Re: How to fix a double door that has shifted during the winter
1 - All doors, particularly wood, will expand and contract with seasonal temperature and humidity changes.

Carefully hand tighten the hinge screws into both the jamb and the door. Lift up on the door as you do to take the strain off the hinge/screws, making them easier to tighten and less likely to strip.
3 - Persistent binding will likely be associated with structural movement. This doesn't necessarily mean you have issues though. In times of dry weather, the ground dries out and contracts. During wet and cold, the ground expands and heaves. All this happens naturally from season to season. Where you can start seeing structural issues is during long periods of either, followed by the other, meaning if you've had 3 dry years and now you're having a wet one, the ground is going to absorb a lot of moisture and heave accordingly. Conversely, if it's been wet a few years and now it's severe drought, you can bet the ground is sinking. This kind of movement will be noticeable in doors throughout the house and likely some cracking walls and possibly foundations.
