Advance Cleaning has been responsible for the window cleaning at 30 St Mary Axe since 1st January 2006. During this period they have offered an excellent level of regular management support and information linked with first class service delivery. In particular their proactive innovative problem solving of access issues has been a great benefit to us. The operational team is very well supported at all times by the Directors who all play an active role in running the business.
