Render Care by Nautilus
is a specialist render cleaning company based in the South East of England, serving high-end residential properties across Kent, Surrey, East Sussex, West Sussex, and Greater London. Founded by Darran Smith, the company focuses exclusively on the care and preservation of rendered surfaces, particularly those found on luxury detached homes.
Professional Render Cleaning by Design
Unlike general exterior cleaning firms, Render Care by Nautilus offers a highly specialised approach that combines porosity testing, thermal imaging diagnostics, and a proven Soft Wash method (a safe blend of sodium hypochlorite, water, and surfactant). This ensures a thorough clean while maintaining the integrity of the render.
Render Cleaning The Southeasts Premier Homes
The company is known for its invitation-only service model, working only with a limited number of discerning clients who value discretion, premium results, and long-term property care. Each project is tailored to the surface condition and building design, ensuring both aesthetic restoration and protective treatment.
In addition to cleaning, Render Care by Nautilus provides hydrophobic protective coatings with an optional 10-year guarantee and annual check-ups. These services help prevent mould, staining, and biological growth, prolonging the render’s appearance and durability.
The business is committed to professional standards. All technicians are certified, undergo advanced in-house training, and follow strict surface safety protocols — with no use of pressure washing on sensitive render types.
Darran Smith, the founder, is widely regarded as one of the UK’s leading experts in render cleaning and surface care for luxury homes. He is currently producing a comprehensive educational guide on how to safely clean and maintain rendered surfaces.

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.
