Building facade cleaning
Due to the increasing prevalence of tall buildings and the thriving life in industrial cities, air pollution and contaminated particles in the air have caused significant harm to humans, affecting their lives and those around them. Various elements in industrial and chemical pollutants cause building facades to become unsightly and unattractive. Today, because most residential and commercial buildings are very tall and exposed to air pollution, their facades have become very unattractive, creating an unpleasant and discordant environment. If these facades are not maintained and cleaned, they contribute to the ugliness of the city, buildings, and neighborhoods. Building facade pollution can affect various types of facades, including composite, stone, brick, sandstone, and glass facades. If cleaning is neglected, it ultimately leads to the erosion of the building and facade, resulting in substantial costs.
Building facade cleaning is a modern method that has gained significant traction today. Traditional methods are no longer used, but with the adoption of new techniques and the development of numerous machines in this field, building facade cleaning has been greatly facilitated. In the following sections, we will introduce you to various methods of building facade cleaning. For more information, read the text below to learn about the features of different facade cleaning methods.
Types of facade cleaning

Cleaning of various facades
Methods of facade cleaning using water are effective when there isn’t much dirt or grime on the facades, allowing them to be cleaned with just water. Another method involves combining water and silica, which effectively removes stains and grime. For the numerous lime deposits from acid rain on building facades, acid washing is used. As the name suggests, it involves using specific cleaning tools and agents to remove stains and grease.
Cleaning glass facades with an industrial water jet, using high pressure powered by a motor worn on the worker’s back, eliminates any pollutants, grease, or grime clinging to the facade. This equipment is quite heavy, and its use may cause back and neck pain. Water jets can use either hot or cold water; in highly polluted buildings, hot water jets are used because hot water is very effective in removing grease.
One of the methods for cleaning building facades involves using glass and composite facades. Sponge and squeegee are essential tools for facade cleaning. The worker hangs from the window and cleans the facade in two steps. First, they apply foam to the facade, and before it dries, they rinse it off with water to remove the foam.
Costs and prices of building facade cleaning
The costs and prices of building facade cleaning depend on the rates for that year. The larger and taller the building, and the dirtier, more polluted, and greasier the facade, the higher the cost will be. If the cleaning is done using scaffolding, the price will definitely be higher. If the facade is made of glass or stone, the cost will be more expensive because glass facades require careful cleaning to ensure no stains are left. Typically, a contract is signed with the company before the cleaning starts, which significantly influences the price. If you need to repair the glass during the cleaning, the cost will multiply, but if repairs are not made, it can lead to higher expenses later on.
The payment for cleaning is usually done in various ways. The most common method is to initially pay one-third of the agreed amount to the worker, then pay the remaining balance after the work is completed. In some cases, the payment is made in installments.
Glass facade and building surfaces with water jet
Facade and surface cleaning with water jet is one of the best methods used today for buildings exposed to rain, wind, storms, air pollution, and acid contamination. This cleaning method, using a water jet, is cost-effective but poses significant risks to the person performing the task. There are various devices available for facade washing and cleaning.
- Cold Water Jet
- Hot Water Jet
- Electric Water Jet
- Gasoline Engine Water Jet
- Central Fixed Water Jet
Cleaning facades without the use of scaffolding is done with long, sturdy ropes. In this method, the worker carries a high-pressure water jet in a backpack and cleans all the dirty facades. Each water jet device can spray and release water at a pressure of 300 to 400 bar. This device is used for very tall towers, stone facades, brick facades, cement facades, silica facades, wall facades, and floor cleaning.
Why is facade cleaning performed?
Cleaning is performed for various reasons. Firstly, it removes any contamination, such as dust that settles on the building facade. A clean facade enhances the building’s appearance and contributes to the overall beauty of the city. In many buildings, cleaning is part of construction projects. The method of facade cleaning depends on the type of facade. For buildings with a maximum of four floors, traditional cleaning methods using cleaning solutions are employed. However, for multi-story facades, scaffolding and water jets are used.
For example, glass and composite facades are cleaned using water jets, detergents, and sponge and squeegee methods. These facades typically require cleaning twice a year. Stone facades are cleaned with water jets and usually need cleaning once a year. Brick facades also require cleaning with water jets.
