In Hampton and Hampton Hill (TW12) the split is 38% flats to 62% houses over 5,132 households, and the stock is Georgian and early Victorian.
The owner-occupier-led mix here (65% owned, 19% privately rented) means a TW12 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are some of it dry-lined during a later refurbishment, over solid London stock brick, which is why London Borough of Richmond upon Thames kerb rules get settled before the van is loaded, so the fixing that matters in Hampton and Hampton Hill is chosen on site — the usual failure here is fixings landing in soft lime mortar joints instead of the brick body, as the Hampton and Hampton Hill stock goes, which is what a 38% flat share across the ONS neighbourhood covering Hampton and Hampton Hill actually produces.
Hampton and Hampton Hill 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 — riverside village near the palace, with the park and reservoirs behind — which is why a TW12 quote is not a Richmond upon Thames average.
Getting to the door matters as much as the job: riverside lanes are narrow and flood-prone; driveways elsewhere. Hampton (South Western) 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.
