Janitors perform building maintenance duties. They perform minor repairs (e.g., carpentry and plumbing), maintain the plumbing, heating and ventilation systems, and ensure the safety and sanitation of the premises. As part of their duties, they may be responsible for managing certain aspects pertaining to rentals, complaints, rent, etc. This job requires good manual skills and resourcefulness. A job as a janitor is suitable for people who enjoy maintaining good neighbourly relations but who also like to work alone.
