Render Softwashing in Birmingham
Black streaks, green algae and red film lifted from render and painted walls with a gentle, low-pressure treatment that keeps working for months — and never damages the surface.
Render should never be blasted with a high-pressure washer — it cracks the surface and forces water behind it. Softwashing is the correct method: a specialist biocide is applied at low pressure to kill the algae, lichen and bacteria at the root. The wall then continues to clean and brighten for weeks as the treatment works.
It's safe for silicone, acrylic and traditional render, pebbledash, cladding and painted masonry.

Questions, answered
Is softwashing safe for render?
Yes — it's the recommended method. Low pressure plus a biocide kills the algae without the cracking and water ingress that high-pressure washing causes on render.
How long until the render looks clean?
Some lift is immediate, but softwashing keeps working — most walls visibly brighten over the following one to three weeks as the treatment kills off the growth.
How much does render cleaning cost?
A front elevation starts at £250 and a whole property at £450, depending on size and access. You'll get a fixed quote first.
How long does it stay clean?
Typically one to three years depending on shade, trees and damp. We can set up a maintenance visit to keep it looking new.
