Custodian vs. Janitor: The Basics

What Is a Janitor?

The word janitor comes from the Latin word janua, meaning door. Traditionally, a janitor was someone who was responsible for a building’s doors and overall cleanliness.

In modern English, a janitor usually refers to a person who:

Cleans and maintains buildings such as schools, offices, hospitals, or apartment complexes.
Sweeps floors, empties trash cans, cleans bathrooms, and washes windows.
May do some minor repairs or maintenance tasks, but the main focus is cleaning.

Janitor is a very common word in American English. You often hear it in schools (“the school janitor”), office buildings, and other public places.

Example sentence:

The janitor cleans the classrooms every evening.
If you have a spill, please call the janitor to help.

What Is a Custodian?

The word custodian comes from the Latin custodia, meaning guard or protection. This already shows a slightly different focus compared to janitor.

In modern English, a custodian can mean:

Someone who is responsible for cleaning and maintaining a building, similar to a janitor.
Someone who takes care of and protects property.
A person who manages or looks after something valuable, such as money or important documents.

Because of these additional meanings, the word custodian often carries a sense of caretaking, stewardship, and responsibility. It can sound more formal or professional than janitor.

Example sentence:

The custodian of the museum ensures that all the exhibits are safe and clean.
As the custodian of these funds, she manages them carefully.

In schools or universities, custodian is sometimes preferred because it shows more respect for the role, emphasizing that it is not only about cleaning but also about taking care of the facilities.
