Stiff sash lock on a Victorian semi-detached and terraced houses in Birkenhead
Common on Victorian semi-detached and terraced houses in Birkenhead across Wirral — the timber door has moved seasonally and the mortice case has bound against the keep. We often see this coupled with Edwardian mortice lock wear in West Kirby and Heswall properties. The fix is either service (lubricate and adjust) or replace with a BS3621 equivalent if the existing lock is pre-standard.
Our approach Service first if the mechanism is sound; BS3621 upgrade if the existing lock is sub-standard or worn beyond service.
