Janitor

A janitor, janitress(female), custodian "cleaner" or caretaker (British English (except Scotland)) is a professional who takes care of buildings such as hospitals, schools and residential accommodation. Janitors' primary responsibility is as a cleaner and in some cases they will also carry out maintenance and security duties. A similar position, but usually with more managerial duties and not including cleaning, is occupied by building superintendents in the USA.
