Overview

How it works
Step 1
Tarmac, block paving, resin-bound or imprinted concrete, and roughly how many square metres — that sets both the pressure setting and the price.
Step 2
Cleaning, any re-sanding or resealing and the tip fee for spent sand are shown as separate lines rather than folded into one number.
Step 3
A biocide is applied to joints and shaded corners before washing, because pressure alone leaves roots behind that regrow within weeks.
Step 4
Hot water for tarmac and concrete; a stepped-down pressure and softer head for block paving, resin-bound and imprinted surfaces.
Step 5
Kiln-dried sand is brushed and vibrated into block paving joints once dry; sealant is reapplied on resin-bound and imprinted concrete driveways that include it.
Why choose us
Wastewater containing detergent or biocide is contained and directed away from surface water drains during the clean, in line with water company trade effluent guidance, rather than allowed to run off into the road gutter.
One technician and a van-mounted hot-water pressure washer for most driveways; two on larger block-paving jobs where re-sanding is included, since brushing sand in is a second task run alongside the wash. Long driveways and gated entrances; roads are wide and easy for a Luton.
Same-week across every borough, with the pressure and nozzle setting confirmed from your photos before the technician is booked so it isn't decided on arrival. Northwood (Metropolitan) is the nearest station, so a HA6 visit rarely needs a whole morning set aside.
We expect cavity brickwork outside — and timber stud partitions inside, the pattern behind 7,999 households inside the HA6 neighbourhood in HA6, 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, as the Northwood stock goes, where 60% owner-occupation means the same home is booked again rather than a new tenant each year.
Fixed prices
| Job | From | Typical time | What sets the price |
|---|---|---|---|
| Tarmac or plain concrete driveway, up to 20m² | £120 | 1–1.5 hrs | A flat, sealed surface with no joints to protect, so it's the fastest and lowest-risk driveway to hot-water wash at full pressure. |
| Block paving clean only, per m² | £4.50 | By area | Block paving has hundreds of joints per square metre; the pressure is kept low enough not to blow the jointing sand out before we've had the chance to resand it. |
| Block paving clean and re-sand with kiln-dried sand, per m² | £7.50 | By area | Kiln-dried sand has to be brushed in and vibrated down into every joint once the paving is fully dry, which is what actually stops the blocks rocking loose over winter. |
| Resin-bound driveway clean, per m² | £5.50 | By area | Resin-bound surfaces are cleaned at a lower pressure with a soft rotary head, because a standard turbo nozzle can strip aggregate out of the resin binder. |
| Pattern-imprinted concrete clean and reseal, per m² | £6.50 | By area | Imprinted concrete needs its sealant reapplied after cleaning or the colour fades and the surface starts absorbing oil and tyre marks again within a season. |
| Oil stain or moss treatment, per stain or per m² | £15 / £3 | Added to visit | Oil needs a degreaser dwell time before the hot-water wash; moss and algae need a biocide treatment first so it doesn't just regrow from the roots left in the joints. |

Scope
Hello Services provides excellent jet washing service that completely transformed my driveway , highly recommended at this price .
Sardar gave me a great spring clean and the patio clean with professional chemicals. It was fast and reliable service. Will definitely do it again!
Sardar jet washed my front and back patios. He did a great job, was on time, and communicated well. He checked that I was happy with the work and was very neat and tidy while working and afterwards.

Working in Northwood
7,999 households sit inside the HA6 neighbourhood covering Northwood. The build is period conversion, the tenure profile owner-occupier-led, and 38% of those homes are flats.
The owner-occupier-led mix here (60% owned, 25% privately rented) means a HA6 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Expect cavity brickwork outside — and timber stud partitions inside, the pattern behind 7,999 households inside the HA6 neighbourhood behind the plaster in HA6. That is why fixings are picked in the room rather than off a van shelf, and why a four-hole bracket with two screws in a stud and two in fresh air, as the Northwood stock goes, where 60% 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.
Affluent Metroland suburb of large houses, private schools and golf courses. That character decides the practical detail of driveway cleaning here far more than the borough boundary does. Northwood 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: long driveways and gated entrances; roads are wide and easy for a Luton. Northwood (Metropolitan) is the nearest station, and one technician and a van-mounted hot-water pressure washer for most driveways; two on larger block-paving jobs where re-sanding is included, since brushing sand in is a second task run alongside the wash.

Tarmac or plain concrete driveway, up to 20m² starts at £120 in Northwood — and Northwood Golf Club a few streets away, with this being London Borough of Harrow territory, and every job is quoted as a fixed written price before a fitter is booked. Surface type first, then area. Block paving and resin-bound surfaces cost more per square metre than plain concrete because the lower pressure needed takes longer to cover the same area in this 38% flats neighbourhood — and 38% of homes here being flats, with Harrow parking rules in play, and re-sanding or resealing is a second pass, not an add-on to the wash.
Yes — IKEA, Argos, Wayfair, Made and independent brands are all built to the manufacturer's instructions on HA6 jobs, with a median age of 40 in this neighbourhood. We are independent of every retailer; the names simply describe what we assemble in Northwood most weeks on this side of Harrow, with this being London Borough of Harrow territory.
5–2 hours. Sliding-door and corner wardrobes take two to four times as long because the tracks have to be dead level in Northwood, with Harrow parking rules in play.
That is exactly why we build in the room it will live in in this 38% flats neighbourhood. With 38% of Northwood homes being flats, narrow hallways and tight turns are the norm on this side of Harrow, with 7,999 households on this patch — and 38% of homes here being flats, so anything that will not pass a doorway once assembled is built where it stands.
