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.
Why Choose Us
Experienced Advice, Without the Hard Sell
You don’t need to know the name of every render treatment to make a sensible choice.
With over 25 years in the trade, we’ll explain what we propose, why it suits your walls and the change you’re likely to see. The advice stays practical, without promising that every mark will disappear.
Soft Washing With Workmanship Cover
Your walls deserve more thought than simply turning up the pressure. We use soft washing with products selected for the surface, keeping the existing finish in mind throughout the work.
Public liability insurance and a 12-month workmanship warranty give you further reassurance about the people you’re trusting with your home.

A single stained gable is as welcome as a whole rendered house. We’ll explain the work and give you a competitive quote, without making the job bigger than it needs to be.
We also match official like-for-like quotes, so you can compare the proposed treatment as well as the price.

Client Advice
Ask how nearby surfaces will be protected
Confirm what areas are included
Make sure the quotation clearly identifies which rendered walls and sections of the property will be cleaned. Ask about difficult-to-access areas, extensions, boundary walls or other rendered surfaces if these are relevant.
Agreeing the scope beforehand helps ensure that you and the provider have the same expectations when work begins.
Check recent and relevant feedback
When reviewing customer feedback, look particularly for recent comments relating to render cleaning or comparable exterior cleaning work. Feedback may provide useful context about communication, organisation and tidiness, but it cannot guarantee your own outcome.
Consider it alongside relevant experience, the written quotation and the provider's proposed cleaning method.
Confirm suitable insurance cover
Ask whether the exterior cleaner holds suitable public liability insurance for render cleaning work. Insurance does not demonstrate the quality of the service, but appropriate cover may provide protection if accidental damage occurs.
Ask what the policy covers and whether evidence can be provided if reasonably requested.
Ask about access equipment
Render cleaning may involve working above ground level, depending on the height and design of the property. Ask what access equipment the provider expects to use and how the work will be organised.
Understanding the proposed access arrangements also helps you check whether their cost is included in the quotation.
Discuss staining before work begins
Point out areas of discolouration, organic growth or other staining when requesting a quotation. Ask what improvement the provider reasonably expects from the proposed cleaning method and whether any areas require separate treatment.
Discussing likely results beforehand can help establish realistic expectations rather than assuming every mark will disappear completely.

Please pass on my thanks. I was nervous about having work done while on my own, but the men were easy to talk to and let me know what was happening.
The outside looks lovely now. I'd been apologising for the state of it whenever family visited, probably unnecessarily, but it's nice not to feel I need to do that any more.

I was worried about our textured finish being damaged. Ashley looked at it first and explained the low-pressure approach in terms I could understand.
That reassured me enough to book. The house looks fresher now, and the texture that I like is still there.

Thank you for taking such care with our house. The pebbledash looks much fresher and the men were very polite.
I appreciated being able to come out and ask questions without feeling in the way.

Had used them previously, so rang again when the side wall needed attention. Arranging it was straightforward.
They assessed the staining, explained the work and gave me a price I was happy with. The treatment has improved the wall without us having to do anything further. I've been advised to keep an eye on that shaded area, which seems sensible enough.

The front of the house looks brighter without us having changed the colour. Exactly what I wanted, really.
Happy with how the job was handled.

Our pebbledash has always been quite pale, so the dark staining really showed. I wasn't expecting every trace to disappear, but the improvement is better than I'd hoped.
Thank you for taking care with it.

Ashley was very patient with my questions. I hadn't realised cleaning might be an option before painting.

Wanted the house freshened up before family visited. It had been one of those things on the list for months.
Easy enough to organise once I actually made the enquiry. They checked the walls and explained the likely result. Looks much better now, and we didn't end up spending the weekend clearing up after the work.

They explained that some improvement would be gradual. Glad I knew that, because the wall looks better now than it did straight after the visit.

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.

I'd assumed the black streak would just wash off with the rest, but Ashley pointed out that it had been getting wet repeatedly beneath a gutter. We had that attended to separately.
The cleaning has reduced the mark a lot, though you can still find it if you know where to look. Glad the cause was raised beforehand. Otherwise I'd probably have been wondering why the same bit started looking grubby again.

We nearly had the house painted before somebody suggested getting the render assessed. Glad we listened.
Cleaning has made enough difference that we're keeping the existing finish, which I always liked underneath the staining.

The wall had a stubborn line beneath a gutter we'd recently had repaired. Ash was honest that cleaning might leave some trace.
It has, but it's much fainter and the surrounding render looks good. I knew what I was agreeing to and I'm satisfied with the result.

I wanted the actual render identified rather than everybody simply calling it K Rend. Elephant checked before recommending the method.
That attention to the surface gave me confidence to book, and the clean has improved its appearance without changing the texture we like.

was a bit nervous about having the render cleaned but they talked me through it. So pleased I went ahead, the front looks much fresher
