Finchley Central (N3) is at the north-western edge of my service area, a 22-minute drive from my Tottenham base on a good run, door-to-door times of 30 to 40 minutes. I’ll confirm honestly on the phone whether N3 is realistic for the time you need, and for planned (non-emergency) work, daytime is the sensible slot.
The housing through most of N3 is classic interwar suburbia, 1930s semi-detached three-bedroom family homes off Nether Street and Hendon Lane, with substantial timber front doors and the original ironwork often still in place. Along Ballards Lane and Regents Park Road you’ve got Edwardian terracing, slightly older two-storey stock with bay-fronted entrances and the classic mortice-plus-night-latch combination still doing its job a hundred years later. Near the station there’s a layer of mansion blocks, four and five storey interwar with shared communal entrances and individual flat doors inside. Most of the suburban front doors carry a 5-lever BS3621 mortice and a Yale night latch, with a back door that’s typically been replaced with a UPVC multipoint at some point in the 1990s or 2000s.
The three calls I get most often in N3 are original mortice servicing on the older semis, UPVC gearbox replacements, and occasional anti-snap cylinder upgrades on composite doors. The interwar mortices generally pay to be serviced rather than replaced, the cast-iron case is sound and another twenty or thirty years of life is realistic with a clean and a regrease. UPVC gearbox failures are the standard pattern, handle lifts but the hooks won’t engage, and I carry the common Yale, ERA and Fuhr replacement gearboxes in the van for a same-visit fix. Anti-snap cylinder upgrades to BS Kitemark 3★ come up when a homeowner has installed a composite front door and wants the cylinder brought up to standard, flat £120 fitted.
