In Colliers Wood (SW19) the split is 67% flats to 33% houses over 4,286 households, and the stock is mainly Victorian.
Because 44% of Colliers Wood is privately rented and 9% socially rented, a lot of SW19 work is agreed with a landlord or managing agent rather than the person opening the door.
Colliers Wood substrates run to with solid brick on the party and external walls — and lath and plaster over timber studs, which is why London Borough of Merton kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster; locally that also means which crumbles the key and drops the panel, and with 44% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a SW19 customer twice.
Colliers Wood 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 — the Wandle trail, Merton Abbey Mills and big-box retail on the High Street — which is why a SW19 quote is not a Merton average.
Getting to the door matters as much as the job: high Street red route, riverside estate roads and new blocks with booked lifts. Colliers Wood (Northern) 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.
