External facade cleaning refers to the process of eliminating dirt, grime, stains, and pollutants that accumulate on the front half of a building, known as the facade. The facade serves as the entrance to the building and can be constructed using various materials such as glass, stone, wood, or metals like stainless steel or aluminum.

Multiple factors can contribute to the deterioration of a building’s facade, resulting in a dirty appearance. Adverse weather conditions and airborne contaminants are among the primary causes. This combination can lead to a loss of color and negatively impact the overall aesthetic of the facade.

The facade plays a crucial role in enhancing the visual appeal of a building. A well-maintained and attractive exterior is more inviting than a neglected one. It creates a friendly and welcoming atmosphere, setting a positive tone for the entire building and the associated business.

Facades are constructed using materials like stone, brick, concrete, glass, or metal, chosen to complement the overall architectural design. However, without regular care and maintenance, even the most exquisite elements such as polished stone or gleaming metal can become unsightly instead of a source of delight.

Maintaining the facade of your rented building is equally important as an owner. It is possible that your rental agreement includes provisions stating that the exterior of the building should always be kept clean, making it crucial for you to adhere to this requirement.
The unique and intricate contours created by the facade can become habitats for insects, animals, and rats. These nests not only pose a nuisance but can also be hazardous, and the droppings they leave behind result in unsightly stains.

Types of Facade Maintenance

There are various maintenance methods available, and their suitability depends on factors such as the building type and height:

Pressure washing: This method involves utilizing a high-pressure washer, often with the assistance of ropes, to eliminate dirt from the facade. It is typically a fast and environmentally friendly approach, as it utilizes pressurized water instead of cleaning solutions. However, it may not be suitable for all building materials.

Moss control: Moss control entails applying substances designed to control moss to problem areas on the facade. Subsequently, any remaining moss can be rinsed off using gentle pressure washing or left to be naturally washed away by rain.

Specialized washing: This method is specifically employed for facades that have particular types of paint or plaster on their surfaces. It utilizes a higher-pressure washer in combination with a specially formulated cleaning agent to effectively clean the facade.

Lightbox advertisement/logo washing: This maintenance technique is commonly used for cleaning lightbox advertisements or logos on the facade. Telescopic poles with brushes at the top are employed, and clean filtered water is streamed onto the advertisement or logo. The dirt is then rubbed off the surface.

It’s important to note that the choice of maintenance method should consider the specific requirements and materials of the building’s facade. Consulting with professionals in facade maintenance is recommended to determine the most appropriate approach for a particular building.
