Driveway pressure washing cost varies more by surface type than most people expect, since block paving, tarmac and concrete all behave differently under a jet wash and take different amounts of time to do properly. Size is the other big factor.
This guide breaks the price down by surface and size, and explains the difference between a straightforward clean and a clean-and-seal package, which costs more but lasts considerably longer.
Driveway pressure washing prices by surface and size
As a rough guide, expect £3-£6 per m² for a straightforward pressure wash clean, so a small driveway around 20-30m² might cost £80-£150, a medium driveway 30-50m² around £150-£250, and a large or double driveway over 50m² £250-£400+. Block paving generally sits toward the higher end because of the extra time needed to clean between blocks and in the joints.
Tarmac and plain concrete are quicker to clean since there are no joints to work into, so they often price toward the lower end of the range for a given size. Resin-bound or resin-bonded driveways need gentler pressure and specific technique, which can push the price up slightly.
Clean-only versus clean and seal packages
A clean-only service removes moss, algae, oil staining and general grime, leaving the driveway looking dramatically better, but with nothing to slow down how quickly dirt and growth return. Prices for clean-only sit in the ranges above.
A clean and seal package adds a protective sealant after cleaning, which locks in jointing sand on block paving, gives a richer colour, and significantly slows moss and weed regrowth. This typically adds £4-£10 per m² on top of the clean price, so a medium driveway package might run £350-£600 all in. It costs more upfront but usually means the driveway needs cleaning far less often afterward, which is worth factoring into the comparison.
What affects the final price
Beyond surface and size, oil stains, tyre marks and rust from garden furniture or bins need extra treatment time and sometimes a specific degreasing product, which can add a modest surcharge. Heavy moss growth in block paving joints, particularly on older or unsealed driveways, also adds time, since it has to be worked out of every joint rather than just rinsed off a flat surface.
Access matters too: a driveway that's easy to reach with equipment from the road prices more favourably than one needing hoses run a long distance, or a driveway shared with a neighbour requiring careful boundary work and a bit more care around where debris and wastewater end up.
Getting the most accurate quote
The best quotes come from either a site visit or clear photos showing the driveway's condition, size and surface type, since a phone estimate for a heavily stained or moss-covered driveway can be wildly different from the eventual price once the true condition is seen. It's reasonable to ask for a firm price rather than a vague estimate wherever the driveway is straightforward to assess.
If you're planning to sell your home or have visitors for a specific event, book with a bit of lead time, since driveway cleaning (particularly with sealing) needs dry weather to finish and cure properly, and popular dates can book up quickly in drier spells.
