Walk Bromley-by-Bow from Three Mills Island on the River Lea outwards and the mainly Victorian pattern is obvious: 92% of the 9,307 households in E3 live in flats, 8% in houses.
Private renting sits at 30% and owner-occupation at 23%; the first group books pathway jet washing at short notice, the second plans it.
Walls are precast concrete panels and dense blockwork in Bromley-by-Bow, often with surface conduit — where 23% owner-occupation means the same home is booked again rather than a new tenant each year, so the fixing that matters in Bromley-by-Bow is chosen on site — the usual failure here is in E3, drilling blind into a panel with reinforcement or a buried cable behind it — which is why London Borough of Tower Hamlets kerb rules get settled before the van is loaded.
Two streets can behave very differently in Bromley-by-Bow: the Lea navigation, the gasworks site and estates between Bow and the Olympic fringe. The quote reflects the street the job is actually on. Bromley-by-Bow sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Getting to the door matters as much as the job: a12 severance, estate service roads with height barriers and lift-only access in most blocks. Bromley-by-Bow (District, Hammersmith & City) is the nearest station, and one technician for a private path; two where a communal walkway has to stay open to residents while the work is done, so one can manage access while the other washes.
