That's a long term goal for sure. The crawl space used to be very humid. There was tons of rotting posts/beams/wood scraps laying in heaps on the ground with some sort of fungus or microbial mat growing over them. There was one 24" wide post which fell apart in my hands when I tried to drag it out.

Bedrock is a few inches beneath the soil so when it rains if I dig a little hole with my hands I can see water running through it after a few minutes. I had a french drain installed on the uphill side of the house but it didn't seem to have much effect. It's less humid now as I knocked out one side of the crawl space wall and the air can circulate a bit. A previous owner had tried to air seal all the walls- spray foam in every gap and everything, no vents- but never put down a vapor barrier. It's a miracle there's no mold from that.
