In Southfields (SW18) the split is 44% flats to 56% houses over 3,815 households, and the stock is mainly Edwardian.
With 33% private renting against 61% owner-occupied, most SW18 bookings land on a move-in day rather than a weekend.
Walls are solid London stock brick; locally that also means some of it dry-lined during a later refurbishment, and with 24% one-person households in Southfields, one adult is usually the only pair of hands on site, so the fixing that matters in Southfields is chosen on site — the usual failure here is fixings landing in soft lime mortar joints instead of the brick body, as the Southfields stock goes, and with 33% of homes here privately rented, it sets the booking date as often as the job does.
Southfields 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 Grid — a planned Edwardian estate that becomes the Wimbledon gateway each June — which is why a SW18 quote is not a Wandsworth average.
Getting to the door matters as much as the job: championship-fortnight parking bans, narrow Grid streets and permit bays. Southfields (District) is the nearest station, and one technician with a portable extraction machine and air mover on a single household booking; two technicians on HMO, student accommodation and serviced-apartment rounds where six or more mattresses are cleaned in a day.
