A number of aspects can affect the methods employed by commercial window cleaning companies. Height of the building and access are the main ones. All the staff in the companies needs to have special training to operate at heights and risk is another factor in deciding the appropriate technique. The traditional window cleaning style with a ladder and a squeegee is still used but when this is not possible there a number of other methods which can be employed.

For lower windows the water fed hose technique is ideal. It has several advantages over the traditional method. Firstly the pole can reach places which a ladder cannot such as above flower beds. The water used is purified which means that it attracts dirt so the process uses less detergent. Also after washing the hose rinses the glass and no further wiping is needed as the pure water dries without smears. The method is quicker because less washing is needed and also the worker does not have to get up and down ladders. It also does not damage buildings at all as there is no equipment to attach and also disturbs the occupants less. The poles usually reach to around twenty meters.

There are three methods used for high buildings. If a building has enough space with places at the top to attach pulleys then the cradle method can be employed. It is better for large buildings as it takes time to set up the equipment and maneuver it.

For buildings which are clear of obstructions, both on the ground and around the sides a cherry picker can be used. This can also be called a mobile platform. The vehicle which hoists the platform is fairly large so there must be a lot of clear space around the building. To hire this machinery is not cheap so this can be an expensive option but it is safe.

For ease of access and speed the abseiling technique has become very popular. The workers can get to places that those on large equipment cannot reach. It is quicker because there is not a lot of machinery and the worker has unrestricted access to the windows. For all three techniques special courses must be taken.

There are many window cleaning companies on the internet who can provide the full range of services according to your needs. There are also websites with directories of providers so you can quickly find the ones in your area.
