The NW9 stock around The former Hendon Aerodrome and Colindale Gardens is inter-war. ONS records 80% flats, 20% houses and 7,659 households in Colindale.
Owner-occupation runs at 32% in Colindale, so alongside the 35% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are often with surface conduit — and precast concrete panels and dense blockwork — and with 35% of homes here privately rented, it sets the booking date as often as the job does, so the fixing that matters in Colindale is chosen on site — the usual failure here is in NW9, drilling blind into a panel with reinforcement or a buried cable behind it — measured on the walk in from Colindale (Northern) rather than assumed from a map.
Two streets can behave very differently in Colindale: the fastest-growing new-build district in north London, around the old aerodrome. The quote reflects the street the job is actually on. Colindale 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: every new block requires booked goods lifts and loading bays; estate roads are gated. Colindale (Northern) is the nearest station, and one fitter for a floating fit in a single room; two for glued or secret-nailed floors and any job over 25m² in a day.
