Merton · SW20 · Patio and decking cleaning
Same-week slots · Fully insured · Local Raynes Park fitters · Fixed written pricesBooking patio and decking cleaning near Cottenham Park? Driveways on most roads; the level crossing and station parade congest at peak, and that is planned into the slot rather than discovered on the day. Prices start at £4.50 and are fixed before we travel. Units are built in the room they live in, then wall-anchored where they need it.
Overview
This page prices patio and decking cleaning for Raynes Park SW20 specifically: mainly Edwardian stock, 35% privately rented and 3,570 households in total. Work starts at £4.50, fixed in writing, with parking and London Borough of Merton permit rules costed before an insured fitter travels.
How it works
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.
Why choose us
Same-week across every borough, with weekend slots common through spring and early summer when garden and roof-terrace use picks up. Raynes Park (South Western) is the nearest station, so a SW20 visit rarely needs a whole morning set aside.
We expect lath and plaster over timber studs; locally that also means with solid brick on the party and external walls, where 51% owner-occupation means the same home is booked again rather than a new tenant each year in SW20, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is which crumbles the key and drops the panel — and a plasterboard plug spun into lime plaster, which is what a 51% flat share across the ONS neighbourhood covering Raynes Park actually produces.
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.
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. Driveways on most roads; the level crossing and station parade congest at peak.
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. |

Scope
I asked Hello Services for a deep clean of the carpets of a house in London we were moving into. Loqman and his colleague arrived on time and were incredibly fast in firstly hoovering all to be worked on and then deep cleaning a total of seven sets of carpets across our first and second… Read in full →
Thankyou to Nicole and Marius and colleagues for a superb clean of our family home. It was done under difficult circumstances with removal people still emptying the property of furniture and boxes around them as we were moving out after nearly 40 years. We were extremely happy with the end result and am sure that… Read in full →

Working in Raynes Park
3,570 households sit inside the SW20 neighbourhood covering Raynes Park. The build is mainly Edwardian, the tenure profile renter-heavy, and 51% of those homes are flats.
With 35% private renting against 51% owner-occupied, most SW20 bookings land on a move-in day rather than a weekend.
Walls are lath and plaster over timber studs; locally that also means with solid brick on the party and external walls, where 51% owner-occupation means the same home is booked again rather than a new tenant each year, so the fixing that matters in Raynes Park is chosen on site — the usual failure here is which crumbles the key and drops the panel — and a plasterboard plug spun into lime plaster, which is what a 51% flat share across the ONS neighbourhood covering Raynes Park actually produces.
Raynes Park is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it. What shapes the job more is the neighbourhood itself — a quiet family suburb of interwar semis with Cottenham Park nearby — which is why a SW20 quote is not a Merton average.
Getting to the door matters as much as the job: driveways on most roads; the level crossing and station parade congest at peak. Raynes Park (South Western) is the nearest station, and 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.

50 in Raynes Park, and every job is quoted as a fixed written price before a fitter is booked for Raynes Park (SW20) addresses, with 3,570 households on this patch. 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 on the streets near Cottenham Park — and 51% of homes here being flats, with 30% one-person households here.
Yes — IKEA, Argos, Wayfair, Made and independent brands are all built to the manufacturer's instructions for Raynes Park (SW20) addresses, with 35% of SW20 homes being privately rented. We are independent of every retailer; the names simply describe what we assemble in Raynes Park most weeks, with Cottenham Park a few streets away.
5–2 hours. Sliding-door and corner wardrobes take two to four times as long because the tracks have to be dead level on Merton bookings, with this being London Borough of Merton territory.
That is exactly why we build in the room it will live in across SW20. With 51% of Raynes Park homes being flats, narrow hallways and tight turns are the norm around Raynes Park (South Western) — and 14% social-rented stock nearby, with 35% of SW20 homes being privately rented, so anything that will not pass a doorway once assembled is built where it stands.
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; Deep oil or paint staining that has soaked into porous stone and may need professional poulticing rather than a surface wash; Structural work on raised decking or a roof terrace balustrade on the streets near Cottenham Park — and 14% social-rented stock nearby, with 35% of SW20 homes being privately rented, which needs a qualified joiner or builder. Anything outside that scope is quoted separately so the Raynes Park SW20 price you agree is the price you pay across SW20, with this being a short walk from Raynes Park (South Western).
All three. With 35% of Raynes Park privately rented and 51% owner-occupied, roughly half the SW20 diary is agent- or landlord-instructed and invoiced separately from the person at the door on this side of Merton — and 3,570 households on this patch, with 51% of homes here being flats.
Cottenham Park is the marker we route to on the Raynes Park rounds, with Merton parking rules in play, and driveways on most roads; the level crossing and station parade congest at peak. A SW20 slot added to an existing Merton round usually lands the same week rather than the next for Raynes Park (SW20) addresses, with 51% of homes here being flats.
