✅
1. Prevents long-term damage
Algae, moss, mould, and dirt can hold moisture against the wall. Over time, this can:
- weaken the render
- cause cracks
- lead to damp issues inside the house
Regular cleaning removes these before they become a problem.
✅
2. Keeps the home looking fresh
Render stains easily, especially light-coloured render. Cleaning restores the original colour and brightness, improving kerb appeal.
✅
3. Protects property value
A visibly dirty or algae-covered exterior reduces perceived value. Clean render signals that the home is well-maintained.
✅
4. Extends the life of the render
Keeping bio-growth and pollutants off the surface reduces wear, meaning the render lasts longer and you delay needing costly repairs or re-rendering.
