers is projected to grow 4 percent from 2021 to 2031, about as fast as the average for all occupations.

About 6,500 openings for glaziers are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire. 

Employment

An important component of buildings, glass improves access to natural light. Demand for glaziers stems both from new construction and from the need to repair and replace windows and other glass in existing buildings.
