Professional Walls & Render Cleaning by Wizard Wash

At Wizard Wash Exterior Cleans, we provide specialist walls and render cleaning services designed to restore the appearance of your property while protecting the surface underneath.

Exterior walls are constantly exposed to the elements. Over time, algae, mould, lichen, pollution, and organic growth build up — particularly on shaded or north-facing elevations. If left untreated, this not only affects kerb appeal but can also lead to moisture retention and long-term surface deterioration.

Exterior Surfaces We Clean

We clean a wide range of exterior wall finishes, including:

Brickwork
Render (monocouche, silicone & traditional render)
Cladding (uPVC, composite & metal)
Painted exterior walls
Stonework and masonry
Pebbledash
K-render and coloured render systems

Each surface is assessed individually to ensure the correct cleaning method and treatments are used.

Why Walls & Render Need Professional Cleaning

Different wall finishes require different approaches. Using the wrong method — especially high pressure — can cause irreversible damage.

Neglected walls and render can suffer from:

Green, red, or black algae staining
Mould growth, particularly on shaded elevations
Moisture being held against the wall surface
Patchy discolouration and uneven appearance
Premature breakdown of render finishes
Reduced property value and kerb appeal

In some cases, persistent damp or mould on internal walls, especially on external-facing bedrooms, can be linked to moisture being trapped on the outside of the building by organic growth.

How Our Wall & Render Cleaning Works

We use a soft washing approach, specifically designed for delicate and modern exterior finishes.

1. Initial Assessment & Surface Evaluation

We begin with a detailed assessment of your wall or render type — including monocouche, silicone render, painted surfaces, brickwork, or stone. This allows us to select the safest and most effective treatment.

2. Specialist Soft Wash Treatment

Using low pressure and professional-grade cleaning solutions, we treat the surface to break down algae, mould, and lichen at the root, rather than just removing surface staining.

3. Gentle Rinse & Controlled Clean

Once contaminants are neutralised, the surface is carefully rinsed to remove loosened growth without forcing water into the wall or damaging the finish.

4. Ongoing Improvement & Protection

Results continue to improve over time as remaining dead growth naturally weathers away. In many cases, walls continue to look cleaner for months after treatment.
