Water Damage (Pictures included)

[Andrew Jones]

In my personal residence that I own my roommate's bathroom sink on the second floor had a leak that was never attended to (not sure how long it has been because I never go in their and I gave him a months notice to leave right after I found out). The water managed to seep through to the first floor ceiling. The water damage spots on the ceiling are several feet apart. I have the leak under control now, but I am unsure how to proceed in getting the place perfect again. I have a referral to a company called California Restoration (cal-restoration) from my plumber and a company called Servpro from a friend that is an insurance adjuster. Any suggestions or comments on what it might cost? Have you had this happen to you?

I am worried about mold and if it is unhealthy to be around, but I do not visibly see any mold.
