Reviews
What Hounslow customers say
“Snapped the key in the lock on a Sunday morning. Out within the hour, key extracted, new cylinder fitted, and the chap even oiled the hinges while he was at it.”
Eleanor W. · Hounslow · Snapped key · 5 days ago
“We'd just bought the house and wanted every lock changed. One visit, keyed alike, and a proper explanation of what BS3621 actually means for the insurance. Very reassuring.”
Graham T. · Hounslow · Moving house · 2 weeks ago
“Honest to a fault — told me the lock could be repaired rather than replaced and charged accordingly. Rare these days.”
Nadia K. · Hounslow · Lock repair · 3 weeks ago
