It seems there is condensation building up underneath my house on the
end near the garage that doesn't have foundation vents. Some of the
joists have mold or a fungus on them. The prior owner installed some
crawlspace fans and had them on a timer. I went under there today and
moved one of the fans from under the porch to that wet area and aimed
it toward the other fan that was blowing in the direction of the vents
at the other side of the house. I had to run a new wire from the old
location to the new location of course. I've left the fans on
continuously and will check it in a few days.

The exterminating/moisture inspection company that told me about the
problem has offered a $560 treatment that sprays all exposed wood under
the house and kills any thing that is alive now. I've considered going
under there and spraying bleach/water solution, but I don't think I'll
come out alive.

Does anyone have experience with this?


It would probably help to know where your home is located to get a better
idea of the climate in your area. Also, is there any insulation between the
joists (with or without facing)? And, is it an uncovered dirt floor in the
crawl space, or some other type of floor?

I recently went to a meeting where an inspector talked about this condition.
He suggested no insulation between the joists or, if there is insulation, to
make sure it is unfaced insulation. He said placing 4-6 mil plastic on the
dirt floor can create a moisture barrier to help prevent the moisture in the
soil from coming up. And he said that sometimes no vents are better than
having vents because the warm humid air from outside can come in through the
vents and cause the condensation you are seeing -- especially if there are
fans operating which bring in the humid air.
