Breathe New Life Into Your Walls – Professional Render & Exterior Wall Cleaning That Works
The discolouration on rendered walls is typically caused by organic growth, such as algae, lichen, and fungus. While this growth is unsightly, it can also trap moisture against the surface, potentially leading to damp and long-term degradation.
Robin Ray Exterior Cleaning treats the root cause. Our specialised softwashing process safely kills and removes this growth, restoring your property's appearance and protecting your render. The result is a 'like-new' finish, avoiding the need for costly and disruptive redecoration.
Why Exterior Wall Cleaning Is More Than Just Cosmetic
What looks like dirt is actually a living biofilm — colonies of algae, lichen and mould that feed on your rendered or painted walls. Left untreated, these growths can shorten the lifespan of your surfaces and lead to cracks, moisture retention, and even structural damage.
Robin Ray Ltd uses a low-pressure softwash system to eliminate this growth at the root. It’s safer than pressure washing and is recommended by render manufacturers like K Rend and Webber. It can make walls look like new in just one day.

Tailored Cleaning for Every Wall Surface
Render isn’t one-size-fits-all. That’s why we assess every property before cleaning. Whether you have K Rend, monocouche, silicone, cement, painted render, or pebbledash, we choose the safest, most effective method.
We offer several render cleaning options: Instant Clean, Slow Clean, and Clean & Protect, all designed to meet different needs, surface types, and budgets. We can also apply preventative treatments to help your walls stay cleaner for longer. For peace of mind, test patches are available so you know exactly what to expect.
FAQs – Render & Wall Cleaning Explained
What is softwashing?
Softwashing uses specialist solutions with low-pressure water to safely remove algae, lichen, and dirt from walls without surface damage.
Is it better than pressure washing for render?
Yes. Pressure washing can erode render. Softwashing cleans deeply and gently while helping to prevent regrowth.
Do I need to repaint after cleaning?
In most cases, no. Softwashing restores the surface’s appearance. For painted render, cleaning helps ensure any new paint adheres properly.
Are your products safe?
All cleaning products carry some risk. We take full precautions to protect you, your property, and the environment throughout the process.
Do you offer free quotes and surveys?
Absolutely. We provide in-person surveys, free written quotations, and test patches upon request.
Sand & Cement Render Cleaning
Sand and cement render is one of the most common wall finishes but also one of the most prone to algae and weather damage. Its porous surface holds moisture which allows green and black staining to develop over time.
At Robin Ray Exterior Cleaning we use a low pressure softwash system to clean sand and cement render safely. Unlike pressure washing our method removes organic growth and surface grime without eroding the material. The result is an even finish that restores your render’s natural appearance and helps prevent future staining.
Painted Render Cleaning
Painted render needs careful maintenance to stay in good condition. Algae and dirt can grow beneath the paint which leads to bubbling cracking or peeling if not treated correctly. Our painted render cleaning service removes this build up gently before it causes lasting damage.
We use softwashing and eco friendly cleaning products to restore painted surfaces without harming the coating or colour. Cleaning first extends the life of the paintwork and avoids the cost of early repainting which keeps your property looking clean and protected.

Our rendered walls were looking really neglected and I thought we’d have to paint them. But Robin Ray Ltd completely cleaned them using a softwash solution and now they look brand new.
Highly recommend this service – saved us a lot of money.

I’m so impressed with the work Robin and his team did on our rendered property. Years of grime and organic growth were carefully removed using a softwash treatment.
I particularly appreciated that they offered a test patch first so we could see the likely outcome. The result exceeded expectations. The house looks pristine and it’s made a huge difference to the feel of our garden too. Really friendly and respectful team, which made the whole process easy.

Robin Ray Exterior Cleaning did a fantastic job on our render. The walls had gone completely green and had black streaks running down in places.
Robin turned up when he said he would, gave a really clear explanation of what needed doing, and got on with it without any fuss. The finished result blew us away. I’d absolutely recommend this to anyone who wants to restore their house exterior properly.

The results speak for themselves. Our render had years of dirt, black algae and moss that no DIY solution could fix.
Robin and his team cleaned it all off safely and even treated it to prevent regrowth. It’s a huge visual upgrade and saved us a fortune in decorating costs.conti

We had some really unsightly black stains on our back wall and assumed we’d need to repaint. Robin Ray Ltd advised us to try softwashing first, and we’re so glad we did.
The wall came up brilliantly, and we avoided spending hundreds on redecoration. Honest, helpful, and very good at what they do.

We used Robin Ray Ltd for a full render clean on our detached home. The results were superb.
The green algae on our back walls was completely gone, and even the areas under the eaves came up like new. It’s such a relief to have found a company that doesn’t cut corners and genuinely cares about the results they deliver.

Robin Ray Exterior Cleaning delivered fantastic results. The render had built up a layer of dirt and algae and was starting to look really poor.
After a softwash and rinse, the walls were brighter, cleaner, and fresher. Really efficient and pleasant people to deal with.

I contacted Robin because of his experience with softwash cleaning. Our side walls were covered in grime and algae, and other companies had turned us down due to access issues.
Robin’s equipment allowed him to reach every part without hassle. The job was done with care and precision, and the finish exceeded our expectations. We’re very happy with the outcome.

Our rendered bungalow was covered in green algae and black staining — especially on the north-facing side. We wanted a solution that didn’t involve pressure washing and found Robin Ray Exterior Cleaning online.
They responded quickly, explained the softwash process clearly, and gave us a great quote. The results were nothing short of amazing. The render looks almost brand new, and they even tidied up afterwards. It was fast, professional and mess-free. We’ll definitely be using them again.

Our white rendered home had developed black algae streaks and discolouration over the past few years. Robin Ray Ltd came out, offered a free quote, and then softwashed everything with care.
They protected our plants, worked cleanly, and the result was fantastic. Highly recommend them for anyone dealing with long-term staining or discoloured render.

Robin and his team provided a thorough and careful clean of our rendered bungalow. The staining from tree sap and algae is completely gone, and the finish is flawless.
It’s great to see a company so committed to customer service and the job itself. I’d use them again without hesitation.

Really happy with the end result. The render was looking terrible before, and now it’s totally transformed.
Nice to deal with someone who clearly knows what they’re doing.
