The W7 stock around The Wharncliffe Viaduct is mainly Victorian. ONS records 45% flats, 55% houses and 3,219 households in Hanwell.
31% of households rent privately and 55% own, which is why shed clearance and removal demand here peaks around tenancy changeovers and completion dates.
Walls are some of it dry-lined during a later refurbishment, over solid London stock brick — the reality on the streets around The Wharncliffe Viaduct, so the fixing that matters in Hanwell is chosen on site — the usual failure here is in W7, fixings landing in soft lime mortar joints instead of the brick body — measured on the walk in from Hanwell (Elizabeth line) rather than assumed from a map.
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.
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 two crew and a Luton on a standard timber shed; three crew where the shed is a workshop size, the base is concrete or the only route out is through the house.
