Local housing stock and what it means for your locks
Hounslow housing is broadly 40% inter-war semis, 30% Victorian terraces (heavy conversion in TW3/TW7), 30% post-war flats and new-build. Many ex-airline staff homes use older Yale rim latches with no anti-snap protection — we typically pair these with an internal deadbolt upgrade.
Recommended locks for Hounslow properties
TS007 3-star cylinders, Yale Doormaster gearbox replacements, BS3621 mortice locks for back doors.
Crime and security context
Heathrow staff turnover means high tenant churn — end-of-tenancy lock changes are our highest volume job category here. 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.
