Why render goes dull
Render is a textured surface, which makes it good at holding on to dirt. Rain run-off, damp and shade encourage algae, which shows up as green, grey or black patches, usually first on the sides of the house that see the least sun.
Dark streaks below windows and along the base of walls are common too. They are easy to ignore until you compare them with a freshly cleaned patch.
Render is often porous, so growth can take hold in the surface rather than just sitting on top. That is one reason a quick rinse rarely shifts it, and why a proper softwash treatment is the better route.
Why we softwash it
A jet wash can damage render. Water at high pressure can strip the surface, push water into places it should not go and leave an uneven finish. So render is softwashed instead, a low-pressure treatment that lifts the growth and staining without harming the surface underneath.
This is cleaning, not repainting. The aim is to restore the colour the render already has, so it looks the way it did when it was new.
Walls we can treat
Render is not the only wall surface that benefits. Softwash also suits other walls where algae has taken hold. The online quote asks how many walls you want treated, so you can start with the worst one or do the lot.
Walls that have gone green below a leaking gutter or downpipe are worth a mention when you get in touch. Cleaning the wall will help the look, but it is worth knowing about the cause too.
- Rendered house walls, one wall or all four
- Garden and boundary walls
- Extensions and garages
- Commercial frontages
Make it a full exterior refresh
Render rarely looks tired on its own. If the walls are green, the roof, gutters, windows and drive probably are too. We cover all of them, so you can tackle the lot in one go and get a consistent result.
Fascias and soffits can be cleaned down at the same time. They frame the whole house, and white plastic that has gone grey makes clean render look worse.
