Janitors and building cleaners typically do the following:

• Gather and empty trash
• Sweep, mop, or vacuum building floors
• Clean restrooms and stock them with supplies
• Lock doors to secure buildings
• Clean spills and other hazards with appropriate equipment
• Wash windows, walls, and glass
• Order cleaning supplies
• Make minor building repairs
• Notify managers when a building needs major repairs

Janitors and building cleaners keep office buildings, schools, hospitals, retail stores, hotels, and other places clean, sanitary, and in good condition. Some only clean, 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, and removing snow. Some workers also monitor the building's 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, floor buffers, and carpet extraction equipment.

Some janitors are responsible for repairing minor electrical or plumbing problems, such as leaky faucets.

The following are examples of types of janitors and building cleaners:

Building superintendents are responsible for maintaining residential buildings, such as apartments and condominiums. Although their duties are similar to those of other janitors, some building superintendents also help collect rent and show vacancies to potential tenants.

Custodians are janitors or cleaning workers who typically maintain institutional facilities, such as public schools and hospitals.
