The Alexandra Palace side of N22 (the roads above Wood Green toward Ally Pally itself) is 10 minutes up and across from me, typically 18 to 28 minutes door-to-door depending on how Muswell Hill Road is flowing. Dukes Avenue and the streets off Alexandra Park Road sit behind the park, so most of my run-in is up through Wood Green and across, which is fine outside school-run windows but slows down sharply at 8.30am and 3.15pm. I plan around that on the phone before I commit to a time.
The housing here runs to larger Edwardian and interwar family houses, the kind with solid hardwood front doors and original brass hardware still in use, alongside postwar infill around The Campsbourne and a handful of period flat conversions on the higher streets. On the family homes I work on, the original five-lever mortice is usually paired with a Yale night latch fitted in the 1980s, and almost always the mortice itself is in better shape than the night latch. These older mortices are worth servicing rather than ripping out, the case is heavier, the levers are deeper, and a clean and re-lubricate buys you another decade.
The most common job I get out to Alexandra Park Road and The Avenue is a 3 star anti-snap cylinder upgrade on a composite back door, usually after the homeowner has read up on snap attacks. Lockouts tend to follow a school-run pattern, the door pulled shut on the latch with the keys still on the kitchen table during the morning rush. On those calls I open non-destructively in most cases, which keeps the original Yale alive and saves the cost of a new lock on top of the call-out.
