Facade Cleaning – Treatment & Sealing

What Is Facade Cleaning?

Facade cleaning is the process of cleaning and restoring the exterior surfaces of a building, such as walls, windows, and other architectural elements. It is an important maintenance activity to maintain the aesthetics and integrity of a building. Facade cleaning can be done using various methods, depending on the type of surface and level of dirt or stains.


Common methods of facade cleaning include pressure washing, chemical cleaning, steam cleaning, and abrasive techniques. Pressure washing uses high-pressure water jets to remove dirt and grime from the surface. Chemical cleaning involves the use of specific cleaning agents to dissolve stains and pollutants. Steam cleaning utilizes high-temperature steam to remove dirt effectively. Abrasive techniques involve using abrasive materials like sand or grit to scrub away stubborn stains.


Professional facade cleaners are trained in these methods and employ specialized equipment for effective and safe cleaning. They ensure compliance with safety regulations, protect surrounding areas from damage, and use eco-friendly products whenever possible.


Regular facade cleaning not only enhances the appearance of a building but also prevents long-term damage caused by pollutants, mold growth, or weathering. It is especially important in urban environments where buildings are exposed to pollution and environmental factors that contribute to soiling and deterioration.

Sealing of Facades

So when it comes to sealing, we have two systems to offer you.

  1. To seal the facade with our high end product that has a recoat system of 10 years. We would highly recommend considering sealing the facade following treatment because algae need two elements moisture & shade and with your facade being sealed the water will bead off your facade, prolonging algae returning. This will also protect the facade from freeze-thaw action in winter which can crack your facade surface and cause a lot of damage overtime.


  1.  The second system we have to offer you is a sealer that has a five year recoat system for tighter budgets.


All our sealers are permeable, transparent and impregnate the surface unlike sacrificial sealers which blister & crack with the heat of the sun.

Please see in the video where dry brick square appears even when the wall is wet. This is the importance of sealing facades to stop water damages.
