Hello,
I’m doing some work on a pre-existing extension here in New York and I found a serious draft coming from the window.

When I pulled the trim I found a lot of wood rot and no insulation or flashing. I also noticed the wooden buck extends through the wall and is flush with the exterior stucco wall.

I’ve never seen a window installed like this, from what I know it looks sloppy but don’t have a lot of stucco experience.

So, should I be pulling this all out and reinstalling or can this be salvaged somehow?
