I have more information,
There was a mold even (at the baseboard level) behind the dry. So far the conclusion is that
1. I need to replace door frame
2. Dry wall (portions)
3. Part of Subfloor boards
But what is worrying me the most are 2 main things
1. So when I broke the dry wall at the baseboard level, I saw the frame (which was little moist) and behind that was foam insulation after that a black color plastic sheet. But the thing was that insulation was also wet which concerned me the most.
2. I saw few mold dot on framing. Does this mean that something needs to be done on framing too?
I am concerned whether my insurance will cover any of this or not
