The W7 stock around The Wharncliffe Viaduct is mainly Victorian. ONS records 45% flats, 55% houses and 3,219 households in Hanwell.
Private renting sits at 31% and owner-occupation at 55%; the first group books clearance services at short notice, the second plans it.
Hanwell substrates run to solid London stock brick; locally that also means some of it dry-lined during a later refurbishment — the reality on the streets around The Wharncliffe Viaduct. Nothing is drilled until the wall has been sounded, because in W7, fixings landing in soft lime mortar joints instead of the brick body — the pattern behind 3,219 households inside the W7 neighbourhood is the mistake that costs a W7 customer twice.
Two streets can behave very differently in Hanwell: the Wharncliffe Viaduct, the Brent valley and a village-like clock tower centre. The quote reflects the street the job is actually on. Hanwell is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Narrow bridges over the Brent, permit bays near the station and driveways elsewhere. Nearest station is Hanwell (Elizabeth line), and standard crews are two people with a 3.5-tonne Luton; bigger clears run two vans or return the same day rather than overfilling.
