Facade Cleaning, Window Washing, Glass Spaces, and Roof Cleaning

We perform professional and highly effective cleaning of outdoor facades, building cladding, windows, glass surfaces, photovoltaic panels, and roofs using demineralized water. We handle washing from the ground and at heights, employing the efficient Puraqleen technology based on demineralized water.

Outdoor Cleaning

We professionally clean all outdoor parts of buildings. We use completely harmless cleaning with demineralized water, where no chemical aggressive substances are used, avoiding damage to cleaned surfaces. Only greasy, oily stains, etc., require pre-cleaning with chemicals. Washing is carried out from the ground, scissor lifts, and with the assistance of rock climbing specialists.

We expertly clean for our clients:

  • Facades
  • Building cladding
  • Windows, shop windows, and glass surfaces
  • Roofs and photovoltaic panels

Puraqleen Technology

We have extensive experience and excellent results using the Puraqleen technology based on demineralized water, which, due to its physical properties, has a high cleaning capability. On the surface, this water mixes with particles of impurities, which are then rinsed away. Even strong pollution such as bird droppings is removed. Demineralized water has an excellent wetting ability. It dries and leaves no streaks or stains, even in direct sunlight. No additional wiping with cloths or other instruments (commonly practiced in conventional washing) is necessary.

The main advantages of our cleaning technology include:

  • Enables high-altitude washing with a range of up to 20 meters from the ground
  • Simple operation with low personnel requirements
  • Chemical substances are rarely needed for cleaning
  • The system is independent of energy and water sources

HGS has been providing us with above-standard services for 14 years. The company HGS acted very actively in the difficult time of covid, or in case of extraordinary cleaning (accidents, reconstruction). I also appreciate the prompt and helpful communication.

What types of outdoor surfaces can you clean?

We specialize in cleaning various outdoor surfaces, including facades, building cladding, windows, shop windows, glass surfaces, roofs and photovoltaic panels. Our goal is to ensure the complete cleanliness of all these surfaces.

What technology is used for cleaning the exterior parts of buildings and what are its advantages?

We use Puraqleen technology based on demineralized water. This method is gentle on surfaces, leaves no streaks or stains, and is effective even against heavy soiling such as bird droppings. Advantages include the ability to wash up to 20 meters from the ground, easy operation with minimal demands on personnel and exceptional use of chemicals.

Are chemicals used when cleaning facades and glass surfaces?

Usually only demineralized water is used in our cleaning. Chemical agents are used only exceptionally and mainly for the removal of specific stains, such as greasy or oil stains, where it is necessary.

What are the options for cleaning high-rise buildings?

We use different techniques for washing at heights - from work from high-lift platforms to the use of mountain climbing specialists. Our Puraqleen technology enables efficient cleaning up to 20 meters directly from the ground.

Do you need access to power and water to perform outdoor cleaning services?

Our system is designed to be independent of an external power and water source. Thanks to this, we are able to perform cleaning efficiently and flexibly in almost any environment.
