Many building managers find that having a full or part-timeĀ portering and cleaning service is a great way to keep their property clean and tidy throughout the day. The porterĀ is responsible for keeping the buildings clean, dealing with spills, assisting with office moves, assisting with deliveries, opening and locking buildings and rooms as required, salting sidewalks and staircases in the winter-time, setting up and clearing down furniture for special events.
