How Long Does Pressure Washing Take? A UK Homeowner's Guide

Here's a realistic breakdown of how long professional pressure washing takes for common domestic surfaces:

• Standard driveway (single car, block paving): 1.5–2.5 hours
• Double driveway (block paving or tarmac): 2.5–4 hours
• Patio (up to 30m²): 1–2 hours
• Patio (30–60m²): 2–3.5 hours
• Garden path: 30–60 minutes
• Decking (up to 20m²): 1–1.5 hours
• Full property exterior: 4–8 hours (depending on size and condition)

These times assume professional-grade equipment and experienced operators. DIY pressure washers typically take 50–100% longer for the same result.

Several factors can extend the time needed:

• Heavy algae or moss thick biological growth needs pre-treatment with a biocide before pressure washing for best results. This may add 30–60 minutes (or require a return visit once the biocide has worked).
• Deeply ingrained oil stains on driveways these often need a degreaser application and dwell time before washing.
• Surface age and condition older, heavily contaminated surfaces need lower pressure and more passes to avoid damage.
• Access constraints narrow passages, steps, or tight corners all slow progress.
• Weather cold weather affects chemical dwell times; very windy conditions affect overspray management.

Yes for most external pressure washing jobs, you don't need to be home (though it's helpful for the first visit). The team works entirely outside and won't need access to the interior of your property. We do ask that you move any vehicles, garden furniture, or potted plants from the area being cleaned beforehand.

We'll knock on arrival and give you a heads up when we're done so you can inspect the result before we leave. If anything doesn't meet your expectations, we'll address it on the spot.

Hiring a professional pressure washing team is significantly faster than DIY not just because of better equipment, but because of experience. A team that cleans driveways every day knows exactly how to approach different surface types, contamination levels, and edge details.

A typical homeowner pressure washing their own driveway for the first time might spend 4–5 hours on a job a professional team completes in 2. Factor in equipment hire, transport, and the learning curve, and professional cleaning often makes more economic sense.
