More complex tasks and higher pay are usually given to those who have gained experience and have proven themselves to be efficient and dependable workers. If the custodian is the only maintenance employee in a building, advancement opportunities are limited. Supervisory positions are possible, on the other hand, for those who work on a large maintenance staff, especially for those who hold a high school diploma. Janitors may become building superintendents, janitorial services supervisors, or custodial supervisors. With additional training in real estate and managerial skills, the ambitious custodian may eventually move into property management. Some experienced custodians establish their own contract cleaning and maintenance businesses, providing services to a number of clients. This requires some administrative and supervisory skills as well as the ability and resources needed to start and grow a new business.
