LARGEST GAP IS 1/2"
The door doesn't seal well and has been bothering me since we moved in a couple of years ago. In the afternoon, I can feel the heat coming through some of the worst parts of the poorly-installed door. From the outside, with music blasting, I can hear a major difference when I pull the door hard toward me, connecting the seal more fully.
This door is redundant - it has been used ZERO times since we've moved in. We use the sliding door to access the deck. When this section of the house was added by the previous owners (living room over garage), it's almost as if it was an afterthought.
What's the best way to semi-permanently seal it.
If we ever do a major renovation, it'll likely be replaced with just a window, though I'll likely be too cheap to actually opt for that if I can seal it off well enough!
Here are the pics. I didn't clean, because, well, I've got a lot more going on than needing to pretend my house is actually ever cleaner than it looks in these pics!
