Mold concerns

First of all, hello everybody, I'm impressed and happy to find such an intelligent community here. Relieved more than anything. Anyway, I've been doing my research and have an excellant room where i'll be able to house a rubbermaid build. Recently, our room has had some flooding issues, especially mentioned closet. I think the plumbers have fixed the problem, and flooding shouldnt be a problem. I'm much more worried about mold and fungus. I was planning on bleaching the shit out of every inch of the closet, and then getting some sort of fungacide. Any reccomendations?

Edit- Exactly how difficult is it to eradicate mold? I'd like to do as thorough a job as possible to sanitize the closet, and not fuck up the plants.
