Stone, Brickwork, Render, Coating & Paint Removal Cleaning Services

🧱 STONE & MASONRY CLEANING

Using DOFF or ThermaTech, we safely clean:

• 🟢 Algae, moss, lichen and biological growth
• ⚫ Carbon staining, sulphation, pollution
• 🧼 General grime and traffic film

Suitable for:

• Sandstone, limestone, granite, marble, terracotta
• Churches, listed buildings, boundary walls, detailing

Process:

• Site survey and material testing
• Temperature and pressure adjusted for material type
• Cleaned in uniform sections for consistency
• Surfaces dry rapidly, avoiding recontamination

🧱 HISTORIC BRICKWORK CLEANING

Historic bricks are often soft and fragile, needing a sensitive approach.

We clean:

• Handmade and reclaimed brick
• Georgian, Victorian and Edwardian walls
• Flemish bond and heritage chimneys
• Painted or limewashed bricks

Benefits:

• Preserves glaze and natural surface
• Prevents frost spalling and saturation
• Safe for lime mortar

Process:

• Visual assessment and test patch
• DOFF or ThermaTech cleaning under controlled pressure
• Optional salt neutralising treatments
• Repointing advice available post-clean

🎨PAINT REMOVAL – DOFF / THERMATECH & MICROSTRIPPING

Removing paint from historic substrates requires a tailored, expert process. We remove:

• Plasticised masonry paints
• Acrylic, oil-based or lead-based paints
• Limewash and mineral-based paints (with Microstripping)
• Tar, bitumen, resin coatings
• Graffiti and anti-graffiti treatments

How it Works:

1. Assessment – Identify paint type, thickness, adhesion, substrate
2. Steam Cleaning – DOFF/ThermaTech used to gently soften and lift layers
3. Layer-by-layer removal – Multiple passes if needed
4. Microstripping – For mineral or stubborn paints that steam can’t remove
5. Final clean – Neutralise residues, rapid drying

Removal Rates (Guide Only):

• Plasticised paints: 5–10m² per hour
• Thick/multi-layer coatings: 3–5m² per hour

⚠️ Rates exclude setup/breakdown and depend on material, paint type, access, and finish required.

When Steam Isn’t Enough:

Mineral-based paints chemically bond to substrates – for these, we recommend Microstripping (see: Microstripping Paint Removal)

🛡️ COATING REMOVAL (Tars, Sealants & Paints)

Over the years, many buildings have been coated with unsuitable products. These can:

• Trap moisture and cause spalling
• Discolour or degrade unevenly
• Fail and peel unsightly over time

We remove:

• Bitumen, tar, resin-based coatings
• Cementitious and anti-graffiti paints
• Acrylics, elastomeric layers and old weatherproofing

Process:

• Coating ID and patch testing
• DOFF/ThermaTech for soft, degradable coatings
• Microstripping for hard, mineral-based systems
• Neutralisation and breathable surface restoration

🧽 RENDER & CLADDING CLEANING

Restore the appearance of your building’s render or cladding without damage.

We clean:

• Lime render, monocouche, cement render, K-Rend
• Silicone and acrylic finishes
• Powder-coated and composite panels
• Timber and fibre cement cladding

Common Issues:

• Green/black algae, red biofilms
• Pollution staining, organic growth
• Weathering under eaves or downpipes

Why Use Steam?

• Prevents tiger striping and patchy appearance
• Doesn’t degrade colour or texture
• Surface dries fast and resists recontamination
