When and how should windows at height be cleaned?

Window cleaning at height for hotels and office buildings needs to take account of the building’s requirements, weather conditions and access options. For spring or pre-season cleaning, it is advisable to book in advance. The access method, whether rope access or a mobile elevating work platform, is selected according to the characteristics of the building.

When choosing a cleaning method, it is important to consider the surface material, the level of soiling and access to individual sections of the façade. These factors also influence maintenance frequency and the cost of the work.

When to book spring or pre-season cleaning

It is advisable to arrange cleaning before the start of the hotel season or important business events. Larger buildings require sufficient time to assess the scope of work and coordinate scheduling. At Alterra Grupa, we recommend booking spring or pre-season cleaning as early as January or February.

Work is scheduled to suit conditions at the site. Wind, rain and other weather conditions can affect the work, so scheduling should allow for possible changes to the agreed dates.

Window cleaning using rope access or an elevating work platform

Rope access technicians use ropes to reach exterior surfaces. This method can be suitable for cleaning hard-to-reach windows and glass façades, particularly where access from ground level is restricted. Its suitability depends on the availability of safe access and anchorage points on the building.

Window cleaning using a crane with a personnel basket or a mobile elevating work platform is an option where suitable access, space and ground conditions are available. Some buildings may require a combination of access methods. The choice depends on an assessment of the building, rather than its height alone.

Glass maintenance and façade cleaning

At hotels, glazed entrances and glass façades help shape guests’ first impressions. In office buildings, clean windows contribute to a well-maintained appearance for employees, tenants and clients. Cleaning frequency is adjusted according to exposure to traffic, dust and other sources of dirt.

Rope access can also be used to clean façades and other hard-to-reach exterior surfaces. The cleaning method is adapted to the material and condition of the surface. Glass, stone and clad surfaces may require different cleaning products and techniques.

What determines the cost of window cleaning at height

The cost of window cleaning at height depends on the area of glass, its accessibility, the access method and the level of soiling. Another factor is whether the service covers only the glass or also includes frames and other parts of the façade.

An accurate quotation requires information about the building and, in some cases, a site visit. When comparing quotations, it is important to check that they cover the same surfaces and scope of work.
