Our 3-Step Wall Cleaning Method

Bio-Treatment Application

A biodegradable pre-treatment is applied to break down mould, algae, lichen, and oily soot before any pressure touches the wall.

Calibrated Pressure Wash

We wash at concrete-safe pressure, lifting grime out of the wall’s texture without etching, pitting, or stripping the surface.

Post-Cleaning Site Rinse

Paving, driveways, and adjacent garden beds are thoroughly rinsed so your property is left spotless when we leave.

Local Conditions

Property Challenges in Johannesburg

Johannesburg’s urban forest, heavy traffic, and Highveld storms create specific challenges for exterior property surfaces.

Urban Forest Shade & Moss. Johannesburg is often called one of the world’s largest man-made forests. Suburbs like Parkhurst, Parktown, and Melville sit under dense canopies that keep walls shaded and damp, letting moss, lichen, and black mold flourish.

City Traffic Soot. Arterial roads such as Jan Smuts Avenue, Oxford Road, and the M1 carry constant traffic. Exhaust soot and road grime settle on street-facing boundary walls as a sticky grey film.

Highveld Storm Mud Splash. Sudden summer downpours splash red soil onto the base of boundary walls. Baked on by the afternoon sun, these tide marks become stubborn stains that regular hosing cannot remove.

The good news? It all washes off. Get a free quote →

Johannesburg FAQs

Got questions? Here are answers to the most common questions we receive from our Johannesburg clients.

Yes. Older walls in heritage suburbs need a gentler approach. We adjust pressure and use soft-wash pre-treatments so aged concrete and painted finishes are cleaned without damage.

We require access to an outdoor tap to feed our cleaning equipment. However, our pressure washers are powered by quiet petrol engines, meaning we are self-sufficient for electricity.

Yes. We use premium, biodegradable cleaning agents that break down rapidly. They dissolve mold, algae, and grime effectively but are 100% safe for Johannesburg's gardens, lawns, and household pets.
