Walk Carshalton from Carshalton Ponds and Honeywood Museum outwards and the mainly Victorian pattern is obvious: 33% of the 9,444 households in SM5 live in flats, 67% in houses.
Private renting sits at 16% and owner-occupation at 76%; the first group books school clearance at short notice, the second plans it.
Walls are solid London stock brick in SM5, 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 on these streets — measured on the walk in from Carshalton (Southern) rather than assumed from a map.
Anyone who knows Carshalton knows the pattern near Carshalton Ponds and Honeywood Museum: spring-fed ponds, a village high street and the Wandle's source. We plan the SM5 visit around it. Carshalton is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: narrow lanes around the ponds with a conservation area; driveways elsewhere. Carshalton (Southern) is the nearest station, and two to four operatives for a single-building clear, scaling to two teams working in parallel where a full primary site has to be finished inside a two-week holiday window.
