It's usually the first thing visitors to your business see: the outside of the building. With clean windows and a neatly maintained facade. Visitors also include the appearance of a building when assessing a company or organisation. Professional and periodic cleaning and maintenance of glass and facades contribute to a longer lifespan of the property and prevent high (unexpected) costs. Not only the exterior of your building is important, because the interior glass is just as important for a positive experience for employees and visitors.
