Stiff sash lock on a Victorian brick terraced houses in the town centre and Westgate
Common on Victorian brick terraced houses in the town centre and Westgate across Ipswich — the timber door has moved seasonally and the mortice case has bound against the keep. We often see this coupled with five-lever mortice lock wear on Victorian terraces in Westgate and St Helen's. 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.
