Glaziers
Glaziers install glass in windows, skylights, storefronts, and display cases to create distinctive designs or reduce the need for artificial lighting.
Glaziers typically do the following:
- Follow blueprints or specifications for size, color, type, and thickness of glass to be used
- Remove any old or broken glass before installing replacement glass
- Cut glass to the specified size and shape
- Make or install sashes or moldings for glass installation
- 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
Glass has many uses in modern life. For example, insulated and specially treated glass keeps in warm or cool air and controls sound and condensation. Tempered and laminated glass makes doors and windows more secure. The creative use of large windows, glass doors, skylights, and sunroom additions makes buildings bright, airy, and inviting. Glaziers specialize in installing these different glass products.
In homes, glaziers install or replace windows, mirrors, shower doors, and bathtub enclosures. They fit glass for tabletops and display cases. On commercial interior projects, glaziers install items such as heavy, often etched, decorative room dividers or security windows. Glazing projects also may involve replacing storefront windows for supermarkets, auto dealerships, banks, and so on.
Workers who replace and repair glass in motor vehicles are not covered in this profile. For more information, see the profile on automotive body and glass repairers.
For most large scale construction jobs, glass is precut and mounted into frames at a factory or a contractor's 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. In cases where 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.
A few glaziers work with plastics, granite, marble, and other materials used as glass substitutes. Some work with films or laminates that improve the durability or safety of the glass.
Janitors and Building Cleaners
Janitors and building cleaners keep many types of buildings clean, orderly, and in good condition.
Janitors and building cleaners typically do the following:
- Gather and empty trash and trash bins
- Clean building floors by sweeping, mopping, or vacuuming them
- Clean bathrooms and stock them with soap, toilet paper, and other supplies
- Keep buildings secure by locking doors
- Clean spills and other hazards using sponges and squeegees
- Wash windows, walls, and glass
- Order cleaning supplies
- Make minor repairs to the building, such as changing light bulbs
- Notify managers when the building needs major repairs
Janitors and building cleaning workers keep office buildings, schools, hospitals, retail stores, hotels, and other places clean, sanitary, and in good condition. Some do only cleaning, while others have a wide range of duties.
In addition to keeping the inside of buildings clean and orderly, some janitors and building cleaners work outdoors, mowing lawns, sweeping walkways, or shoveling snow. Some janitors also monitor the heating and cooling system, ensuring that it functions properly.
Janitors and building cleaners use many tools and equipment. Simple cleaning tools may include mops, brooms, rakes, and shovels. Other tools may include snowblowers and floor buffers.
Some janitors may be responsible for repairing small problems with electricity or plumbing, such as leaky faucets.
