It's usually the first thing visitors to your business see: the outside of the building. With clean windows and a neat facade. When assessing a company or organization, visitors also look at the appearance of a building. Professional and regular cleaning and maintenance of glass and facades contribute to a longer lifespan of the building and prevent high (unexpected) costs. Not only the outside of your building is important, the glass on the inside is just as important for creating a positive experience for employees and visitors.
