A stained wall isn’t always a decorating job waiting to happen. We first consider the render, its condition and what’s causing the marks. Then we explain what cleaning could achieve, including any limits, so you can weigh up the options before committing to repainting or another treatment.
How Render Soft Washing Treats Discolouration
Render cleaning removes dirt and treats unwanted growth on the protective finish covering a building’s exterior walls. If the wall looks grubby all over, ordinary grime, algae and lichen can be hard to tell apart.
They don’t always need the same treatment. Soft washing uses suitable cleaning solutions at low pressure, letting the product tackle the growth instead of trying to force it off with a powerful jet.
We use this approach on suitable rendered surfaces, including K Rend, painted render and pebble or spar-dashed finishes. The existing colour, texture, paint coating and condition all influence the method. Before starting, we’ll explain the proposed treatment and the improvement you’re likely to see. Some results appear gradually as treated growth breaks down, so the time spent cleaning isn’t always the time needed to see the finished result. The aim is to refresh the finish you already have.
What to Know About Cleaning Your Render
Can dirty render be cleaned instead of repainted?
Yes, when the render is sound and the problem is dirt or organic staining, cleaning may be enough to improve its appearance. Through-coloured render contains pigment within the material, so a discoloured surface does not automatically need paint.
Cleaning reveals the existing finish rather than creating a new one. It cannot replace missing material or repair a failing paint coating. Choosing a different colour is also a separate job, and any later repainting needs a coating compatible with the original render.
What causes red, green and black staining on render?
Algae and other organic growth commonly cause these colours on rendered walls, especially where surfaces remain damp. Shaded walls and properties near trees or water can be more susceptible, so one side of a house may look noticeably worse than another.
Colour alone is not a complete diagnosis: airborne dirt and other deposits can also alter the appearance. The location and pattern of the staining help establish what needs treating, rather than assuming every dark mark is the same type of growth.
How do you clean K Rend without damaging the finish?
K Rend should be cleaned using guidance for the particular finish and a treatment suited to the staining. The brand includes several render products, so identifying the actual surface matters before choosing equipment or cleaning solutions.
Controlled washing may be appropriate, but very high pressure can damage the finish. Algae may need a compatible biocide rather than water alone. A small test area can help check suitability. K Rend is not a general name for every textured wall, and one method should not be assumed suitable for all render.
Can black stains be removed from white render?
Black staining caused by organic growth can often be removed with an appropriate render treatment. Heavy contamination may need further treatment rather than a stronger jet, and improvement is not always immediate.
Some marks have a different cause or extend deeper into the surface, particularly where water has repeatedly run down the wall. Those marks may remain partly visible after cleaning. Establishing what caused the discolouration helps distinguish a treatable patch of growth from staining that cannot be expected to disappear completely.
How much does it cost to clean the render on a house?
Render cleaning costs depend on the wall area, access, surface condition and treatment needed. Cleaning one stained gable is a different job from treating every side of a house, while working above an extension may change the access arrangements.
A useful quote identifies the walls included, the proposed method and whether any further treatment is covered. The number of bedrooms alone does not describe the work. Comparing the same areas and treatment stages gives a clearer picture of what each price includes.
How long does a render-cleaning treatment take to show results?
Some changes are visible quickly, while other treatments continue improving the appearance as treated growth breaks down and weathers away. The product, type of staining and amount of growth affect the timescale.
Removing dirt and treating organic growth are not necessarily finished at the same moment. An estimate should distinguish the time spent cleaning the walls from the time needed to see the final result. Heavy staining may need further treatment, so an immediate, uniform colour change should not be assumed.

Cleaning Silicone and Monocouche Render
Two rendered walls can look very similar without being the same material. Silicone render can be a thin decorative coat over a base layer, while monocouche is a thicker, cement-based finish coloured throughout.
Identifying that difference helps guide the cleaning products and application, with the aim of keeping the colour and texture you like while removing the contamination.
When Streaks Keep Returning Below Gutters
If a dark streak keeps appearing below a gutter, there’s more to consider than washing it away. Repeated water flow can encourage growth and leave stubborn marks.
Cleaning deals with the discolouration, but the source of the water needs separate attention. Otherwise, that same strip of wall may keep getting wet long after the surrounding render has dried.

