High Rise Window Cleaners Put On A Show

By Stella Gay


You have a tall building with a lot of window glass. The biggest problem you have is getting all of the glass cleaned on a regular basis. It needs to be cleaned because the wind and rain will bring much contamination to the surface and the glass can become filthy and you and your employees ability to see out is diminished. Depending on the height of your structure, you may need to hire a company who has high rise window cleaners.

Dealing with cleaners who do the washing on the first floors is one thing. They take care of the glass with the few tools they need and, maybe a short pole. Occasionally they will need to use a scissor lift if a flat surface is next to the structure. Sometimes these cleaners will use a pole that has self contained cleaning solution piped to the head.

The second floor glass can be cleaned with use of a scissor lift. Any floor higher than that, from second to third and, occasionally, a fourth floor, can be cleaned using a boom truck. This machine has large tires and an extended boom, as long as 65 feet and can hold one or two cleaners for those hard to reach windows.

Most high rise buildings have the anchors needed already located on the roof and take many forms. One of the most unpopular rigging is that which allows for the cleaners repelling down the side of the building. You may have seen these rigs with a window cleaner in them. They are composed of a set of ropes and chains which suspend a type of chair. This is usually a flexible bucket that will hold the expert securely.

The rope that is used to allow for this repelling system to work is anchored to the roof. There are a set of block and tackle, which consists of a couple of pulleys that allow those ropes to be pulled up and down. There is a duplicate set attached to a flexible chair that the cleaner sits in. This chair is fabricated from ropes and hold the technician very securely. The pulleys that are at this level will allow the cleaner to move from one floor to the next and lock him in place when desired.

A very popular system is the gondola. This is a larger platform than can be allowed by the repelling system. The anchor on the roof is more complicated and usually run by a wench. The gondola, usually with more than one cleaner, is lowered by the use of these pulleys and electric motor to a floor and locked into place. It can be moved from that level, down to the next one when needed.

It does not matter what is used to get the cleaners up to the right level or down to the appropriate height. What does matter is that all of the cleaning is done in about the same way. The number of tools is the same and the process is the same. The tools consist of a wet bar, a bucket, a cloth or two and a squeegee. Many cleaners will also include a window knife for sticky substances.

The glass is made wet with the wet bar and scraped, if needed, with the knife. After this, it will probably be scrubbed, again, with the wet bar. The show, that many people stop and watch is the use of the squeegee. This is usually a very graceful swoop of the squeegee from the upper left, down the glass, through a swooping motion and finishing on the bottom and wiped with the cloth.
