Local housing stock and what it means for your locks
Harrow housing is broadly 65% inter-war semis, 25% post-war terraces, 10% modern flats around Harrow town centre. Large mock-Tudor semis often have multiple external doors — we routinely fit keyed-alike Mul-T-Lock or ABS suites for these.
Recommended locks for Harrow properties
Avocet ABS, Brisant Ultion 3-star euro cylinders, BS3621 mortice locks for traditional back doors.
Crime and security context
Wealdstone and parts of Kenton see persistent burglary — we strongly recommend Avocet ABS or Brisant Ultion across all external doors. We strongly recommend pairing any cylinder upgrade with an internal deadbolt on rear doors, key-locking handles on ground-floor windows, and a visual review of side and back gates. Every visit includes a free top-to-bottom security review with no obligation.
