Turnpike Lane (N8) is about 6 minutes from my Tottenham base, typically 12 to 22 minutes door-to-door via Wightman Road. The Ladder (the grid of terraces off Wightman Road) is mostly Edwardian stock converted into flats, so shared-entrance cylinders and rekeys for incoming tenants are the two most frequent jobs here.
The Ladder runs as a tight grid of Edwardian terraces between Green Lanes and Wightman Road, two and three storey, and the vast majority of those houses have been split into upper and lower flat conversions over the last few decades. That gives you a shared entrance door at street level with one cylinder serving multiple tenants, plus individual flat doors inside, often with their own mortice and night latch combination. Above the parades on Turnpike Lane and West Green Road you’ve got period flats over the shops, and around the station there’s a mix of council blocks and private flat developments adding more shared cylinders into the mix.
The three jobs I get called to most often in N8’s Turnpike Lane end are communal-entrance cylinder wear on Ladder conversions, renter-turnover rekeys, and snapped keys in tired night latches. The communal cylinders take a hammering, four sets of tenants going in and out daily means the wafers wear faster than they would on a single-occupant door, and a fresh replacement every five or six years is normal. The rekey work tends to cluster, when a landlord turns over an HMO between tenants I’ll often do three or four cylinders on a single visit. Snapped keys in night latches happen because the internal spring weakens with age, the tenant pushes harder, and eventually the key shears, spiral extraction saves the lock body almost every time.
