My crawl space is damp and am worried about mushrooms comming up and
contaminating the air in the rest of the house , I ve already seen
some
white stuff and am assuming it is mold , what steps should i take to
clear
the matter up, someone told me to spray ant fungal spray on all the
wooden
beams and they to lay down thick plastic all over the floor and walls
of the
crawl space.
Also the ground is sloped to one side of the basement and towards
the sump
pump.

Here are some things to consider:
The surface of the ground around the building should slope so water
runs away from the building.
Water from the roof should be kept away from the building as much as
possible.
The surface of the crawl space should be at the same or higher level as
the ground outside.
If the ground is generally wet in the area, perimeter drains may be
needed to keep the crawl space dry.
Ventilation is needed to keep humidity as low as possible.
6 mil poly sheets should cover the floor of the crawl space. Lap the
edges 4 to 6 inches and seal with mastic. Lap the poly 6 to 8 inches up
piers, pipes and other interruptions and seal.
