Cleaning high-rise windows is nothing like cleaning the windows of your house or bedroom, which only needs a damp cloth, a squeegee, some window cleaning detergent or a bucket of soapy water and some elbow grease! When you’re cleaning windows on the floors of a skyscraper, at the dizzying height of half a mile above the ground, things take on a drastically different feel.

Cleaning skyscraper windows is a dangerous job and not for the faint-hearted. It takes a certain type of person to be able work at heights way above the ground. Skyscraper window cleaners are skilled professionals, aware of the perils of their job. One slip or mistake and people could die, so safety is always foremost in window cleaners’ minds. Safety drills are performed regularly and everyone knows exactly what to do while suspended high up in the air.

Wind can play a big part too. Way up on the side of a skyscraper, winds generally blow at a much greater speed than down on the ground, which makes it absolutely vital for cleaners to be equipped with the relevant safety equipment.
