Here is what I did today.
This is the exterior wall of a house that has a deck and balcony above that was not installed correctly. This allowed water to enter the wall above and over a few years rot out the framing all the way down.
A former 2 x 4 in the wall.
Inside the wall.
New framing.
This corner of the house goes up 2 stories.
Now that I have the wall a bit more solid I can rip out the damaged sheet rock
in the room without the window falling out.
