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.

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.

Robin was so helpful from the first message. He came out quickly to do a survey, gave us a clear quote, and booked us in for a convenient date.
On the day, the cleaning was quiet and efficient. Our once green walls are now pale cream again. The difference is incredible. You don’t realise how bad it is until it’s clean!

From quote to clean, Robin Ray Ltd was professional, prompt, and courteous. I was concerned about having soft render cleaned, but Robin explained everything in detail and gave me options.
The clean they did was outstanding — years of staining vanished in a few hours, and the house now looks completely different. The fact they worked safely from the ground without ladders was a bonus. Very impressed by the quality and attention to detail.

Robin cleaned the entire exterior of our house, which had been plagued with red and green algae. His knowledge of render surfaces and what cleaning methods to use was impressive.
We were nervous about softwashing at first, but the process was completely safe and surprisingly effective. The transformation was immediate. It felt like we’d just had the house painted. Robin even followed up to check we were happy — and we definitely were!

We were selling our house and wanted to improve kerb appeal. The render was covered in discolouration and algae.
Robin gave a fair quote and explained how softwashing was safer than pressure washing. We booked him in and were stunned by the results. The clean made such a huge visual difference, and we didn’t need to touch up the paint at all. It made the whole property feel lighter and more modern instantly.

Excellent communication from the first enquiry. Robin gave us a clear quote, explained what softwashing involved, and carried out the work with real care.
Our render is now completely clean, and we didn’t have to worry about ladders, mess, or disruption. Really pleased we chose them over a cheaper alternative.

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.

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.

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.

I especially liked that they offered a free quote first and gave us honest advice about what to expect.

You don’t realise how dirty your render is until it’s been cleaned! Robin’s method removed layers of build-up that we thought were permanent.
He worked quietly, carefully, and left no mess behind. He also made sure to avoid harming our plants and patio furniture. It’s nice to have a service where someone actually cares about the little things. A big thanks from us — our house looks brand new again.

We live in an older property with painted render and were worried about potential damage. Robin’s team did a test area first, then cleaned everything using a gentle method.
No damage, no mess – just a great looking house again. I’d definitely trust them with delicate or older walls.

We live near trees so our render gets stained easily. Robin came out and applied a specialist treatment that worked wonders.
He took time to explain the method and even applied a preventative coat to slow regrowth. Excellent service and no damage to our walls.

Our walls had stubborn red and green staining that I thought would never come off. Robin and his team used a softwash solution that brought everything back to life.
They worked carefully and cleaned up afterwards. I’ve already recommended them to two of my neighbours.
