Common window faults we fix
- Handle turns but the window stays shut: usually a broken gearbox or locking strip
- Window won’t lock or the key is lost: replace the locking handle
- Window drops or won’t stay open: worn friction hinges (friction stays)
- Draughts at the frame: adjust the locking cams and keeps
You rarely need a new window. In most cases a replacement handle, gearbox or hinge has it working again the same visit.

What neighbours say about David
Most new customers come from a neighbour, a neighbourhood watch group or another trade. Read every review on Google and Trustpilot.
Dave is an absolute legend. Went above and beyond to fix my door. Highly recommend.
Knowing that finding a qualified locksmith can be like the wild west we asked our neighborhood watch for recommendations. Accredited Locksmiths were recommended by three people. David was a true professional and spent over two hours sorting out quite a complex issue with our door lock.
This company was recommended to me by Timpsons. Booked an appointment, arrived on time and carried out the work quickly and efficiently.
