Pressure washing quotes can look wildly different from one company to the next. One says your driveway is a quick job. Another quote doubles for what sounds like the same thing. Both can be right, and both can be wrong.
We pressure wash driveways, patios, paths and walls across Harrow, Pinner, Stanmore and North West London every week. This guide covers what drives the cost, what a fair quote should include, and how to spot a quote that’s too good to be true.
What Affects the Cost of Pressure Washing?
The price moves up or down depending on a handful of things.
The Size of the Area
More surface means more time, more water and more cleaning product. A small patio is a very different job to a double driveway with a path and side passage.
The Type of Surface
Block paving, concrete, tarmac, natural stone and decking all need different pressure and technique. Block paving usually takes longer because of the joints. Natural stone needs a gentler approach, which takes more care and more time.
How Dirty It Is
A surface with a light layer of algae is a quicker job than one with years of moss, ground in grime and oil staining. Heavily soiled areas can need a second pass or a pretreatment, and that affects the price.
Access and Water Supply
Easy access and an outdoor tap keep things simple. Tight side passages, steps or no water supply on site can add time to the job.
Where You Live
London and the South East usually sit at the higher end of UK pricing. That reflects fuel, insurance, equipment and labour costs here, not padding on the quote.

What About London?
MyJobQuote puts average London labour at £70 to £90 an hour, about a third higher than the UK average. So expect Harrow and North West London quotes to sit at the upper end of these ranges.
For a closer look at the work involved on each surface, see our pressure washing service or our guides to driveway and patio cleaning.
What Should a Fair Quote Include?
A proper pressure washing quote should be fixed before any work starts, and should make clear what you’re getting. Look for:
- The right equipment for the surface, such as a rotary surface cleaner on block paving
- Pressure adjusted to the material, not one setting for everything
- Treatment for oil stains where needed
- Before and after photos
- Public liability insurance confirmed
Our driveway cleaning service covers all of this as standard.

Red Flags in a Pressure Washing Quote
Most pressure washing companies are honest. A few give the rest a bad name. Watch out for:
- A very low price with no detail on what’s included
- No mention of the equipment or technique they’ll use
- No public liability insurance
- Cash only with no invoice
- Pressure to book on the spot for a discount
Is Pressure Washing Worth the Cost?
For most homes, yes. A professional clean does more than make the surface look better:
- It removes the algae and moss that make paths and patios slippery
- It lifts kerb appeal without the cost of replacing or resurfacing
- Done properly, it protects the surface rather than wearing it down
Done badly, it can cost you more. Blasted joints, etched stone and streaky finishes are expensive to put right. That’s why the cheapest quote isn’t always the best value.
How to Get a Fair Quote
Ask every company the same questions so you can compare like for like:
- Is the price fixed, or can it change on the day?
- What equipment and pressure will you use on my surface?
- Does the price include oil stain treatment if needed?
- Will I get before and after photos?
- Are you fully insured?
The Bottom Line
Pressure washing costs depend on the area, the surface, how dirty it is, access, and where you live. A standard driveway typically lands between £150 and £250, patios often start around £90, and London sits at the upper end. Beyond the number, there are clear signs of a fair quote: fixed in advance, clear about what’s included, and from a company that’s insured and uses the right equipment.

Frequently asked questions
Most UK driveways cost about £2 to £5 per square metre, or £150 to £250 for a standard 40 to 50 square metre driveway. Patios are typically £5 to £9 per square metre, and decking £8 to £14. Heavily soiled areas and extras like oil removal can push the price up. These figures are averages from MyJobQuote and MyBuilder, checked in September 2026.
A small driveway under 30 square metres is around £100. A medium one of 30 to 50 square metres is typically £150 to £250, and a large one of 50 to 70 square metres is £250 to £400. Heavy moss, weeds or oil stains can add £50 to £200. Prices come from MyBuilder, checked in September 2026.
Patio cleaning is typically £5 to £9 per square metre, or roughly £90 to £250 for a patio up to 30 square metres. Natural stone needs more care than concrete flags, which can affect the time and price. A treatment afterwards to slow regrowth is sometimes an optional extra, so check whether it’s included.

Jobs vary, and so does what’s included. Differences in area, surface type, condition, equipment and location all change the price. A very low quote often means something is being skipped, such as the right equipment, oil treatment or insurance.
The hire fee looks cheaper, but it doesn’t include your time, the cleaning products or the risk of getting it wrong. Consumer machines often lack a surface cleaner attachment, which leads to stripes and blasted joints. Mistakes on block paving or natural stone can cost more to fix than a professional clean.
A fair price should cover the right equipment for your surface, pressure set to suit the material, and a clean of the full area. It should also include before and after photos and confirmed public liability insurance. Oil stain treatment and joint re sanding are sometimes quoted separately, so ask.
Yes. Block paving takes longer because of the joints, and natural stone needs lower pressure and more care. Concrete and tarmac are usually quicker to clean. The surface decides the technique, and the technique affects the time.
Often, yes, because oil needs a degreaser applied before the wash. It takes extra time and product. Always ask whether oil treatment is included in the quote, and be realistic about old or deep stains, which may not shift completely.
It can be a red flag. If a quote is well below the ranges above for your size of area, ask what’s missing. Very low prices often mean the wrong equipment, no insurance, or a rushed job with no photos. Compare what’s included, not just the number at the bottom.
MyJobQuote estimates 3 to 6 hours for a patio up to 30 square metres and 2 to 6 hours for a driveway up to 60 square metres. Larger areas can take most of a day. Block paving with heavy moss in the joints takes longer. We give a realistic time estimate when we quote.
