The Importance of Exterior Building Cleaning

Buildings and structures accumulate dirt particles from air pollution, algae, lichen and bird droppings which look unsightly. People underestimate the importance of a well-kept building; as well as giving a poor impression to potential clients, suppliers and your staff, the contamination can damage the fabric of the building meaning that your building will depreciate significantly, if left untouched.

It costs nothing to call on the advice of a reputable Exterior Building Cleaning Company, you can then decide what steps and when you want to take them.

To clean a building correctly, without causing damage, requires specialist knowledge and trained technicians who know exactly how to use the cleaning equipment and the appropriate products to be applied.

Be sure to engage a company who use biodegradable cleaning products, this should be specified on the JMS, with COSHH sheets being supplied to you. This is essential to ensure that you have covered yourselves for any Health & Safety matters.

How will you benefit from calling in APT?

Different areas of the exterior of your building will need different cleaning treatments, depending on the access, contamination and substrate.

The exterior of a building can be made up of many different fabrics and each requires a unique treatment. For example; a heritage building with a stone substrate will require a holistic approach, usually, Soda Blasting, which is a sensitive cleaning process which has been approved by the historic environment services and will not harm the substrate of your building. 

Whereas, Render and K Render surfaces, will require a low-pressure steam cleaning, using specified products. Again, be sure to check the cleaning process, so not to void your warranty.

For high rise exterior building cleaning APT use our high level cleaning team, who are approved and certified by IPAF and PASMA. For the way out of reach we use our IRATA trained rope access teams.

Why DIY Exterior Building Cleaning is not a Good Idea

Using out your own staff and hiring in high-pressure jet washers to clean the exterior of your building façade is a false economy. More damage can be done to the substrate of your building by using untrained staff than its worth. Blasting the contamination off will do as much damage, if not more, than leaving the building to deteriorate naturally. 

Using a high pressure washer to remove any soiling can also cause further damage to weakened surfaces and create microscopic damage to sound surfaces. This leaves the buildings facade vulnerable to further environmental damage unless repairs are made. Please do not underestimate how quickly a buildings exterior can deteriorate.

You also have the hassle of doing all the research, buying in the right chemicals, hiring the right equipment that will allow them to access the highest parts of the building. There is also the issue of the associated Health and Safety practices that should and need be in place for any exterior building cleaning. Hiring in a competent commercial exterior building cleaning company will save you time, money and hassle.

Cladding Cleaning - Brick & Stone


Exterior building cleaning refers to the professional cleaning and maintenance of the outer surfaces of buildings, including walls, windows, roofs, and facades. It involves the removal of dirt, stains, mold, mildew, and other contaminants to enhance the appearance and longevity of the building.

We utilise various methods depending on the building’s material and condition. These methods may include pressure washing, soft washing, window cleaning, gutter cleaning, and specialised techniques for delicate surfaces like glass or historic structures. Our trained professionals use industry-approved equipment and eco-friendly cleaning solutions.

The frequency of exterior building cleaning depends on factors such as location, environmental conditions, building type, and personal preferences. Generally, it is recommended to schedule regular cleaning services on an annual or biannual basis to maintain the building’s appearance, prevent damage, and minimise the buildup of dirt and contaminants.

Yes, our exterior building cleaning services prioritize environmental sustainability. We use eco-friendly cleaning products that are biodegradable and safe for plants, animals, and humans. Additionally, we employ water conservation practices and comply with local regulations to minimise our environmental impact.


Regular exterior building cleaning not only enhances the building’s aesthetic appeal but also helps protect it from premature deterioration. By removing dirt, debris, pollutants, and biological growth, we prevent the buildup of damaging substances that can compromise the building’s structure, surfaces, and finishes.

This proactive maintenance approach can extend the lifespan of the building and potentially save on costly repairs in the long run.
