Why render goes green and black in Glasgow's weather
Render soaks up moisture and Glasgow has plenty of it. Walls that stay damp grow a green film of algae, and darker spotting can follow.
It shows first where the wall stays wet or never gets sun. Think north-facing elevations, walls under overflowing gutters, and corners behind planting.
- Green film or patches that sits on the surface of the wall.
- Dark streaks below the gutter line where water has run down the render.
- Grey, dull-looking walls next to cleaner window frames and doors.
- Worst on the shaded side or beside hedges, fences and planting.
Streaks under the roof edge often start with a leaking gutter. If that is the cause, clearing the gutters stops the marks coming back.
Render cleaning by wall finish: roughcast, K Rend and painted render
Render comes in different finishes and its condition matters. We look at the coating and the staining before choosing how to clean it. We will explain whether the finish can be cleaned and what result to expect before we arrange the work.
- Finish and coatingSmooth, textured or coloured: tell us which, and the brand if you know it.
- Condition of the wallCracks, loose patches and flaking paint cannot be cleaned away. We flag them first.
- Care instructionsIf the installer gave you any, pass them on and we will work to them.
- Photos helpA photo of the worst wall lets us judge the staining before we visit.
This is a cleaning service for the existing finish. Applying new render, painting and repairing cracks are separate work and not part of it.
Render cleaning cost in Glasgow: what affects the quote
We do not give one price for every house, because the walls differ. These are the things we ask about.
- Wall areaA bungalow gable and a full detached house are very different jobs.
- HeightTaller walls take longer and may need different access.
- Amount of stainingA light green film is quicker than years of growth.
- AccessNarrow paths, extensions and planting near the wall all change the plan.
Your quote sets out which walls are included. Some marks can remain where the finish has changed or worn, and we will talk that through with you.
Gutter, soffit and cladding cleaning on the same visit
We also do gutter cleaning in Glasgow, so the wall and the gutters above it can be done together.
Render cleaning reviews from Glasgow customers
Booked to have my gutters cleaned. The guys had excellent time keeping, turning up exactly when they said they would.
Had GGS out to clean our gutters, soffits and driveway. The job done has been immaculate and completed so quickly.
Great service. Guys did a job at my work and then I booked them for my own house.
Render cleaning questions, answered
Is render cleaning the same as painting?
No. Cleaning treats dirt and surface growth on the wall you already have. It doesn't add paint, replace render or change the colour.
Do I need to know which render I have?
It helps, but you can still enquire without knowing. Describe the wall, and tell us about any care instructions from the installer or any treatment the wall has had before.
Will cleaning repair cracks or loose render?
No, those are repair jobs. Tell us about them before booking so we can check whether cleaning can go ahead on that wall.
Will every mark come off?
Not always. Where the finish itself has changed or worn, some marks can remain. We explain what result to expect before we arrange the work.
Can you quote for gutters as well?
Yes. Say so when you enquire and we price the gutter clean and the wall clean together. See our gutter cleaning page for how that works.
