Overview
Patio and decking cleaning in Harrow HA1, explained
This page prices patio and decking cleaning for Harrow HA1 specifically: mainly Victorian stock, 31% privately rented and 14,108 households in total. Work starts at £4.50, fixed in writing, with parking and London Borough of Harrow permit rules costed before an insured fitter travels.
How it works
How patio and decking cleaning works in Harrow
Five steps, the same on every HA1 job, so you know what happens before you commit. Terraced houses with solid London stock brick and later plasterboard linings on these streets — and one-way town centre with timed loading; the hill lanes are narrow and steep is what we plan for here.
Step 1
Tell us the surface and access
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
Fixed written quote
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
Clear and pre-treat
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
Wash at the right pressure
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
Dry, treat and hand back
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
Why Harrow customers book us
Four things decide whether a HA1 job goes well, and none of them are visible from a price list.
Crew sized to the job
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. One-way town centre with timed loading; the hill lanes are narrow and steep.
Booked around your day
Same-week across every borough, with weekend slots common through spring and early summer when garden and roof-terrace use picks up. Harrow-on-the-Hill (Metropolitan, Chiltern) is the nearest station, so a HA1 visit rarely needs a whole morning set aside.
Harrow walls, not generic walls
We expect solid London stock brick in HA1, some of it dry-lined during a later refurbishment, the pattern behind 14,108 households inside the HA1 neighbourhood in HA1, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is Harrow gives us fixings landing in soft lime mortar joints instead of the brick body, where 59% owner-occupation means the same home is booked again rather than a new tenant each year.
Fixed prices
Patio and decking cleaning prices in Harrow
Fixed prices for HA1 and the rest of Harrow. 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.
| 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. |

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.
Scope
What's included in Harrow
The same scope across HA1, whether the job is a single item or a full room.
Included in the price
- Standard on Harrow bookings: surface identified before we start — concrete, natural stone, softwood or composite — and the pressure and nozzle set for it, allowing for the 31% of HA1 homes that are privately rented and need the landlord's sign-off
- Algae, moss and lichen in shaded, north-facing corners treated with a biocide first rather than pressure-blasted alone, noted on the Harrow job sheet so the next visit starts from it
- In Harrow: deck board gaps cleared of trapped leaves and debris so water drains through rather than pooling and rotting the joists, timed against the walk in from Harrow-on-the-Hill (Metropolitan, Chiltern)
- On HA1 jobs: furniture and planters moved before cleaning and repositioned afterwards, agreed on the doorstep in Harrow before anything is unpacked
- Standard on Harrow bookings: wastewater and any cleaning product run-off directed away from surface water drains during the wash, with 14,108 households in this neighbourhood, it is the question we are asked most
- A drainage check on roof terraces and balconies to confirm outlets are clear once the clean is finished, checked on every HA1 visit
Not included
- Replacing rotten, cracked or delaminating deck boards — that's a repair job, quoted separately by our decking team, and we will say so before the HA1 visit rather than on the day
- Repointing or re-bedding natural stone patio slabs that have come loose or sunk, handled by London Borough of Harrow or a specialist contractor instead
- Deep oil or paint staining that has soaked into porous stone and may need professional poulticing rather than a surface wash, quoted separately if you need it arranged in HA1
- Structural work on raised decking or a roof terrace balustrade, which needs a qualified joiner or builder, outside the fixed price on Harrow bookings

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.

Harrow HA1 at a glance
Published figures for the neighbourhood that covers Harrow — the numbers that actually change a patio and decking cleaning quote.
In Harrow (HA1) the split is 38% flats to 62% houses over 14,108 households, and the stock is mainly Victorian.
Because 31% of Harrow is privately rented and 10% socially rented, a lot of HA1 work is agreed with a landlord or managing agent rather than the person opening the door.
Expect solid London stock brick in HA1, some of it dry-lined during a later refurbishment, the pattern behind 14,108 households inside the HA1 neighbourhood behind the plaster in HA1. That is why fixings are picked in the room rather than off a van shelf, and why Harrow gives us fixings landing in soft lime mortar joints instead of the brick body, where 59% owner-occupation means the same home is booked again rather than a new tenant each year is the fault we are called back to undo.
Town centre shopping, St Ann's mall and the school on the hill above. That character decides the practical detail of patio and decking cleaning here far more than the borough boundary does. Harrow is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: one-way town centre with timed loading; the hill lanes are narrow and steep. Harrow-on-the-Hill (Metropolitan, Chiltern) 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.

Common questions
Patio and decking cleaning in Harrow HA1 — your questions.
How much does patio and decking cleaning cost in Harrow HA1?
50 in Harrow, and every job is quoted as a fixed written price before a fitter is booked on this side of Harrow, with Harrow School and St Mary's Church 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 this 38% flats neighbourhood — and 25% one-person households here, with 31% of HA1 homes being privately rented.
Do you assemble IKEA and other flat-pack furniture in Harrow HA1?
Yes — IKEA, Argos, Wayfair, Made and independent brands are all built to the manufacturer's instructions on this side of Harrow, with a median age of 38 in this neighbourhood. We are independent of every retailer; the names simply describe what we assemble in Harrow most weeks across HA1, with this being a short walk from Harrow-on-the-Hill (Metropolitan, Chiltern).
How long does flat-pack assembly take in Harrow?
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 38% of homes here being flats.
Will a built wardrobe fit through a Harrow doorway?
That is exactly why we build in the room it will live in on this side of Harrow. With 38% of Harrow homes being flats, narrow hallways and tight turns are the norm in Harrow — and this being London Borough of Harrow territory, with this being a short walk from Harrow-on-the-Hill (Metropolitan, Chiltern), so anything that will not pass a doorway once assembled is built where it stands.
Do you handle difficult access in Harrow?
One-way town centre with timed loading; the hill lanes are narrow and steep around Harrow-on-the-Hill (Metropolitan, Chiltern). Where a permit or a suspended bay is needed in London Borough of Harrow it is itemised on the quote before the visit, never added afterwards in Harrow, with Harrow parking rules in play.
Are your fitters insured for work in HA1?
Wastewater containing detergent or biocide is contained and directed away from surface water drains during the clean on this side of Harrow — and 62% of Harrow homes being houses, with this being a short walk from Harrow-on-the-Hill (Metropolitan, Chiltern), and drainage outlets on roof terraces and balconies are checked and cleared as part of the visit. That paperwork is what most Harrow letting agents and managing agents ask for before work starts in a leasehold flat across HA1, with 31% of HA1 homes being privately rented.
What is not included in patio and decking cleaning in Harrow?
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 this side of Harrow, with 14,108 households on this patch — and 59% owner-occupation locally, which needs a qualified joiner or builder. Anything outside that scope is quoted separately so the Harrow HA1 price you agree is the price you pay on HA1 jobs, with 25% one-person households here.
