Render cleaning with a soft wash, never a pressure lance.
Green and black staining on render is biological growth, not dirt. We treat it at low pressure with a solution that kills it at the root, so the finish comes back without the surface being thinned or opened up.

Why we do not pressure wash render
A pressure lance makes render look clean quickly, but it can thin or open the surface. That leads to a patchy appearance and faster regrowth, and on through-coloured render it is the usual cause of colour loss.
A soft wash works the other way round: the solution does the work, not the force. It breaks down the biological film that gives render its dull green-black cast. If you want the detail first, read our render cleaning guide or the render cleaning cost guide.
How a render clean works
A careful, methodical approach designed to protect your roof and your property.
Check the render
We look at the render system and the staining so the treatment suits the surface.
Protect and apply
Planting and glazing are protected, then the soft wash is applied evenly at low pressure.
Rinse and clear down
The surface is rinsed where needed and the area is left tidy.
Frequently asked
Will cleaning remove the colour from my monocouche render?
Not with low-pressure chemical cleaning. Colour loss on through-coloured render is almost always caused by a pressure lance thinning the surface.
Is a soft wash safe on silicone and thin-coat render?
Correctly applied, yes. Soft washing is the recommended approach for modern thin-coat and silicone render precisely because pressure washing damages them.
Why is a pressure-wash quote cheaper?
The method is faster. It looks clean sooner but risks thinning or opening the render, which leads to a patchy finish and faster regrowth. We do not use pressure on render.
Can you clean the roof at the same visit?
Yes. We also clean roofs by hand and apply biocide treatments, so render and roof can be quoted together.
