London patio and decking cleaning · South London
Local patio and decking cleaning for Greenwich and its 10 covered areas. Maritime Greenwich and the Peninsula's towers, then Woolwich, Eltham and the suburbs behind Shooters Hill.
Fixed prices
| Job | From | Typical time | What sets the price |
|---|---|---|---|
| Concrete flag patio, per m² | £4.50 | By area | Manufactured concrete flags take a standard rotary surface cleaner at full pressure without any risk to the finish. |
| York stone or sandstone patio, per m² | £6.50 | By area | Natural stone is more porous and softer than concrete, so it's cleaned at a lower pressure with a specialist stone-safe cleaner rather than the standard detergent. |
| Softwood decking clean, per m² | £5 | By area | Softwood boards need the pressure 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 | £5.50 | By area | Composite boards need a wide fan nozzle and a lower bar pressure than timber, 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 | £4 | Added to visit | Softwood decking needs re-oiling once dry to stay weatherproof; this is priced as a separate pass because it can only start once the boards have fully dried out. |
| Roof terrace or balcony deck, per m² | £7 | By area | No 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, not just the deck surface. |

Roof terrace or balcony deck, per m²
£7 · By area
No 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, not just the deck surface.
Domestic prices are the total you pay; managing agents and landlords are invoiced plus VAT at 20%. Furniture moved off the patio or deck before cleaning and put back after, and clearing debris from drainage gaps between deck boards, are included. Where a bowser or extended hose run is needed for a flat with no outside tap, that's shown as its own line.
Working in Greenwich
The stock in Greenwich is georgian terraces in west greenwich, 1930s eltham semis, woolwich estates and peninsula high-rise, and the mix changes street by street — Abbey Wood (SE2), Blackheath (SE3) and Charlton (SE7) each behave differently on the day.
On the ground, cobbled and one-way streets in the world heritage core, blackwall tunnel approach red routes, and tower-block lift booking on the peninsula. Locally that means steep streets towards the abbey, wide estate roads and new blocks with booked lifts and conservation-area restrictions, narrow village streets and listed staircases. Greenwich sits outside the Congestion Charge zone, so only ULEZ applies to the van and the quote is that much simpler.
York stone and sandstone patios on older Greenwich properties are softer and more porous than concrete flags, and Royal Borough of Greenwich conservation area guidance for the borough's protected streets treats natural stone terracing as original fabric on listed buildings. We use a lower pressure and a specialist stone cleaner rather than the setting used on standard concrete.
Why it looks like this: royal palace and naval hospital on the river, arsenal at woolwich; the peninsula's gasworks became the o2 and new districts.
Scope
Method
Step 1
Concrete, natural stone, softwood or composite, roughly the area, and whether there's an outside tap or the flat needs water carried up by bowser.
Step 2
Priced per square metre for the surface you have, with oiling, re-staining or a bowser water supply shown as separate lines rather than bundled in.
Step 3
Furniture and planters moved, deck board gaps cleared of leaf litter, and algae or lichen in shaded corners given a biocide soak before washing.
Step 4
Concrete at full strength; natural stone, softwood and composite all stepped down to protect the surface, using a wide fan nozzle on composite specifically.
Step 5
Softwood decking is left to dry before any oiling; drainage outlets on roof terraces are checked clear; furniture is put back once the surface is dry underfoot.
Coverage
Also in this borough
Block paving, resin-bound and imprinted concrete driveways cleaned, resanded and sealed.
Front paths, side returns and communal walkways cleaned without disturbing loose flags.
The wider outdoor jet washing hub covering every hard surface we clean.
New garden furniture built and levelled on the patio or deck once it's clean.
Two crew and a Luton or tipper; three where everything has to be carried through a hallway.
A full top-to-bottom clean of the property once it has been emptied.
Cuttings, turf and soil taken to a licensed composting site rather than to landfill.
Concrete flag patio, per m² starts at £4.50 in Greenwich, and the ladder runs up to £7 for the largest job on the table above. Surface material first — natural stone and composite decking cost more per square metre than concrete because both need a lower pressure that takes longer to cover the same area — then access, since a roof terrace with no outside tap needs water carried up rather than run from a hose. The borough is outside the Congestion Charge zone, so there is no charge to pass on — only ULEZ, which our vans are compliant with.
We cover the whole borough: SE10, SE18, SE2, SE28, SE3, SE7 and SE9. On the ground that includes Abbey Wood, Blackheath, Charlton, Eltham, Greenwich and Greenwich Peninsula.
Same-week across every borough, with weekend slots common through spring and early summer when garden and roof-terrace use picks up. South London is covered by crews already working in the borough, so travel time is not billed on top.
Cobbled and one-way streets in the World Heritage core, Blackwall Tunnel approach red routes, and tower-block lift booking on the Peninsula. Where a permit or a bay suspension is needed we arrange it with Royal Borough of Greenwich and show the cost in the quote before you agree it. Nothing is added afterwards.
Yes. Georgian terraces in West Greenwich, 1930s Eltham semis, Woolwich estates and Peninsula high-rise is exactly the stock we work in daily. Where there is no lift, the crew size is set by the floor level at quote stage, so a third-floor walk-up is priced as a third-floor walk-up rather than re-quoted on the doorstep.
Wastewater containing detergent or biocide is contained and directed away from surface water drains during the clean, and drainage outlets on roof terraces and balconies are checked and cleared as part of the visit. Certificates go out with the booking confirmation, which is what Royal Borough of Greenwich tenancies and most local managing agents ask for.
One technician for a standard garden patio or deck; two for a roof terrace or balcony where water has to be carried up by bowser and furniture moved through a lift or stairwell. Vehicles are ULEZ-compliant, which matters in every Greenwich postcode, and the crew carries everything needed to complete the job in one visit.
Replacing rotten, cracked or delaminating deck boards — that's a repair job, quoted separately by our decking team, Repointing or re-bedding natural stone patio slabs that have come loose or sunk and Deep oil or paint staining that has soaked into porous stone and may need professional poulticing rather than a surface wash. If something on that list turns up in Greenwich, we tell you at survey and point you at the right trade rather than taking the booking anyway.

Thankyou to Nicole and Marius and colleagues for a superb clean of our family home.
