Brick buildings are one of the most iconic features of South London — from Victorian terraces in Clapham and Brixton to period properties in Dulwich, Camberwell, and Tooting. Over time, brickwork naturally becomes stained by pollution, moss, algae, paint splashes, and years of environmental exposure. When property owners want these surfaces restored without damaging the brick, DOFF Steam Cleaning is the number-one recommended method.

At Brick Cleaning South London, we specialise in DOFF cleaning for all types of masonry. In this blog, we explain how DOFF works, why it’s superior to pressure washing, and why it’s the safest choice for London’s older brick buildings.

What Is DOFF Steam Cleaning?

DOFF is a specialist brick-cleaning system developed by Stonehealth. It uses super-heated steam (up to 150°C) to remove dirt, biological growth, paint residue, and grime — all while using very low pressure.

The system works by:

  • Heating water to very high temperatures

  • Releasing steam through a fine precision nozzle

  • Breaking down organic staining instantly

  • Evaporating moisture quickly to avoid water absorption

Because it relies on heat rather than force, DOFF cleaning is ideal for fragile, historic, or porous brickwork.

Why DOFF Is the Best Brick Cleaning Method for South London Homes

South London has thousands of Victorian and Edwardian homes built with soft, absorbent clay bricks. These structures are easily damaged by harsh pressure washing or chemicals.

1. Gentle on Brickwork

Unlike high-pressure jet washing:

  • No risk of cracking the face of the brick

  • No erosion of pointing

  • No water saturation

  • No long-term structural damage

This is why DOFF is approved by:

  • English Heritage

  • Historic England

  • Local London councils for conservation areas

2. Removes Stubborn Biological Growth

South London properties often develop:

  • Black and green algae

  • Moss

  • Lichens

  • Pollution soot

  • General weather staining

DOFF’s high temperature kills spores instantly, meaning the surface stays cleaner for longer.

3. Eco-Friendly Cleaning

DOFF cleaning is chemical-free unless absolutely necessary.
 It uses only water and heat, making it safe for:

  • Family homes

  • Commercial properties

  • Schools

  • Public buildings

  • Conservation zones

4. Perfect for Paint & Graffiti Softening

DOFF softens:

  • Old paint layers

  • Graffiti tags

  • Coatings and residues

  • Airborne pollutants

This makes it an excellent pre-treatment before repainting or full brick restoration.

Common Problems DOFF Can Remove

Our DOFF cleaning service in South London can tackle:

✔ Smoke and pollution stains
 ✔ Algae and moss
 ✔ Bird fouling
 ✔ Efflorescence
 ✔ Paint and coating residue

DOFF Cleaning vs Jet Washing — Why It Matters

Many homeowners assume that pressure washing will clean brickwork, but on older London brick buildings, it causes irreversible damage.

Feature DOFF Steam Pressure Washing
Water Pressure Low High
Temperature Up to 150°C Cold
Risk to Brick None High
Suitable for Old Bricks Yes No
Removes Biological Growth Yes Partially
Approved for Listed Buildings Yes No

For Victorian brick especially, DOFF is the only safe method recommended.
