Black under window and loose masonite

[Diman]

Yes, I understand that...
The house is from '68 so...
I've been to the metalworker in the village and got window sills made that I'm installing today.
But is it enough, as there's only a week left until I (according to my schedule) insulate and place a vapor barrier, then it will be enclosed?

So, I'm thinking:
Window sills are installed today, sealing around the window frame on the outside.
Scrape and treat the masonite and the studs with Mold-Free and let it dry for a week, then in with insulation and vapor barrier.
I’m open to tips on additional measures.

After you've installed the window sills and sealed them, you could always use a water hose to simulate heavy rain against the facade to see if it holds up? It might be a really bad idea, but I probably would have tried it

Not a bad thought actually! Thanks!
