Walls are one of the most prominent features of any building—yet they’re often the most neglected when it comes to cleaning and maintenance. Over time, external walls accumulate dirt, moss, algae, pollution stains, and biological growth that not only spoil the look of your property but can also compromise its structure. This is where professional wall cleaning services come in.

At APE Cleaning, we provide expert wall and surface cleaning to restore your building’s appearance and protect it from long-term damage. Whether you're managing a residential home, commercial property, or listed building, our specialist techniques remove years of grime safely and efficiently.

Why External Wall Cleaning Is Essential

External walls are constantly exposed to the elements—rain, wind, air pollution, and organic growth like moss or algae. Without regular cleaning, this buildup leads to several issues:

1. Aesthetic Degradation

Dirty, streaked, or stained walls give the impression of poor maintenance and can reduce your property’s curb appeal—especially important if you’re looking to sell or lease.

2. Biological Growth Damage

Moss, algae, and lichen don’t just look unsightly—they retain moisture and slowly break down render, brickwork, and paint. Our moss removal service includes wall cleaning to stop this damage at the source.

3. Health Hazards

Mould and algae on external surfaces can eventually make their way into your building, impacting indoor air quality and posing health risks, particularly to those with allergies or respiratory conditions.

4. Structural Wear

Over time, trapped moisture from biological growth can lead to cracks, flaking render, and damp ingress—especially in older buildings or poorly maintained facades.

Common Contaminants Found on Exterior Walls

Understanding what you’re up against is key to effective wall cleaning. Here are the most common culprits we remove during our cleaning process:

• Moss & Algae: Thrive in damp, shaded areas and create green or black stains.

• Pollution & Soot: Common in urban areas and along busy roads.

• Lichen: Forms persistent, crusty patches on render and stone.

• Efflorescence: White salt deposits caused by moisture movement through brick or concrete.

• Mould & Mildew: Dark patches often found in humid or poorly ventilated areas.

Each of these contaminants requires a different approach, which is why DIY solutions often fall short. That’s where our professional team steps in.

How We Clean Exterior Walls at APE Cleaning

At APE Cleaning, we use industry-approved methods to deliver powerful results without damaging your walls. Our process typically involves:

Initial Assessment

Every property is different. We begin with a site inspection to identify the surface type (e.g., brick, render, stone, cladding) and the level of contamination.

Soft Washing

Using our specialised soft washing system, we apply a biodegradable cleaning solution that kills moss, algae, and lichen at the root. This method is gentle yet highly effective, especially on delicate surfaces like K-Rend or painted brick.

Biocide Treatment

After rinsing the surface, we apply a long-lasting biocide to prevent regrowth. This helps keep your walls cleaner for longer—typically 12 to 18 months.

Rinse and Finishing

A low-pressure rinse removes all residues and leaves your walls looking fresh and revitalised without stripping away paint or damaging render.

Suitable Surfaces for Wall Cleaning

Our wall cleaning services are suitable for a wide range of materials and finishes, including:

• Render (K-Rend, Monocouche)

• Painted masonry

• Brickwork

• Stone facades

• Pebbledash

• Timber cladding

• Metal or composite panels

Whether it’s a modern office block or a heritage building, we adjust our methods to preserve and protect your surfaces.
