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.

I booked Robin after seeing their work on a neighbour’s house. Our render was covered in grime, especially near the trees.
His team cleaned it gently using a softwash method, and it looks like new. They also took time to tidy up properly and explain how to maintain the walls moving forward.

Robin came highly recommended and completely lived up to the hype. Our render hadn’t been cleaned in over a decade and looked tired, dull, and stained.
After the treatment, the house genuinely looked ten years younger. No disruption, no damage, and no pressure washing — just a clever method that worked. Robin also gave us tips for maintaining the results. A really impressive company and a job we’ll absolutely repeat annually now.

Honestly can’t believe the difference. Our house was looking seriously neglected, with render covered in dark staining, especially around the gutters and shaded areas.
Robin Ray Exterior Cleaning came in and completely revitalised it. They used softwash instead of pressure washing, which was perfect for our older render. Everything was done from the ground, no ladders or mess. We’re so happy with the outcome — it’s like the walls were repainted without the cost or effort.

Robin and his team cleaned the render on our large detached house. They worked efficiently and with great care, using the right tools and solutions for the job.
The stains are completely gone, and we’ve already had compliments from neighbours. No fuss, no mess – just excellent results and a very professional service.

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.

The walls of our house were covered in grime, moss and some red algae that just wouldn’t budge with regular cleaning. Robin used his low-pressure system and managed to remove every bit of it without causing damage.
The property looks transformed. We’ve already booked him for future maintenance!

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.

We’d lived with stained render for years thinking the only solution was to repaint. Then we came across Robin Ray Exterior Cleaning and decided to give them a try.
They used a softwashing method that removed years of algae, mould, and black streaks without damaging the surface. It’s honestly like a facelift for the house. We’ve had neighbours ask who did the work. Great value, really efficient, and such a friendly service from start to finish.

We were sceptical at first, having never used a render cleaning service before. But after meeting Robin and hearing about the methods he used, we felt confident to go ahead.
The team removed every trace of algae and grime using softwashing — a low-pressure method that preserved the render but gave amazing results. No mess, no hassle, just a truly professional experience with outstanding results. It’s rare to find a company that genuinely overdelivers like this.

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.

The team were punctual, polite, and worked really efficiently. They gave a clear quote and stuck to it.
Our house is quite large with old render, but they cleaned it all without any mess or disruption. It’s honestly better than I expected.
