Stiff sash lock on a Victorian stone-built terraced houses in pit village row
Common on Victorian stone-built terraced houses in pit village rows across Barnsley — the timber door has moved seasonally and the mortice case has bound against the keep. We often see this coupled with 5-lever mortice lock failures on Victorian pit-row terraces with thick stone doorsteps. 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.
