Types of locks we can repair
SF Locksmiths is able to repair all types of locks fitted to uPVC, wood, composite, aluminium and commercial doors. These include multipoint locks fitted to uPVC and composite doors; mortice sash-locks and deadlocks which are usually fitted to wooden doors; and night-latches fitted on wooden doors as well. We also repair sliding patio doors, specialising in tilt and slide door repairs.
If you have been told that you have a door lock that cannot be repaired or replaced, ring us first before considering a new door.
We do not fit doors and so we are not going to try to sell you a new door. All our repairs and replacement locks come with a 2 year guarantee, the only locksmith company in South Yorkshire to do so.
