Pressure Washing Specialist
A pressure washing specialist uses high-pressure water equipment to clean driveways, patios, decking, walls, and other exterior surfaces. They remove years of dirt, algae, moss, and staining to restore surfaces to their original appearance.
What does a pressure washing specialist do?
Pressure washing specialists clean and restore a range of exterior surfaces, including:
- Driveway and patio cleaning (block paving, concrete, stone, tarmac)
- Decking cleaning and treatment
- Render and exterior wall washing (soft washing for delicate surfaces)
- Roof cleaning and moss removal
- Conservatory and glass structure cleaning
- Fence and garden wall cleaning
- Commercial car park and forecourt cleaning
- Post-construction site clean-up
Do pressure washing specialists need qualifications?
Pressure washing is not a regulated trade. However, professional operators invest in commercial-grade equipment (hot and cold water machines, surface cleaners, softwash systems) and understand which pressure levels and techniques are appropriate for different surfaces.
Incorrect pressure washing can damage surfaces — too much pressure on block paving removes jointing sand, high pressure on render can cause water ingress, and aggressive cleaning of natural stone can erode the surface. Professional operators are trained to avoid these issues.
What to look for when hiring a pressure washing specialist
When choosing a pressure washing specialist, consider:
- Commercial-grade equipment — Professional machines deliver consistent results. Avoid operators using domestic pressure washers.
- Surface knowledge — Different surfaces need different pressures and techniques. Ask how they will treat your specific surface.
- Soft washing capability — Delicate surfaces (render, painted walls, roofs) need low-pressure chemical cleaning, not high-pressure blasting.
- Re-sanding service — After cleaning block paving, kiln-dried sand should be brushed into the joints to prevent weed growth and maintain stability.
- Public liability insurance — Pressure washing near windows, cars, and neighbouring properties carries risk. Ensure they are insured.
Frequently Asked Questions
How much does pressure washing cost?
Driveway cleaning costs £2–£4 per square metre. Patio cleaning costs £2–£5 per square metre. A typical driveway (40m²) costs £80–£160. Decking cleaning costs £3–£6 per square metre. Render soft washing costs £3–£6 per square metre. Most specialists have a minimum charge of £80–£150.
How often should I pressure wash my driveway?
Most driveways benefit from annual cleaning, typically in spring. North-facing areas or shaded surfaces may need cleaning twice a year due to faster algae growth. After cleaning, applying a sealant or biocide treatment can extend the time between cleans and inhibit regrowth.
