Our Commercial Building Washing

Steps we follow:

  1. The biodegradable detergent is applied to the external surfaces of the house at a low pressure.
  2. The detergent is left for about 10 minutes to neutralise mould and algae and to detach them from the surface. After this time the mould and algae is washed off at a low pressure.
  3. All external windows are brush washed with a pure water system.
  4. We re-check all of our work to make sure it is of the highest quality.


Professional building washing enhances the curb appeal of your commercial property, creates a positive impression on clients and visitors, and helps maintain the structural integrity of the building by removing dirt, mould, and pollutants.

While routine maintenance is beneficial, professional building washing ensures a thorough and efficient cleaning process. Our trained technicians use specialised equipment and solutions to tackle tough stains and contaminants without causing damage to the building.

The frequency of building washing depends on factors such as the location, climate, and the type of pollutants present. Typically, it’s recommended to schedule professional building washing at least once a year to keep your property looking its best.

Absolutely. Our cleaning methods are safe for various exterior surfaces, including brick, concrete, stucco, and metal. We use environmentally friendly solutions and gentle techniques to ensure the longevity of your building’s materials.

We have the equipment and expertise to handle large or high-rise commercial buildings. Our team is experienced in working with various architectural designs and sizes.

In most cases, there’s no need to close your business during building washing. Our team works efficiently to minimise disruptions, and we can schedule the cleaning at a time that is convenient for you, ensuring business operations can continue smoothly.

The duration depends on factors such as the size of the building and the extent of dirt and stains. Most jobs can be completed within a day or over a weekend, allowing your commercial property to maintain its professional appearance without prolonged downtime.
