K-Rend, other types of coloured render, and other varieties of render surface are ideally suited to cleaning with softwashing, rather than traditional pressure washing. It is safe, long-lasting, and green.
Render cleaning is a primary offering from Softwashing UK. Especially when contaminated with organic growth.
Render is used across the UK, especially on large modern buildings, but the manufacturers of render recommend that it needs sprucing up from time to time. Softwashingg UK specialise in render cleaning and offer designated render cleaning services for all types of render. If not cleaned regularly to the colour of render will appear to fade. This is because render is likely to become infected with algae, mosses, and lichens that stain and ruin the appearance of a home or commercial building. Many people simply do not know an effective way to remove stains from render. Fortunately Softwashing is a safe and eco friendly way of removing organic matter and atmospheric pollution from exterior render. Finished coloured renders like K-Rend, Moncouche and Weber suffer with algae, bacteria and mildew staining. Weather and pollution can also lead to staining and discolouration. At Softwashing UK we use our low pressure unit to gently clean render surfaces. If render is subjected to a high pressure wash it can cause long term damage, while softwashing will not harm the buildings substrate. A Softwash will will return any render surface cleaned to its natural state, looking freshly painted, thus increasing the buildings kerb appeal and value. We restore these surfaces, cleaning render, to as new conditions safely from the ground in most cases. In fact we can restore any rendered surface including painted render and all pebble & spa dashed finishes.
It is also very likely that your render will look worse on the north and east sides of the building, where there is less natural sunshine. Having studied the science behind building maintenance, we know that most common atmospheric infections leave swathes of render surfaces with widespread green staining. This can be particularly prevalent on buildings in close proximity to water, as humidity feeds building infections, and the cross contamination caused by spores from nearby trees or other large foliage is a helping factor in this. Left untreated, these stains look tremendously unsightly, and they can detract from the appearance of a home or business. The warmer, more humid weather in the UK means that atmospheric growths are thriving, and are growing on render finished facades harder and faster than ever. Trying to remove these organic growths can prove problematic. High pressure washing can cause real damage, and if incorrectly removed the infection will return too soon. With our softwash treatments we apply softwash products, with steam, to both clean the building and eliminate the infection. This ensures the building looks great after cleaning, and keeps its brilliance.
The staining and discolouration of render leads many to think that full re-painting is the solution. This is expensive and completely unnecessary. Red stains on render, and green algae on render, can be cleaned entirelyWhen it is clean, render keeps its colour! Cleaning render is the recommended and more cost effective way to maintain K-Rend surfaces. Until recently however high pressure cleaning was the only option available. Whether using hot or cold water under high pressure, the aggressive technology blasts moisture beneath render’s surface, which means organic growths return shortly after cleaning. In many cases, high pressure cleaning has even blasted render totally off the wall!
Softwashing UK uses gentle, pH neutral products to kill the infection at root, to clean render and remove stains from render. Our low pressure tank system cleanses and replenishes render, restoring it to its natural finish and colour for years to come, without causing damage. The newly painted look of a clean render that has been softwashed typically lasts for longer than render cleaned by old fashioned methods.
Whether you are looking for a K-Rend algae clean, or other render cleaning services, we are able to help. To discuss our render cleaning services please contact Softwashing UK today.
Render is a popular exterior finish used on homes across the UK thanks to its smooth, attractive appearance and weather resistance. However, over time, render walls can become stained and discoloured by algae, moss, lichen, and general grime. That’s where Softwashing UK comes in.
We offer professional render cleaning using specialist soft washing technology — a safer, longer-lasting alternative to pressure washing.
Specialised Soft Wash Technology
Unlike high-pressure cleaning, which can cause cracks or damage to the render surface, our low-pressure soft wash system uses biodegradable cleaning solutions that penetrate deep into the render. This method safely kills algae, moss, and organic growth at the root without harming the render.
Longer-Lasting Results
Our soft washing doesn’t just make your render look clean — it prevents the return of organic growth by eliminating spores and bacteria. This means your walls stay cleaner for longer, reducing the need for frequent treatments.
Moss, Lichen & Algae Control
We don’t just clean — we treat. Our softwash solution includes a biocidal treatment that destroys moss, algae, and lichen at the source, ensuring your render remains clear and protected from recurring growth.

We’ve used Softwashing a number of times over the past few years to clean the exterior of our house, gutters and patio. Every time it has been a fantastic service, always going above and beyond, whether it’s attacking a stubborn rust stain or taking time to explain the process. We have recommended them to friends and neighbours and using them every year is testament to how happy we are with the work they do. Thanks!

The service was great, Gavin arrived on the dot of eight o’clock and he then talked me through the process before starting. He worked diligently using a range of different techniques to address the various issues. At the end the render looked like new! Would definitely recommend and will have them back again when it needs doing again! Peter Grant2025-03-29Trustindex verifies that the original source of the review is Google. As a director of and on behalf of Wardour Court Management Company and residents I wish to record our thanks to Gavin and his team. The property is a sensitive building constructed of Chilmark stone, it had not been cleaned for some time and was looking the worse for wear. They were all extremely efficient and professional as well as very pleasant and easy to talk to despite the difficulties they encountered, which included having to work 17 hours on one of the days. All the residents I have spoken to have expressed how pleased they are with the result, as are the directors of Wardour Court Management Co. We would happily use this company again and are equally happy to recommend them to others. Ann Grant Jewellery2025-03-29Trustindex verifies that the original source of the review is Google. Gavin and his team recently cleaned the Chilmark stone courtyard mews where I live. The stone was in dire need of cleaning and proved to be a very difficult job including one 17 hour day. Despite the difficulties he and his team remained pleasant, friendly and very professional leaving us with what I can only describe as a transformation ... our ugly duckling has become a swan. I can't thank them enough for their dedication and would happily recommend him and his company. City Stays sw Ltd2025-02-05Trustindex verifies that the original source of the review is Google. One of our properties, which is a rental, was a complete eye sore on the exterior surfaces, which needed rectifying before it was able to go back on the rental market. After ringing around different companies, Softwashing UK stood out and understood our requirements. Softwashing UK Soft wash cleaned 15 years' worth of bad organic staining from our K-Rend render, brickwork, and all rain water goods to the property. We honestly could not believe the results that were achieved. The render now looks like the day we had it rendered. On the day of the work ne carried out, the guys turned up on time and carried out the job respectfully and professionally. It's great to see good tradesmen still exist. We highly recommend the soft wash service they offer, and we will be sure to recommend Softwashing UK our friends and family's.
