Overview
Render goes green and blotchy because algae and organic growth sit in the surface. A pressure washer can mark the finish, blow the face off the render and force water into the wall.
We soft wash the wall instead. The treatment is matched to the render, including painted, through-coloured and textured finishes. Where it is the right method, a biocide is applied so the green growth is slower to come back.
What you get
We look at the type of render, how stained it is, and how we can reach it safely. The visit is then kept simple, so you know exactly what is included.

How we help
Render cleaning is the right visit when the walls have gone green, black or patchy. We regularly help customers who are:
Why choose us
Render should come up clean without the finish being damaged. We soft wash the wall and agree the price before the work starts.
The method is matched to the render so the staining lifts without blowing the face off the wall.
Rendered walls for homes, care homes, schools and businesses.
City & Guilds Softwash technicians, with public liability insurance of up to £10 million.
A text the evening before, and a price you already know.
Our process
Tell us about the walls and send a photo if you can. If you are happy with the estimate, you can book from there.
Once agreed, we'll be in touch within 48 hours. You'll get a reminder text the day before, so we have access around the building.
We soft wash the render as agreed and send an invoice after the work, usually by Direct Debit or bank transfer.
Clear pricing
We believe professional render cleaning should be simple, convenient and transparent. With our easy-to-use online quote tool, you can receive an instant, personalised quote in under 60 seconds, with no hidden fees or unexpected surprises.
Simply click ‘Get an Instant Quote’, enter a few details about the walls and receive your price straight away. If you're happy with your quote, you can book your render clean in just a few clicks.
What to avoid
A close jet can blow the face off the wall and force water behind the finish. We soft wash instead.
The staining is often worst higher up, where a ladder wash never quite reaches. We clean the agreed elevations.
Neat bleach can kill plants and mark paths. The treatment stays on the wall, and planting is protected.
You should know the cost, and what is included, before anyone sets up.
Peace of mind
If any part of the agreed render clean is below our usual standard, tell us within 24 hours and we'll come back and put it right, free of charge.
Pristine Clean Exteriors holds public liability insurance of up to £10 million, so the property is covered while the walls are being cleaned.
Areas we cover
We are based in Poole and cover the towns inside this radius, out to Weymouth, Salisbury and west Hampshire.
View areas we coverCommon questions
Not when the method is right. We do not pressure wash the face of the render. The treatment is matched to painted, through-coloured and textured finishes.
Many walls need it every few years. Shaded elevations, and walls under trees, go green sooner. We'll say what we recommend after seeing them.
Not if we can get safely around the building. We'll text the evening before so you know we're coming.
Where it is the right treatment for the render, yes. It helps slow the algae and green growth coming back. If it is not suitable, we'll say so before we start.
The price depends on the size of the walls, the height and how stained they are. You'll get a quote before we start, with no unexpected charge for the area that was agreed.
Light rain will not stop the clean. If the weather is unsafe, or so heavy that the treatment cannot stay on the wall, we'll move the visit.
Yes. Cladding is a separate quote if you want it added. We will not use a render method on a surface it is not suited to.
Tell us within 24 hours and we'll come back and put the agreed area right, free of charge. The work is also covered by public liability insurance of up to £10 million.