Client Advice
Understand the full cost
Check experience with your type of render
Different render systems and finishes can require different cleaning approaches, so ask whether the provider has experience with the type installed on your property. Explain what you know about the render and ask how its condition will be assessed.
Relevant experience can help the provider select an appropriate cleaning method.
Ask how nearby surfaces will be protected
Rendered walls may be positioned above paving, decking, roofs or other exterior surfaces. Ask how the provider intends to manage cleaning products, water and loosened material around these areas.
Agreeing appropriate precautions beforehand can help establish what preparation and clearing work forms part of the service.
Confirm the expected timescale
Ask how long the render cleaning is expected to take and whether weather conditions could affect the proposed schedule. The size of the property, access requirements and cleaning process may influence the timescale.
Clarifying this beforehand makes it easier to plan around the work and understand how schedule changes will be communicated.
Look for clear communication
Consider whether the provider explains the proposed render cleaning process clearly and answers reasonable questions about methods, products, access and costs. Clear communication can help establish expectations before work begins.
Ask for important details to be recorded in writing where they affect the scope, price or agreed cleaning process.
Understand the payment terms
Confirm when payment is expected and whether the provider requires a deposit before starting the render cleaning. Ask for deposits, staged payments and possible additional charges to be explained clearly.
Reviewing these arrangements alongside the written quotation gives you a fuller understanding of the proposed service and total cost.

The green wall beside the drive used to catch my eye every time I got home. Now I notice the proper colour instead.
Booking was easy, and they checked which areas I wanted included before giving me a price.

The green side of the house is no longer the first thing I notice pulling onto the drive. Worth it for that alone.
Booking was easy enough and nobody tried to persuade us to have the other walls done when they didn't need attention.

Thank you for your patience with my questions about the pebbledash. It's an older house and I'm cautious about having things done to it.
The team inspected the finish before discussing the clean. It looks considerably less tired now, without losing the character I like. I was also grateful that the path was left clean when they finished.

No fuss, just a clear explanation and a fair quote. Ours was a single wall so not a huge job, but it didn't feel rushed.
The lads cleared up before leaving and I didn't have to chase anything.

We were ready to repaint because I genuinely thought the colour had gone wrong. Turns out much of what we were looking at was staining.
Ash assessed the walls and explained what cleaning might achieve before we spent anything. I'm delighted we tried it. The house looks much closer to how it did when we chose the finish, and painting has come off our list for now.

Had ours treated a few weeks ago. Didn't look completely even at first, which they'd warned me about.
The darker patches have continued fading since then and I'm happy with it now. Worth knowing that before you stand outside judging it on the day.

The red staining down the side had been bothering me for ages. It's much less noticeable now and the wall looks closer to the colour we originally chose.
Glad we asked about cleaning before booking a painter.

Used Elephant for a single wall. No need to do the whole house and they didn't try to persuade me otherwise.
They looked at the surface, explained the treatment and gave me a price. I accepted. The result is a cleaner wall with much less staining, which was the aim. Can't comment on how long it'll stay that way yet, but the work and arrangements were fine.

Only wanted the gable treated. They checked it, quoted for it and did it.
No fuss about it being a smaller job. I was given a sensible explanation of what to expect afterwards and the staining has faded well. Nothing left around the house for me to clear away either.

The side of the house looked almost pink in places, which wasn't the colour we'd chosen. It's much closer to the original cream now.
I hadn't realised cleaning could make that much difference. Very pleased we asked before spending money on paint.

My brother passed on the number after having his house done. Ours looks lovely now as well, especially around the entrance.
I keep noticing it when I get home, which is a nice change from mentally adding painting to the jobs list.

We were looking at paint colours before someone suggested cleaning it first. Glad they did!
We actually like the colour we've got, now we can see it properly.

Didn't expect much to happen after they'd packed up, even though they'd explained it. The stubborn patches really did keep fading.
Looking at it now, I'm satisfied with the result. Worth being patient rather than deciding how it looks straight away.

Our render has quite a rough finish and holds onto dirt. I wasn't keen on having someone blast away at it.
They looked at the surface, explained their approach and answered the questions I had about it. The work has freshened the house up considerably. The path below was left clean too, which I appreciated after watching how dirty it became during the job.

Ashley was patient when I asked him to explain the treatment again with my husband present. We'd both been worried about the textured finish.
Once we understood the approach, we were comfortable booking. The wall looks much cleaner and the texture hasn't changed. It was helpful being able to ask without feeling we were holding everything up.
