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?

Double doors often require a hardware device known as an "astragal." The astragal helps seal the gap between pairs of doors, and is used to block sound or air drafts. Before you install an astragal, you must first determine how your doors are configured, as well as what size astragal you need to use.

How much gap do you leave between double doors?

AWI suggests 1/8" in 2" bevel on the door edge. I think that amounts to a 2.5 to 3 degree bevel. As to the gap issue, if they are exterior doors, you are going to need some type of astragal - either "T" or flat - to help seal out the elements. The gap itself should be about 3/32.

Why does the top of my door stick out?

Let's say the door is out on the top latch side (sticking out on the top, beyond the jamb). To fix this you need to move the bottom of the opposite side (the hinge side) out in the same direction as the door is sticking out. This will push the top of the door inward. Close the door and check for fit to the stop.
