Weatherproofing gaps in door corners

As new owner of a 2002-built house with vaulted ceiling and with probably its original weatherstripping, I'm focused on keeping heat inside now leaking through doors at moment. (Spouse mapped what she believes are drafts in all windows & doors).

My present issue is dealing with gaps in the door corners that even fail the can-you-see-light test. Current stripping looks good. It just seems that corners were not tightly done (see photos).

These photos show one of the two French-style exterior double doors on back of house (one at dining area, other master bedroom). Top photo shows knobbed door at door bottom, and middle photo shows gap at top of door on hinge/jamb side, while bottom photo shows that door at the top where it mates with other door. My attempt is to show light eking through.

How can I seal off those corners? Cutting more stripping for the gap? which kind? I am thinking squirting something that turns transforms into compressible insulating foam and sticks to the jamb would work. What online site is good for getting materials? (Home Depot appears to sell Frost King.)

The door bottom seems ok, with the multi-finned shoe-type door sweep.

Later I will try to figure out what to do about the windows

Doors now come with a gasket just for this troublesome area. Search for Door Corner Seal and you will find options for aftermarket seal. They are just a self stick piece of compressible foam designed to close that little gap.

Your door sweep at the bottom can be replaced. They do wear out after awhile. Also the original weatherstripping can be replaced. There shouldnt be that much of a gap in the corners. Looks like normal wear to me.

This is the best kind of door corner pad, it actually goes behind the weatherstrip which helps poof it out a little more. You can install one at each corner. In your case with that giant gap on top, I would also suggest you replace the westherstrip... or at a minimum, remove it and pull it up 1/4" higher. Whoever installed it did a bad job of measuring... or it just shrunk.
