Render cleaning
Render cleaning & softwashing
Green, red and black staining lifted from rendered walls with a low-pressure softwash, not a pressure washer.
How we do it
Assessment and test area
We identify the render type and condition, the staining, and vulnerable details like vents, trims and plants. A small test patch may be used.
Protection and preparation
We prepare the area and take reasonable steps to protect nearby features, surfaces and planting.
Softwash treatment
A suitable cleaning solution goes on at low pressure and is left to work on algae, dirt and organic staining.
Controlled rinse and finish
The wall is rinsed in a way that suits the render. Deeper staining often keeps lightening after our visit.
What causes staining on render?
Moisture, shade, nearby trees and poor airflow all encourage organic growth. North-facing walls and areas below roof edges, sills or leaking gutters stay damp longer, so algae spreads and airborne dirt sticks to it.
Painting over it may hide the problem for a while, but it doesn't deal with the growth underneath. If the finish is sound, cleaning can restore much of its look without repainting the whole wall.

- Monocouche and K-Rend finishes
- Silicone and coloured render systems
- Pebbledash and textured coatings
- Masonry, walls and exterior steps
Benefits of softwashing
- Cleaner, brighter walls and better kerb appeal
- Targets green, red, black and patchy staining
- Much lower pressure than power washing
- Can delay the need to repaint a sound finish
Render cleaning FAQ
Is softwashing the same as pressure washing?
No. Softwashing relies on a suitable cleaning treatment applied at low pressure rather than the force of the water. It's usually the better choice for render and coated walls.
Will render cleaning remove every mark?
Algae, organic growth and general dirt usually respond well. Rust, paint damage, cracks or permanent discolouration may stay, and we'll tell you before we start.
Can you clean damaged render?
Light weathering is usually fine. Loose, cracked, blown or flaking render may need repairing first, as cleaning can't fix a defect in the wall or coating.
How long will the result last?
It depends on shade, moisture and nearby plants. No wall stays clean for ever, but the treatment helps slow the return of growth compared with washing alone.
