Stiff sash lock on a Victorian stone-built terraced house
Common on Victorian stone-built terraced houses across Wakefield — the timber door has moved seasonally and the mortice case has bound against the keep. We often see this coupled with worn mortice locks on Victorian stone terraces in Alverthorpe and Eastmoor requiring replacement. 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.
