In Clapham Junction (SW11) the split is 74% flats to 26% houses over 4,196 households, and the stock is mainly Victorian.
The renter-heavy mix here (39% owned, 42% privately rented) means a SW11 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Expect with solid brick on the party and external walls, over lath and plaster over timber studs, the pattern behind 4,196 households inside the SW11 neighbourhood behind the plaster in SW11. That is why fixings are picked in the room rather than off a van shelf, and why a plasterboard plug spun into lime plaster in Clapham Junction, which crumbles the key and drops the panel, the reality on the streets around Clapham Junction station and Northcote Road is the fault we are called back to undo.
Clapham Junction 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 — britain's busiest interchange, St John's Hill and the streets between the commons — which is why a SW11 quote is not a Wandsworth average.
Getting to the door matters as much as the job: very tight CPZ, narrow streets with parked cars both sides and no rear access. Clapham Junction (Overground, Southern, South Western) is the nearest station, and one technician with a portable extraction machine — the standard kit for London flats, where a truck-mount hose cannot reach a fourth floor.
