Harrow · HA6 · Patio and decking cleaning
Same-week slots · Fully insured · Local Northwood fitters · Fixed written pricesBooking patio and decking cleaning near Northwood Golf Club? Long driveways and gated entrances; roads are wide and easy for a Luton, 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
Patio and decking cleaning in Northwood HA6 is a fixed-price visit for owner-occupier-led homes in Harrow, most of them period conversion. 7,999 households sit inside this HA6 patch, 38% of them flats, so we quote on access near Northwood Golf Club rather than a London average.
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. Northwood (Metropolitan) is the nearest station, so a HA6 visit rarely needs a whole morning set aside.
We expect cavity brickwork outside, over timber stud partitions inside, which is why London Borough of Harrow kerb rules get settled before the van is loaded in HA6, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is Northwood gives us a four-hole bracket with two screws in a stud and two in fresh air, and with 25% of homes here privately rented, it sets the booking date as often as the job does.
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. Long driveways and gated entrances; roads are wide and easy for a Luton.
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 Northwood
Northwood HA6 is period conversion and owner-occupier-led: 38% of homes here are flats and 62% are houses, across 7,999 households (ONS Census 2021).
Because 25% of Northwood is privately rented and 16% socially rented, a lot of HA6 work is agreed with a landlord or managing agent rather than the person opening the door.
Northwood substrates run to cavity brickwork outside, over timber stud partitions inside, which is why London Borough of Harrow kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because Northwood gives us a four-hole bracket with two screws in a stud and two in fresh air, and with 25% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a HA6 customer twice.
Northwood 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 — affluent Metroland suburb of large houses, private schools and golf courses — which is why a HA6 quote is not a Harrow average.
On access, long driveways and gated entrances; roads are wide and easy for a Luton — one reason 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. Fitters travelling in use Northwood (Metropolitan).

50 in Northwood, and every job is quoted as a fixed written price before a fitter is booked around Northwood (Metropolitan), with Northwood Golf Club a few streets away. 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 in Northwood — and 29% one-person households here, with 25% of HA6 homes being privately rented.
Yes — IKEA, Argos, Wayfair, Made and independent brands are all built to the manufacturer's instructions on HA6 jobs, with Harrow parking rules in play. We are independent of every retailer; the names simply describe what we assemble in Northwood most weeks on this side of Harrow, with 29% one-person households here.
5–2 hours. Sliding-door and corner wardrobes take two to four times as long because the tracks have to be dead level on this side of Harrow, with 16% social-rented stock nearby. With 38% of homes in Northwood being flats, we plan the route up front.
That is exactly why we build in the room it will live in on HA6 jobs. With 38% of Northwood homes being flats, narrow hallways and tight turns are the norm on the Northwood rounds — and 16% social-rented stock nearby, with 60% owner-occupation locally, 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 around Northwood (Metropolitan) — and 60% owner-occupation locally, with Harrow parking rules in play, which needs a qualified joiner or builder. Anything outside that scope is quoted separately so the Northwood HA6 price you agree is the price you pay across HA6, with 38% of homes here being flats.
All three. With 25% of Northwood privately rented and 60% owner-occupied, roughly half the HA6 diary is agent- or landlord-instructed and invoiced separately from the person at the door around Northwood (Metropolitan) — and Northwood Golf Club a few streets away, with 29% one-person households here.
Northwood Golf Club is the marker we route to on the streets near Northwood Golf Club, with 7,999 households on this patch, and long driveways and gated entrances; roads are wide and easy for a Luton. A HA6 slot added to an existing Harrow round usually lands the same week rather than the next across HA6, with 29% one-person households here.
