Behind the scenes we are responsible for the cleaning and maintainance at many of Britain's highest profile and heavy volume traffic areas. With over 3,500 employees across the UK, Blue Diamond really is a gem of a resource when heavy (and often disrespectful) traffic and sometimes 24 hour constant usage are part of everyday life.
