Barnet · EN4 · Patio and decking cleaning
Same-week slots · Fully insured · Local New Barnet and Cockfosters fitters · Fixed written pricesNew Barnet and Cockfosters EN4 is a regular stop on our Barnet round. Station suburbs on the Hertfordshire edge, with Trent Park on the doorstep, so patio and decking cleaning here is quoted on the street the job is on — from £4.50, in writing, with insured fitters, every fixing torqued, and the flat-pack packaging taken away.
Overview
Patio and decking cleaning in New Barnet and Cockfosters EN4 is a fixed-price visit for owner-occupier-led homes in Barnet, most of them inter-war. 6,400 households sit inside this EN4 patch, 46% of them flats, so we quote on access near Trent Park 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
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 almost everywhere; Cockfosters Road is fast and hard to stop on.
Same-week across every borough, with weekend slots common through spring and early summer when garden and roof-terrace use picks up. Cockfosters (Piccadilly) is the nearest station, so a EN4 visit rarely needs a whole morning set aside.
We expect cavity brickwork outside, over timber stud partitions inside — a median age of 38 in this neighbourhood shapes what gets ordered here in EN4, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is a four-hole bracket with two screws in a stud and two in fresh air on these streets — measured on the walk in from Cockfosters (Piccadilly) rather than assumed from a map.
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.
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.

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.
