Clean and well-maintained glass and façade surfaces reflect the "business card" of a successful company. They symbolise the self-image of the company and make a convincing argument both internally for employees as well as externally for customers and visitors. When combined with careful interior maintenance, shining external surfaces certainly represent a corporate culture that is a positive one.
However, general environmental pollution, acid rain or bird droppings can cause permanent damage to these external surfaces. Graffiti can often spoil the look of the façades as well. Regular cleaning and maintenance will however help to preserve a positive aesthetic effect, leaving the glass and façade surfaces shining once again and protecting them from corrosion and weathering.
