From a maintenance perspective, glass on commercial buildings isn’t any different than the stuff in your home. It will generally keep functioning as intended now matter how dirty it gets, though you won’t be able to see very well out of it.
However, most business owners and managers want to keep the glass on their establishments a bit cleaner than the glass on their homes for a few reasons.
For one, a slick, clean, shiny looking glass curtain wall on an office building just looks nice and professional.
It gives off the sense that the building is a clean, well-maintained place and that implies that the businesses working inside of that building are themselves conscientious, capable and self-respecting. Regular commercial window cleaning can help a business make an unspoken statement to its customers and clients.
Another reason? Consider the effect that a clean, well maintained building will have on the people who work in it. Most people don’t want to work in a sloppy, rundown office. Regular commercial window cleaning can create the subtle impression on employees entering a building that this is a serious place where dedicated people do business that matters.
Of course there is much, much more to a successful business than clean glass, but exterior glass curtain walls that are regularly cleaned by a commercial window cleaning service can be an important part of creating a good impression on customers, clients, and employees!
