In Hanwell (W7) the split is 45% flats to 55% houses over 3,219 households, and the stock is mainly Victorian.
Because 31% of Hanwell is privately rented and 14% socially rented, a lot of W7 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are some of it dry-lined during a later refurbishment, over solid London stock brick, which is why London Borough of Ealing kerb rules get settled before the van is loaded, so the fixing that matters in Hanwell is chosen on site — the usual failure here is fixings landing in soft lime mortar joints instead of the brick body, as the Hanwell stock goes, the reality on the streets around The Wharncliffe Viaduct.
Hanwell 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 — the Wharncliffe Viaduct, the Brent valley and a village-like clock tower centre — which is why a W7 quote is not a Ealing average.
Getting to the door matters as much as the job: narrow bridges over the Brent, permit bays near the station and driveways elsewhere. Hanwell (Elizabeth line) is the nearest station, and one cleaner for a flat; two for a house, so the property is finished in one visit rather than split across a day.
