Composite Door - Dropped On One Side

[craig1234]

I've just bought a second-hand composite door which has dropped on one side (catching at the bottom).
I've had an initial play with the hex screws and think I understand what does what. The door margins vertically are not too far off but I can't seem to be able to raise the door on the non-hinged side sufficiently to stop it rubbing (I can lift the door on the hinged side so that it almost touches the top of the frame). My thoughts are that either the frame itself is not true or I need to try and push the door out at the bottom to lift it which will then put the vertical alignment out.
I've attached some photos - apologies that the quality is not brilliant.
Any ideas?

As the gap on the hinge side looks even it seems probable that the frame is not square. Do you have a large square to check it? Alternatively measure the frame diagonals to see if they are equal. It appears to me that the bottom of the frame needs lifting on the hinge side to allow the frame to drop on the lock side.

Thanks for the reply.
I had a quick check with a large square and I think the top is slightly out. I realise now that I should have checked all four corners (I just did the non-hinge side) plus measure the diagonals - I'll try and do this tomorrow.
Is it possible to remove the adjusting screws, pack the door so that at least it doesn't rub and then replace the adjusting screws?

Essentially your frame is fitted out of square to the door like this, obviously I've exagerated it to show what I mean

Thanks Crank39. At the moment the door and frame are just free standing so I guess that may indicate that the frame is out of square as it doesn't have any pressure exerted onto it. As I mentioned, I purchased the door second hand so perhaps it was installed badly and has adopted this shape. I guess when I fit it, I need to put some packers in to try to square it back up. In my reply above, I said that tomorrow I would try to confirm if the frame definitely isn't square by taking more measurements.

The door itself will be square so just pack the frame to suit the door and get the gaps equal , shouldn't need to do any diagonal measurements

Ok thanks for that - makes sense. Won't be installing until after Christmas but I'll report back when I do.

 

[craig1234]

Just thinking about the installation - how should I go about it? Get the bottom level and then pack the sides? If so, where should I pack if the door has dropped as it has?

You need to pack under the frame on hinge side to lift the door OR pack the locking side down. But it's not installed yet anyway so the frame is all over the place right now
