Frequently Asked Questions

What is the difference between a janitor and a custodian?

A custodian often has broader duties than a janitor, including managing keys, supplies, and security, especially in schools. A janitor typically focuses strictly on cleaning floors and trash. While the tasks overlap, the custodian role often implies more administrative responsibility.

Is janitor a formal word?

No, janitor is a standard, neutral word used in everyday language and job titles. For more formal contexts like business reports, facilities manager or maintenance worker are preferred alternatives that sound more professional and encompass a wider range of duties.

What are some slang words for janitor?

Common slang terms include cleaner, mop guy, or floor sweeper. These words are informal and usually used in conversation rather than official documents. Some people might also use porter or shiner depending on the specific type of building they work in.

Do janitors do repairs?

Yes, many janitors perform minor repairs like changing light bulbs or unclogging drains. However, their primary job is cleaning. If the building requires major structural work, a separate maintenance worker or technician usually handles those specific technical issues.
