In Stanmore (HA7) the split is 43% flats to 57% houses over 6,351 households, and the stock is post-war.
With 24% private renting against 61% owner-occupied, most HA7 bookings land on a move-in day rather than a weekend.
Walls are timber stud partitions inside in Stanmore, cavity brickwork outside, measured on the walk in from Stanmore (Jubilee) rather than assumed from a map, so the fixing that matters in Stanmore is chosen on site — the usual failure here is a four-hole bracket with two screws in a stud and two in fresh air, as the Stanmore stock goes, where 61% owner-occupation means the same home is booked again rather than a new tenant each year.
Stanmore 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 — hilltop suburb of large detached houses, the country park and Bentley Priory — which is why a HA7 quote is not a Harrow average.
On access, long private drives and gated entrances; steep hill roads towards the common — one reason two cleaners for a flat, two to three for a house, working together in one visit rather than spreading the job across days. Fitters travelling in use Stanmore (Jubilee).
