In Barnes (SW13) the split is 46% flats to 54% houses over 9,121 households, and the stock is Georgian and early Victorian.
Because 27% of Barnes is privately rented and 16% socially rented, a lot of SW13 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are lath and plaster over timber studs; locally that also means with solid brick on the party and external walls, the reality on the streets around The WWT London Wetland Centre, so the fixing that matters in Barnes is chosen on site — the usual failure here is a plasterboard plug spun into lime plaster in Barnes, which crumbles the key and drops the panel, which is why London Borough of Richmond upon Thames kerb rules get settled before the van is loaded.
Barnes 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 — a village around a duck pond inside a loop of the Thames, with the wetland centre nearby — which is why a SW13 quote is not a Richmond upon Thames average.
Getting to the door matters as much as the job: narrow village lanes, conservation-area limits and Boat Race day closures. Barnes (South Western) is the nearest station, and two to four operatives depending on room count, scaling to a second team on a full-floor or full-closure clearance where the schedule is set by a redevelopment date.
