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.- Hide quoted text -

Does the moisture barrier include running it up the inside
foundation walls to the sill plate? *That's the premium barrier
and it is a good bit of work to do that. *Just laying out new
pieces of plastic is not much work and a $100 or so fo rthe
plastic. *Ask for the brand/model number of the dehumidifier.
*The price of dehumidifiers varys greatly depedning on what you
are getting. *Heavy duty commercial ones can be over a grand. *So
you need more details to judge the value of their package.

1. *Treat wooden members with fungicide to killl any active fungi.
2. *Sealing all Foundation Vents
3. *Installing Poly Vapor Barrier (100% ground coverage)
4. *Placing a Dehumidifier in the crawl space

That's a pretty expensive dehumidifier so depending on what exactly
they do for he vapor barrier install $3k might not be outlandish. Get
some more details on how they do the vapor barrier.

It seems this option is out. I live in a flood zone and cannot seal my
vents. I will have to look at grading problems and how moisture can be
minimized. Time for someone else to look at the problem.
