Render Cleaning London

Low-pressure washing for a high-impact finish

Render has become popular as an exterior surface on various buildings. This is for a number of reasons, including the range of finishes – including smooth, textured, brick effect and more – available with render, which also does not need painting after application.

However, despite common claims that render is “maintenance-free”, its exposed nature means that it can actually collect dirt and organic matter, such as moss or algae, as the years pass. Subsequently, the render can discolour, turning red or even green.  

All the same, though, the worse-for-wear render should not be subjected to high-pressure washing, as this can damage the render. Fortunately, we have professionals who can use specialist products and equipment to apply the low-pressure washing your render needs.

Soft-washing render

As your render is increasingly infected by the likes of moss and algae and has the unsightly staining to show for it, you could be at a loss as to how to treat the problem. However, our experts can use the technique of soft washing to rid your render of organic matter and atmospheric pollution in a safe and environmentally-friendly way.

This approach works on a wide range of renders, including K Rend, Moncouche and Weber renders, which can be prone to bacteria and mildew stains. The cleaning solution will be applied at a low pressure to ensure that render surfaces are gently cleaned without the building's substrate incurring damage. A soft wash will leave the render looking as though it has been freshly applied.

ThermaTech magic

One undoubtedly valuable weapon in our render-cleaning arsenal is the ThermaTech super-heated water system. This piece of equipment is suited to various cleaning tasks, and we can adjust our 110v ThermaTech system's pressure from 140 right down to 20 bar - and lower still through using pressure-reducing guns. This makes the technology ideal for gently cleaning delicate substrates.

Whether the render you would like us to clean is part of a domestic property, school, hotel, office or any other building in London, we can soon be there with our ThermaTech equipment. The machine can be adjusted to heat the contained liquid as much as 150°C, and the spores responsible for that ugly staining will be killed as the liquid is sprayed onto the surface and takes effect.

Unfortunately not. The problem is that, while this approach to cleaning render will wear down its surface, it won't completely eradicate spores. As a result, those left will simply re-grow even thicker - and more quickly - than before. Soft washing, however, will get rid of even micro-organic spores, meaning that the surface won't need re-cleaning for quite a while.
This is because soft washing kills infections at the root through the use of gentle, pH neutral products. Our ThermaTech cleaning system helps in this task, as it allows us to minimise our use of chemicals in the cleaning process. The technology also makes milder agents more effective, enabling us to clean renders gently but thoroughly.
Many people assume so, but you should keep in mind that it would be completely unnecessary. This is because red and green stains alike can be cleaned away entirely, without leaving any trace of their former existence. A well-cleaned render will preserve its colour, saving you from needing to find just the right hue of paint for re-painting work, which would not be as cost-effective as cleaning anyway.
Those sides are likely to be the north and east sides, as these will not be exposed to quite as much natural sunshine as other sides. Green staining can be particularly prevalent on areas near water, as increased humidity can lead to more infections. The problem can be exacerbated as spores arrive from nearby large foliage like trees.
When we visit your London property, we will carefully assess it before giving it a test sample clean. That way, you can see for yourself how the cleaned surface looks. If you like the result, you can give us the go-ahead to clean the rest of the surface, all without disrupting your home or work life.
