In Carshalton (SM5) the split is 33% flats to 67% houses over 9,444 households, and the stock is mainly Victorian.
Because 16% of Carshalton is privately rented and 9% socially rented, a lot of SM5 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are solid London stock brick; locally that also means some of it dry-lined during a later refurbishment, and narrow lanes around the ponds with a conservation area; driveways elsewhere, so the fixing that matters in Carshalton is chosen on site — the usual failure here is fixings landing in soft lime mortar joints instead of the brick body, as the Carshalton stock goes, where 76% owner-occupation means the same home is booked again rather than a new tenant each year.
Carshalton 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 — spring-fed ponds, a village high street and the Wandle's source — which is why a SM5 quote is not a Sutton average.
On access, narrow lanes around the ponds with a conservation area; driveways elsewhere — one reason two crew and a Luton on most strip-outs; three crew and a tipper where the load is rubble, hardcore or soil and weight rather than volume decides the run.
