Cladding Cleaning in the UK Using Safe Soft Washing Methods
Professional cladding cleaning for commercial and large residential buildings across the UK.
What is Cladding Cleaning?
Cladding cleaning is the professional removal of algae, pollution, carbon deposits and organic staining from external cladding systems using low-pressure cleaning methods that protect surface finishes.
Why low-pressure cleaning is used for cladding
Most cladding systems are not designed to withstand high-pressure washing. Low-pressure cleaning allows contamination to be removed without forcing water behind panels, damaging coatings, or compromising fixings and seals.
- Reduces the risk of water ingress
- Protects factory-applied coatings and finishes
- Avoids surface etching and premature wear
- Suitable for modern architectural cladding systems
What types of cladding can be professionally cleaned?
Most modern cladding systems can be safely cleaned using low-pressure methods, provided the surface type and condition are properly assessed beforehand.
Plastic coated steel cladding
Commonly used on commercial and industrial buildings across the UK. Durable and low maintenance, plastic coated steel can be cleaned to restore appearance without damaging the protective coating.
Powder coated metal cladding
Available in a wide range of colours and finishes. If UV degradation has occurred, the surface may appear dull or faded and restoration rather than cleaning alone may be required.
UPVC cladding systems
Used on both residential and commercial properties. Low-pressure cleaning removes organic staining and atmospheric pollution without marking or distortion.
Architectural façade panels
Modern façade panels require controlled cleaning to protect joints, fixings and surface finishes. Low-pressure methods are essential to avoid water ingress and surface damage.
Our cladding cleaning process
- Initial inspection of the cladding system and surrounding areas
- Assessment of surface condition and contamination type
- Application of a controlled low-pressure cleaning solution
- Appropriate dwell time to break down organic growth and staining
- Careful rinse and surface neutralisation where required
This process is designed to clean effectively while protecting the integrity of the cladding, fixings and surrounding surfaces.
Is cladding cleaning safe?
Yes, when carried out using low-pressure methods. High-pressure washing can damage coatings, force water behind panels and shorten the lifespan of cladding systems. Low-pressure cleaning avoids these risks.
How long do the results last?
Most cladding systems remain clean for 24 to 36 months, depending on building location, exposure to pollution, surrounding vegetation and weather conditions. Buildings near roads, industry or shaded areas may require more frequent maintenance.
Who is cladding cleaning suitable for?
Cladding cleaning is suitable for commercial, industrial and large residential buildings where maintaining appearance, protecting surface finishes and reducing long-term maintenance costs are important.
- Commercial buildings and business parks
- Industrial units and warehouses
- Apartment buildings and managed developments
- Large residential properties with architectural cladding

This page provides a national overview of cladding cleaning methods and best practice. Dedicated regional pages are available for specific locations, while the cleaning process and standards remain consistent across the UK.
How much does cladding cleaning cost?
The cost of cladding cleaning depends on building size, access requirements, cladding type and the level of contamination present. In many cases, accurate estimates can be provided without a site visit using measured data and photographs.
When should cladding be cleaned?
Cladding should be cleaned before staining becomes embedded or surface coatings begin to deteriorate. Regular cleaning helps preserve appearance, extend the lifespan of the cladding system and reduce long-term maintenance costs.

Pressure Washing
When anyone thinks about exterior cladding cleaning the pressure washer always comes to mind first. Although pressure washing can clean many types of cladding it is not always the best choice. Pressure washing can use cold or hot water. The water flow used is important, it could be from fifteen litres per minute to thirty litres per minute, which is a lot of water used during the day.
- Pressure washing cladding gives you a low cost quick clean.
- Pressure Washing uses a LOT of water.
- Pressure Washing does not kill the root of the organic matter therefore it will re-grow quicker and thicker than before.
Soft Washing
Soft washing is the alternative to pressure washing it uses one third the amount of water. It uses safe bio-degradable chemicals to treat the organic matter and leaves surfaces sanitised clean. Re – growth is therefore eliminated although in time NEW GROWTH will occur.
- Soft Washing lasts 2-3 times longer when compared to pressure washing.
- Soft Washing uses quiet battery powered low pressure pumps.
- Soft Washing allows the use of additives to leave the building shiny.
Manual Cleaning/Restoring
When damaged by the suns UV rays, cladding cleaning will still leave the building looking dull and washed out. Therefore, a manual restoration clean is required. Using specialist restoration creams and coatings to bring back the original colour.
- Restoration type cleaning is labour intensive and expensive.
- Not many cleaning companies have the relevant experience to restore natural colours.
- Prevention of UV damage is certainly cheaper than the cure.
Choosing the Right Cleaning Method
When selecting a cladding cleaning contractor, you should consider what cleaning methods they intend to use. Do they have several types of cleaning equipment to remove safely the contaminants affecting your building.
- Plastic Coated Steel: Soft Washing or Pressure Washing for organic matter and grime.
- Weatherboard and Cedar Wood: Soft Washing or manual cleaning to prevent damage.
- Aluminium, Zinc, Copper: Manual restoration style cleaning after gentle soft washing to remove organic matter contamination.
