If you’ve noticed your render looking darker, patchy, or green in places, you’re not alone.
This render clean was carried out in Beaconsfield on a property where organic growth had slowly built up over time.
It hadn’t happened overnight.
It had built up quietly.
That’s usually how it goes.
Why Render Gets Stained
Render staining is normally caused by:
Organic growth (algae, moss spores, lichen)
North-facing damp walls
Shaded areas
Moisture retention
It often starts subtly — small patches, slight darkening — then gradually spreads.
By the time it looks “obvious”, it’s usually been developing for months or even years.
Why You Shouldn’t Pressure Wash Render Aggressively
This is important.
Render is not the same as concrete, bricks or stone.
High pressure can:
Damage the surface
Blow out weak areas
Leave uneven results
Force water into the structure
That’s why I use a gentle softwash process instead.
The Process Used on This Beaconsfield Property
1. Careful assessment of the surface
2. Gentle removal of surface growth
3. Softwash treatment applied
4. Rinse and final inspection
No aggressive blasting. No rushed job. Just careful, methodical cleaning.
The Result
Even colour restored
Organic staining removed
Property appearance significantly improved
No surface damage
Render cleaning is about patience and the right method — not force.
When Should Render Be Cleaned?
If you’re seeing:
Green staining
Black streaking
Patchy discolouration
Persistent damp-looking areas
It’s usually worth dealing with it before the surface deteriorates further.
