Thanks for the opinions everyone!

I had wiped it down with generous amounts of bleach right from the start. I think the wood will be a keeper at this point. Treated it with a mold inhibitor this morning and plan to primer over it as well once it's dried.

I'm going to see if I can find someone to pull the the window and reinstall to make sure the repair is permanent sooner rather than later. Unfortunately I don't have enough hands to try to pull it out myself. But I'd feel much better with a new butyl seal than the thin'ish bead of sealant that's currently keeping water out.
