Render Cleaning in Beaconsfield – Why Gentle Cleaning Matters

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.
