Render Care
Flawless elegance, quietly lasting. A home that stays pristine — and always earns a second glance.
When should the render be soft washed?
1. Ideally before any mould has been allowed to grow.
2. As soon as you notice any mould growth.
What could happen if I leave organic matter growing on my render?
1. Organic matter is natures way of decomposing which causes something to decay. Render decays very quickly compared to other building materials.
2. The top layer of render can be “eaten away” by the organic matter, you can only see the damage once the organic matter has been carefully soft washed.

I have lots of organic matter growth on my property, what can be done?
1. Arrange to have your render cleaning project undertaken by a soft washing professional who will explain the outcome truthfully.
2. An onsite inspection will help you understand better what outcome you can expect. Spend time with the surveyor walking around and ask questions.
Where should I expect to see decay after a soft wash clean?
1. Common areas which decay first are usually seen at the edges of windowsills. Where water has run down the render and “fed” the organic matter at a 45-degree angle from the edge of the sill. You can see this now as a darker stain on the render. Although soft washing can safely remove the dark organic stain without causing further damage. It may reveal the decomposing of the render which may look slightly different after the render cleaning process has completed. No cleaning method can reverse decomposition.
2. Other areas which may also be affected are usually seen underneath badly fitted coping stones at higher levels. Overflow water pipes which have not been fixed. Full and overflowing gutters and behind down pipes. These areas all allow more rainwater to feed the organic matter growth.
3. Moss and lichen. Once moss and lichen have been allowed to grow, it is likely that you will see evidence of where it has been. This can sometimes be seen as decay and exceptionally light green stains which has dyed the render.
In most cases, the damage is hardly noticeable. Cleaning your render sooner will prevent further issues like cracking or flaking.
What is soft washing and why is it better for render cleaning?
1. Soft washing is the alternative to pressure washing. It uses bio-degradable chemicals which sanitise the surface on which it is sprayed. It uses no harsh pressure which could further decompose the render. The clean lasts longer when compared to any other type of cleaning method.
2. Soft washing is the careful blending of three liquids, water, sodium hypochlorite and soaps. Water at 97%, sodium hypochlorite at 2% and soap at 1% is the most common mix for render cleaning projects.
3. Specialist soft washing equipment is manufactured in the USA and used in the UK by accredited professional soft washing companies.
