Help me realign my PVC French Door

Hi, I've just noticed our French doors have developed a gap at the top which is wide enough to feel a draft and let water in.

I'm guessing the hinges need to be tweaked to adjust the alignment but I don't know which does what? There seems to be two screws and two Allen key holes on each hinge and there are three hinges.

Any help you could give in terms of what to tighten and/or loosen would be appreciated, or alternatively if it's something best left to the experts let me know?

Photos of the gap and the hinge are attached. Thanks.


Hi,
at the bottom one of the two Allen key holes may be the in & out adjuster (or compression of the seal)

Adjusting the hinges won't help. Needs to and healing(probably) and you need to make sure the handle has been lifted to engage the locks. If it still does not seal you need to pull the keeps in(the bits that the hooks lock into) or turn the compression cams so the handle becomes stiffer when you lift the handle
