Hello Matthew, did you fix it? I kind of had the same problem with my boat. I have had it for years and I could not let it keep rotting more. I do not know much about this though, so I decided to let the professionals do it. After a brief research online I found an article on the damage control website. They explained how mold appears and how to get rid of it. They advised contacting professionals and I listened to that, that is how I got rid of mold.
