I'm having a oh ($%&!) crap moment here and looking for help ASAP. After stablizing the living room and starting to install a new vapor barrier, I took a break and have not been at my flip home in a couple weeks. It's been raining non-stop in the area lately, and fearing that the crawl space may be taking on water, I went to check it out. I found that it does has some water in it, plus something nasty black looking stuff growing down there (see photos). Is this stuff black mold? Another type of mold? Something else? I don't know where it came from, but it wasn't there two weeks ago. What can I do to stop this immediately? I was planning on installing a sump pump to get the water out, but apparently I was too late. Thinking I could just pour some liquid bleach in the crawl space to stop what's going on now, but not sure that's the right thing to do. Also have heard a Borax solution can stop growth, but again not sure. One thing I am sure of is I need some help quick!
