Patio and decking cleaning London

Patio and decking cleaning in London the right pressure for stone, timber or composite.

Concrete flag patios, York stone and sandstone terraces, and softwood or composite decking cleaned across all 33 London gardens, balconies and roof terraces, with the pressure set for what's underfoot rather than one setting for everything. Deck board gaps are cleared so water drains through instead of pooling on the joists, and roof terraces with no outside tap are supplied by bowser rather than skipped or charged a mystery surcharge.

London pricing

London patio and decking cleaning prices.

Concrete is the baseline rate because it takes full pressure with no risk to the finish. Natural stone and composite decking both cost more per square metre — not because they're harder to clean, but because the lower pressure each needs takes longer to cover the same area.
London patio and decking cleaning prices by surface
JobLondon fromTypical timeWhy the London price differs
Concrete flag patio, per m²£4.50By areaManufactured flags take a standard rotary surface cleaner at full pressure without risk to the finish.
York stone or sandstone patio, per m²£6.50By areaNatural stone is more porous and softer than concrete, so it's cleaned at lower pressure with a specialist stone-safe cleaner.
Softwood decking clean, per m²£5By areaThe pressure is kept low and the nozzle kept moving, since a static jet will fur the grain and shorten the board's life.
Composite decking clean, per m²£5.50By areaA wide fan nozzle and lower bar pressure are used, since a narrow jet can strip the capping layer that gives composite its colour and grip.
Decking oiling or re-staining after cleaning, per m²£4Added to visitSoftwood decking needs re-oiling once fully dry; this is a separate pass because it can only start after the boards have dried out.
Roof terrace or balcony deck, per m²£7By areaNo mains tap on most roof terraces means water is carried up by bowser, and drainage outlets have to be checked and cleared as part of the visit.

Domestic prices are the total you pay. Commercial and landlord invoices are quoted plus VAT at 20%. ULEZ, the Congestion Charge where it applies, permits and bay suspensions are itemised in the written quote, never added afterwards.

Working in London

Why London patios and decks aren't a one-setting job.

Two gardens next door to each other can need completely different pressure, chemical and drying approaches once the surface material changes.

York stone needs a stone-safe cleaner, not just lower pressure

York stone and sandstone patios on London's Victorian and Edwardian properties are laid natural, porous stone rather than manufactured concrete, and standard driveway-strength detergent and pressure can etch or pit the surface over repeated cleans. Conservation area guidance in several boroughs treats original stone terracing on listed buildings as part of the protected fabric, not just a garden surface.

We use a lower pressure and a specialist stone-safe cleaning product on natural stone patios rather than the setting used on concrete flags, protecting both the surface finish and, where relevant, the property's conservation status.

Composite decking is cleaned differently to timber, not the same way

Composite decking, increasingly common on London roof terraces and small rear gardens for its low maintenance, has a capping layer that gives it colour and slip resistance — and a narrow, high-pressure jet can strip that capping away, leaving faded, rougher patches that never fully blend back in.

We use a wide fan nozzle and a lower bar pressure on composite boards specifically, which is different from the setting we use on softwood decking even though both look similar from a distance.

Deck board gaps are where the real damage happens

Leaves, moss and grit trapped in the gaps between deck boards stop rainwater draining through to the joists below, and that trapped moisture is what actually rots softwood decking and corrodes the fixings — not the surface algae that's visible from above.

Clearing deck board gaps is part of every deck clean we do, not an optional extra, because a clean-looking surface over blocked drainage gaps is a problem building underneath it.

Roof terraces need water carried up and drainage checked down

Roof terraces and raised decking added to London flats, common across Nine Elms, Stratford and Canary Wharf conversions, usually have no outside tap, so cleaning water has to be carried up by bowser rather than run from a hose. Several of these terraces also needed planning permission or a lease variation when built, and their drainage outlets are exactly what can fail quietly if leaves and debris build up around them.

We check and clear drainage outlets as part of every roof terrace clean, since a blocked gulley on a terrace is what turns into a leak into the flat below, not just a cosmetic issue.

London questions

London patio and decking cleaning questions.

Common questions

Frequently asked questions.

  • How much does it cost to clean a patio or deck in London?

    Concrete flag patios start at £4.50 per m², York stone and sandstone at £6.50 per m² for the lower pressure they need. Softwood decking is £5 per m² and composite decking £5.50 per m². Roof terraces and balconies are £7 per m² to cover bowser water and a drainage check.

  • Will jet washing damage my York stone patio?

    Not with the method we use — lower pressure and a specialist stone-safe cleaner rather than standard driveway detergent. Full pressure on porous natural stone can etch or pit the surface over repeated cleans, so we always step it down on York stone and sandstone.

  • Is composite decking cleaned the same way as timber decking?

    No. Composite decking is cleaned with a wide fan nozzle and lower bar pressure, since a narrow high-pressure jet can strip the capping layer that gives composite boards their colour and grip. Softwood decking uses a different, moving-nozzle technique to avoid furring the grain.

  • Do you clear the gaps between deck boards?

    Yes, on every deck clean. Trapped leaves and grit in the gaps stop water draining through to the joists, and that trapped moisture — not surface algae — is usually what actually rots decking over time.

  • Can you clean a roof terrace with no outside tap?

    Yes. Water is carried up by bowser where there's no mains supply, and we check drainage outlets are clear once the clean is finished, since a blocked gulley on a terrace can lead to a leak into the flat below.

  • Do you oil or re-stain decking after cleaning?

    Yes, as an optional add-on at £4 per m², done once the boards have fully dried out. It's the step that keeps softwood decking weatherproof after a clean strips the old, worn finish off.

  • Is my natural stone patio protected if the property is listed?

    We use a lower pressure and stone-safe cleaner on all natural stone patios regardless, which is the approach that also respects conservation area guidance treating original stone terracing as part of a listed building's protected fabric.
