How do you clean the top windows of a multi storey building if they don't open?

Answer 1

you not seen the old diet coke adverts? 'it's 1130!'

Answer 2

There are a number of ways this can be done. It depends on the height of the building, the available space along the line of the building the windows are, and the amount of money to be spent on window cleaning/maintenance.

Typically a commercial building would have some sort of window cleaning/maintenance regime designed in. Whether this is by having windows that open inwards, or in the case that you are asking about, window cleaning gondolas can also be installed. These window cleaning gondolas can come in different forms, but typically they are suspended from hangers which are in turn secured to rails along the roof of the building.

If gondolas have not been designed and installed as part of the building maintenance regime, a number of options are still open. If the windows to be cleaned are within 60ft of the adjacent pavement, and there is sufficient clearance from the building face, a reach-and-clean cleaning system can be used. This comes in the form of a very long pole with a cleaning sponge/squeegee, a long hose and a pump. A man on pavement level cleans the glass by pumping soapy water via the pump onto the sponge/squeegee at the end of the pole.

Another method is by the use of a MEWP (mobile elevated working platform). These come in varying forms, from the lightweight scissor lifts all the way up to truck mounted cherry pickers. Again, selection of the actual MEWP to be used depends on the height to be reached, available space and budget. Also, the loading capabilities of the structure and surface adjacent to the building face is a major consideration (for example, you wouldn't want to use a heavy truck mounted cherry picker if the adjacent ground is soft landscaping as the truck would just sink and get bogged down).

One other method, now in more increasing use, is by roped access. Specially trained technicians find and use all available anchor points on the roof to abseil down to the windows to be cleaned. This method originated from industrial roped access used on oil rigs and smoke stacks is now being used on many buildings.

Answer 3

a guy on a crane platform is lowered down the outside of teh building with a winch mechanism, it can be very dangerous at times of high winds and still doesnt pay all that much really

some buildings are now fitted with self cleaning windows that clean themselves when it rains but still need to be cleaned really

Answer 4

You come down from the roof of the building in a large cage, you wear a harness too even though you are in the cage, and you lower yourself via the cage ropes from floor to floor.

Answer 5

In a window cleaning cradle from the outside. Or just replace the glass.

Answer 6

You will need to get one of those outside lift thingy's for someone to clean the outside, and just clean the inside as well, I hope this helps?

Answer 7

They use scafolding and a winch system to lower a cage down and clean them by hand

Answer 8

Windex makes a product that attaches to a garden hose. Then all you do is hose them down.

Answer 9

usually absailling down the building, some buildings have their own baskets lowered from roof.
