Fixed written quote from £4.50, insured fitters, every fixing torqued, and the flat-pack packaging taken away.


Overview
This page prices patio and decking cleaning for Colliers Wood SW19 specifically: mainly Victorian stock, 44% privately rented and 4,286 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
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. High Street red route, riverside estate roads and new blocks with booked lifts.
Same-week across every borough, with weekend slots common through spring and early summer when garden and roof-terrace use picks up. Colliers Wood (Northern) is the nearest station, so a SW19 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, which is why London Borough of Merton kerb rules get settled before the van is loaded in SW19, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is a plasterboard plug spun into lime plaster in SW19, which crumbles the key and drops the panel, which is what a 67% flat share across the ONS neighbourhood covering Colliers Wood actually produces.
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 Colliers Wood
In Colliers Wood (SW19) the split is 67% flats to 33% houses over 4,286 households, and the stock is mainly Victorian.
Because 44% of Colliers Wood is privately rented and 9% socially rented, a lot of SW19 work is agreed with a landlord or managing agent rather than the person opening the door.
Colliers Wood substrates run to lath and plaster over timber studs; locally that also means with solid brick on the party and external walls, which is why London Borough of Merton kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in SW19, which crumbles the key and drops the panel, which is what a 67% flat share across the ONS neighbourhood covering Colliers Wood actually produces is the mistake that costs a SW19 customer twice.
The Wandle trail, Merton Abbey Mills and big-box retail on the High Street. That character decides the practical detail of patio and decking cleaning here far more than the borough boundary does. Colliers Wood is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
High Street red route, riverside estate roads and new blocks with booked lifts. Nearest station is Colliers Wood (Northern), 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 Colliers Wood, and every job is quoted as a fixed written price before a fitter is booked on the Colliers Wood rounds, with a median age of 34 in this neighbourhood. 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 for Colliers Wood (SW19) addresses — and 9% social-rented stock nearby, with 4,286 households on this patch.
Yes — IKEA, Argos, Wayfair, Made and independent brands are all built to the manufacturer's instructions on the Colliers Wood rounds, with 9% social-rented stock nearby. We are independent of every retailer; the names simply describe what we assemble in Colliers Wood most weeks on Merton bookings, with 47% owner-occupation locally.
5–2 hours. Sliding-door and corner wardrobes take two to four times as long because the tracks have to be dead level on the streets near Merton Abbey Mills, with 44% of SW19 homes being privately rented.
That is exactly why we build in the room it will live in on Merton bookings. With 67% of Colliers Wood homes being flats, narrow hallways and tight turns are the norm in this 67% flats neighbourhood — and 4,286 households on this patch, with Merton parking rules in play, 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 in Colliers Wood, with this being a short walk from Colliers Wood (Northern) — and a median age of 34 in this neighbourhood, which needs a qualified joiner or builder. Anything outside that scope is quoted separately so the Colliers Wood SW19 price you agree is the price you pay for Colliers Wood (SW19) addresses, with 47% owner-occupation locally.
All three. With 44% of Colliers Wood privately rented and 47% owner-occupied, roughly half the SW19 diary is agent- or landlord-instructed and invoiced separately from the person at the door on Merton bookings — and 67% of homes here being flats, with 29% one-person households here.
Merton Abbey Mills is the marker we route to on the Colliers Wood rounds, with a median age of 34 in this neighbourhood, and high Street red route, riverside estate roads and new blocks with booked lifts. A SW19 slot added to an existing Merton round usually lands the same week rather than the next on SW19 jobs, with 4,286 households on this patch.
