Walk Walworth from East Street Market outwards and the Georgian and early Victorian pattern is obvious: 89% of the 7,263 households in SE17 live in flats, 11% in houses.
30% of households rent privately and 22% own, which is why patio and decking cleaning demand here peaks around tenancy changeovers and completion dates.
Walls are precast concrete panels and dense blockwork; locally that also means often with surface conduit — where 22% owner-occupation means the same home is booked again rather than a new tenant each year, so the fixing that matters in Walworth is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — measured on the walk in from Elephant & Castle (Northern, Bakerloo) rather than assumed from a map.
Two streets can behave very differently in Walworth: east Street market, Georgian terraces at Walworth Village and the Aylesbury regeneration. The quote reflects the street the job is actually on. Walworth 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: market-day closures on East Street, estate service roads and single-lift blocks. Elephant & Castle (Northern, Bakerloo) is the nearest station, and one technician for a standard garden patio or deck; two for a roof terrace or balcony where water has to be carried up by bowser and furniture moved through a lift or stairwell.
