The company tells me what I need is a crawlspace dehumidifier. They
put down new moisture barrier, seal the vents, install a GFC line,
dehumidifier and pump all for $3000. That does not count spraying for
the wood destroying fungus. The dehumidifier is supposed to dry out
the area so much that all the mold will go dormant.

I think that before I spent all of that money and had all of that done, I
would try just removing the existing insulation from between the floor
joists. The temperatures in Virginia are somewhat moderate, so I don't
think that not having the insulation will cause any issues and there is a
good chance that it will resolve the problem. I would do that and then
check back in a month or two to see what the status of the existing mold is.
My hunch is that it will start to go away on it's own without even having to
pay to have it sprayed with a bleach solution.

Also, by a GFC line, I assume you mean a GFCI line and receptacle. Where
will the water from the dehumidifier go? -- does it get pumped out to the
outside of the home?
