 Jammed doors opened

Door won’t open? Handle moving but nothing happening? Jammed doors are often caused by uPVC multipoint faults or doors slipping out of alignment. We diagnose the issue, open the door, then deal with the underlying fault so it doesn’t immediately happen again.

Common Jammed Door symptoms:

• Door stuck shut or stuck open
• Handle lifts but won’t lock
• Key turns but nothing releases
• Lock engages intermittently

 Door Mechanism and Alignment repairs

If your door is dropping, catching the frame, or becoming stiff to lock, the fix is often alignment adjustment and/or mechanism repair, not replacing the whole door.

Common issues we fix:

• Door dropping or rubbing
• Stiff handles / stiff locking
• Locking points not lining up
• Mechanism faults affecting smooth operation
