In Dartmouth Park (NW5) the split is 72% flats to 28% houses over 3,395 households, and the stock is mainly Victorian.
With 18% private renting against 45% owner-occupied, most NW5 bookings land on a move-in day rather than a weekend.
Walls are precast concrete panels and dense blockwork in Dartmouth Park, often with surface conduit, and with 18% of homes here privately rented, it sets the booking date as often as the job does, so the fixing that matters in Dartmouth Park is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it, as the Dartmouth Park stock goes, where 45% owner-occupation means the same home is booked again rather than a new tenant each year.
Dartmouth Park sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate. What shapes the job more is the neighbourhood itself — steep Victorian streets between Highgate Cemetery and the eastern edge of Hampstead Heath — which is why a NW5 quote is not a Camden average.
Getting to the door matters as much as the job: steep gradients, resident permit bays and long communal stair runs in the conversions. Tufnell Park (Northern) is the nearest station, and one technician for a standard garden patio or deck; two for a roof terrace or balcony where water has to be carried up by bowser and furniture moved through a lift or stairwell.
