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’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.

Fantastic job from start to finish. Our render had black streaks all down the back wall – now completely gone.
I would happily recommend Robin Ray Exterior Cleaning to anyone needing this kind of service.

The team at Robin Ray Exterior Cleaning did an incredible job restoring the render on our Victorian house. We had algae, lichen, and a fair bit of grime that built up over years.
They used softwashing, which was gentle on the old surfaces but highly effective. The place looks fantastic and the walls feel completely refreshed. Definitely a five-star service from a team that clearly knows their stuff.

I didn’t realise how bad the render had got until Robin cleaned it. It looked like a completely different house!
The staining was gone, and the softwash left a really nice even finish. They worked carefully around windows and pipes. Very impressed with the level of service and attention to detail. Worth every penny.

We booked Robin after seeing his work online. The house looked tired, with algae streaks and general dirt all over the render.
He used a low-pressure softwash system that was gentle but incredibly effective. Not only is everything clean, but he also applied a treatment to prevent the growth coming back. Great value for money and you can tell he really knows what he’s doing. Highly recommend this service to anyone with tired-looking render.

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.

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.

I asked for a quote and Robin came out the next day. He talked me through the options and tailored the clean to suit our older render.
The difference is night and day. We saved money on repainting and now the exterior is fresh and bright again. A really worthwhile investment.
Danielle Vickers








Great job from Robin and the team. They cleaned our front and side walls in under a day, using a method that didn’t leave marks or splash mess everywhere.
The house looks years younger now. We’re very pleased with the result.
