Door dropped, can I adjust these hinges?

[stefan05]

Hi all. I have a composite door fitted in 2017. It's now dragging on the bottom (handle side) making it hard / noisy to open and close. I've adjusted the small grub screw for the bottom hinge (note the one in this picture is the middle hinge)... that has made a difference but I think I really need to move the whole door up slightly. I do have a warranty but can't seem to make contact with the installers!

I'm thinking these are cheap hinges that won't allow me to adjust vertically? Any thoughts on what to do next?

FYI I took the grub screw out completely on that second photo (was ordering some more of them and used that one for reference).

Thanks in advance.

That's great thank you @crank39 ... I've adjusted now. The manufacturer also just sent the instructions... a lot more helpful than the original installers who I can't make contact with.

Door adjusted and all good thanks again.
