Commercial Window Cleaning • Some roofs on buildings do not have enough roof anchors or “tie off points”, therefore, the commercial window cleaning company has to use mobile roof anchors. Exterior window cleaning can be done with the use of a “Bosun’s Chair” In these cases. A Bosun’s chair is an apparatus that keeps the window washer suspended in the air in order for them to clean high rise windows. The Bosun’s chair is usually just a plank of board or a piece of heavy material such as canvas, that is connected to ropes or chains—not unlike the same type of harnesses used when rock or mountain climbing. • Another way commercial window washers clean a high-rise building is with the use of scaffolding. Scaffolding, is a device that is constructed temporarily to assist construction workers or window washers in doing their job in areas that are too high for a standard ladder. Scaffolding can be dangerous to use if it has not been constructed with the proper safety measures in place.
