Old upvc porch door dropped advice needed!!

[Chri5hill]

Hi guys
We have recently moved into a property that has a upvc porch door within a upvc archway.it looks like the door has dropped because there is a gap at the top but I've looked at the hinges to see if I can adjust them but don't think you can.i have attached a couple of pics just asking for advise on how to get the door straight again.
Thanks
Chris

The door will need "Toe and Heeling" http://www.glassandlock.co.uk/how-to-toe-and-heel-a-door-or-window/
Basically you need to take the door glass beads out, Lift the door and add some more packers above the glass on the handle side (probably about 5mm by the looks of it).

It looks like your door is externally beaded so you will likely find a removable rubber wedge gasket on the inside that needs to come out before you can get the beads out.
