Harrow's large 1930s mock-Tudor semis around West Harrow and the more compact terraces of Wealdstone need very different lock specifications — our engineers always carry both BS3621 mortice locks and modern multipoint cylinders.
First Line Locksmiths is the call-out locksmith of choice for Harrow households, landlords and small businesses. We cover HA1, HA2 and HA3 — Harrow town centre, West Harrow, Wealdstone, Kenton, Harrow on the Hill and South Harrow — 24 hours a day with an honest ETA given on the call.
Harrow's housing splits sharply by postcode. HA1 (Harrow town centre and West Harrow) is dominated by 1930s mock-Tudor semis on substantial timber doors that still run BS3621 5-lever mortice locks. HA2 (South Harrow, Rayners Lane) mixes inter-war semis with UPVC retrofits from the 1990s — the same stock that's now seeing heavy gearbox failure rates. HA3 (Wealdstone, Kenton, Belmont) is denser, with a mix of post-war terraces, modern flats and large HMO conversions around the station.
Harrow van stock reflects that mix: BS3621 mortice locks (Banham, Chubb 3G110, Union 2C13) in brass and chrome finish for the period semis; Yale Doormaster, GU Secury, Fuhr Multisafe and ERA Vectis multipoint gearboxes for the UPVC stock; full TS007 3-star (Avocet ABS, Brisant Ultion, Mul-T-Lock) cylinder suites for upgrades and burglary repair; and keyed-alike landlord change-over kit for the HA3 HMO market.
