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.

Really happy with the end result. The render was looking terrible before, and now it’s totally transformed.

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.

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.

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 hired Robin Ray Ltd to clean our render after seeing how well they did our neighbour’s property. The transformation was incredible.
The house looks ten times better and the process was clean, efficient, and didn’t involve any pressure damage.

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.

We couldn’t believe the change after just one day. The green and black algae were completely removed, and the walls now look freshly painted.
Robin’s knowledge and care gave us a lot of confidence. Everything was explained thoroughly and we got exactly what was promised. Great work all around.

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.

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.

We have white painted render that had gone green over the years. The softwash service made it look new again.
I especially liked that they offered a free quote first and gave us honest advice about what to expect.

Robin Ray Ltd cleaned the render on our old farmhouse and absolutely nailed it. The mix of biofilm and lichen growth was extensive, and I wasn’t sure it could even be removed.
Robin talked us through the process, offered a test patch, and delivered on every promise. The walls look amazing and we’ve even had estate agents comment on the improvement. It’s the kind of job you don’t realise you need until you’ve had it done.

Robin’s team explained everything upfront, turned up on time, and worked steadily throughout the day. The transformation was honestly amazing.
The house looks freshly painted, and they didn’t need to use any scaffolding or ladders. Very impressed with the whole process.
