The modern rendered homes around Middlebrook and the pebbledashed inter-war semis are prime targets for algae and that dull green-grey film, thanks to Horwich's exposed, damp position under the moor. Render cannot take high pressure, so we soft wash it with the right chemistry to lift the growth and brighten the wall without cracking the coating or forcing water behind it.

Render softwashing across Horwich
Horwich sits directly beneath Rivington Pike and Winter Hill and gets more rain and damp off the moor than the lower parts of Bolton. That constant moisture, on top of the porous local gritstone, is why north-facing roofs, shaded stone fronts and rendered gables in Horwich grow moss and algae faster than most of Greater Manchester.
Horwich grew up around the railway Loco Works, so much of the older town is tight Pennine gritstone terracing that climbs the slope towards the moor. That quarried stone is porous and textured, holding damp and greening quickly, while the large modern estates around Middlebrook are dominated by silicone and painted render. A single street can shift from delicate stone frontages to hard block paving, so the method has to change house by house.
The Horwich homes we clean most
Gritstone terraces built for the old Loco Works
stone-fronted Victorian semis on the hillside streets
inter-war brick and pebbledash semis
modern rendered new-builds around Middlebrook
larger detached houses on the moorland fringe towards Rivington
What we usually find on Horwich render
Green and grey algae staining on north and west-facing render
red and black organic spotting on textured pebbledash
streaking and run-off marks below sills, gutters and overflow pipes
general dulling and discolouration on modern silicone render
A proper softwash kills the algae at the root, so a K Rend or silicone wall in Horwich stays clean far longer than a quick pressure wash ever would.

What is softwashing and how is it different from pressure washing?
Softwashing uses low-pressure water with specialist solutions to remove algae, moss, mould and lichen without the force that can damage delicate surfaces. It kills growth at the root, so the clean lasts longer than pressure washing alone.
Is softwashing safe for all surfaces?
It's one of the safest methods available, ideal for silicone and Monocouche render, K-Rend, painted walls, cladding, uPVC, roof tiles and pebbledash. We match the solution, dwell time and pressure to each surface.
How long do the results last?
On average 12 to 24 months depending on the surroundings, because softwashing kills the growth at the root rather than just rinsing it off. Shaded, damp or tree-covered walls may regrow sooner.
Can softwashing remove red, green or black staining?
Yes. Softwashing targets and kills the algae, moss and lichen behind red, green and black staining on render, brick and stone, with repeat treatments for especially stubborn marks.
Will it affect nearby plants or grass?
We dampen surrounding greenery before and rinse it after, use biodegradable solutions, and shield delicate planting where needed, so your garden is protected.
