Looking for some help with how to correct the sagging going on in our back doors. They are about 12 years old, mahogany veneer over an MDF core, with double glazed inserts that have leaded glass in them. Each door is 36″ x 82″. Plus the doorhandles and locks are pretty robust. So heavy. Over time the door has started to sag and I am not entirely sure why.

Hard to tell for sure whether the doors themselves have sagged, since there appears to be some pincushion distortion in the photo, near the top edge. If the doors themselves have sagged (such that the bottom latch side drags, while the latch side remains parallel to the latch jamb) there's not a whole lot to do other than trim the bottoms a bit to fit.
Frames will tend to sag over time, along the hinge jamb, with the top hinge moving towards the opening and the bottom hinge moving the opposite direction. This can be corrected to a degree by installing long screws in the top hinge screw holes, or, sometimes better, loosening the top hinge and installing long structural screws under it, to pull the jamb towards the rough framing.
But sometimes you need to remove trim and adjust shims on the hinge side.
Also, the hinges themselves sometimes bend, such that the top hinge has more space between the leaves than the bottom hinge. It may help just to swap top and bottom hinges.

Could you take a picture with the camera lens level with the top of the doors/jamb, so we can see that relationship.
Might go straight on for both side jams as well. (show full length).
And, are those Ball bearing hinges?
thanks.
And, get a finish on those beauties b/4 damage is done.

sagging doors
Have you checked to see if the door corners are square (90*)? Put a carpenter's square on the corners. It looks like the doors are now a parallelogram instead of a rectangle with four 90* corners.
The hardware and leaded glass is pretty heavy.
"Pincushion distortion"
Distortion general happens for a number of reasons: using a less than normal size lens, (wide angle), or a cheap lens, are a few.
The simulair effect when photographing a tall building and it appears that it's falling over backwards.
As suggested photographing as straight on as possible with aid in it perspective control.
Well,
It appears that Dan is still in the van.
We could throw several "fixes" at Dan's problem, but none would be more than a WAG. Pity the picture taken didn't show the problem-it might have been easier to come up with the fix.
In the field, that's what would be looked at-current condition. A long level might tell the story if the eye needed reinforcement.
Then again, you probably could use the trial and error method in hopes of correcting the problem.
just a wild guess from a picture.....
Could be a couple good long screws into the top hinges would set that right.
Yep
Or tightening the ones that are there. I do have a hard time imagining that some yokel installed these with out long stud screws in the top hinges, esp for heavy tall doors, but you never know...
