Pressure Washing in Gauteng

Pressure washing uses high-pressure water and suits hard surfaces: concrete, pavers, brick. Soft washing uses low pressure plus a cleaning solution and is the right method for painted render, siding, roofs, and timber, where high pressure would strip paint, gouge wood, or crack tiles. A good pro will recommend soft washing for delicate surfaces without being asked.

Safe at high pressure: concrete, block paving, natural stone (with care), brick in good condition, metal fences and gutter exteriors. Needs low pressure or soft washing: painted surfaces, render, timber decking, vinyl or fibre-cement siding, roofs, and old or repointed brickwork. Never pressure wash: single-glazed windows at close range, electrical fittings, or asbestos-containing materials.

A single driveway or small patio takes 1-3 hours. A full house exterior typically takes half a day to a full day depending on size, number of storeys, and how much pre-treatment the surfaces need. Add drying time of a few hours before you walk on sealed or treated surfaces.

High-pressure washing damages most roof coverings — it strips granules from asphalt shingles, cracks and dislodges tiles, and can force water under the covering. Roof cleaning should be done by soft washing or manual moss removal plus a biocide treatment. If a company proposes blasting your roof at full pressure, choose someone else.

It depends on the municipality's current restriction level. Cape Town's higher restriction levels have banned hosing paved surfaces with potable water, while low-volume high-pressure equipment or non-potable water may still be allowed. Ask the contractor to confirm compliance for your municipality before booking.

Expect roughly R350-R750 per hour for a crew with equipment, R500-R1,800 for a standard driveway, and R1,500-R5,000 for a full house exterior depending on size. Johannesburg and Cape Town sit at the top of the range.
