Walk Purley from Purley Rotary Field outwards and the inter-war pattern is obvious: 44% of the 7,502 households in CR8 live in flats, 56% in houses.
26% of households rent privately and 64% own, which is why driveway cleaning demand here peaks around tenancy changeovers and completion dates.
Purley substrates run to some of it dry-lined during a later refurbishment, over solid London stock brick — the pattern behind 7,502 households inside the CR8 neighbourhood. Nothing is drilled until the wall has been sounded, because fixings landing in soft lime mortar joints instead of the brick body on these streets — and with 29% one-person households in Purley, one adult is usually the only pair of hands on site is the mistake that costs a CR8 customer twice.
Two streets can behave very differently in Purley: a downland town at the foot of the Brighton Road hills, with big detached houses above. The quote reflects the street the job is actually on. Purley 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: steep hill roads with sharp turns; driveways on most residential streets. Purley (Southern) 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.
