Accordingly, how do you seal gaps on a French door?

Align your French doors with the frame. You can do this by tightening the hinges or removing and replacing them. Put adhesive weatherstripping foam around the door frame where the French doors touch. Look for cracks in your door, especially around glass panes, and fill them with caulking.

Subsequently, question is, how much space should be between French doors? So if the doors are 24-inches wide, leave a 1/4-inch gap between doors and between each door and the jamb. And don't forget that the jamb is usually 1-inch thick with another 1/4-inch space between the frame and the jamb. This adds up to a total of 51 1/4 inches for the width of the opening.

Beside this, how do you seal a gap between double doors?
