Hi,
Good venting. Forced air in/out by a fan?

I'll second the venting. It shouldn't take too long.

I bought this house two years ago with a soupy crawlspace, mainly caused
by a hole in the wall caused by roots, hidden behind a large plant. I
waterproofed the outside, put a layer of vinyl on it, and let it air. I
just used a $10 Wal-Mart fan. One day I blew in, one day out. This
made sure it sucked where it wouldn't blow, and then blow where it
wouldn't suck, if you know what I mean. It took a while, but it's dry now.

It had to have been wet for years. The floors in the house are uneven,
probably caused by wetness under floor supports. Get yours before this
happens.
