The major clean up first, you still have wood forms around some concrete, that should not be there and the dirt need so to smoothed out if not levelled before poly is put down and sealed around obstacles and walls.

How old is this house? Looks like rough-cut lumber. Nothing wrong with it. Just interested.

For the water you really need a drain system around the perimeter, some inches lower than the dirt inside.

Re: Flooded crawl space after heavy rain insulation damage?


Are there spray foam insulation kits safety concerns

If I wanted to pick up a kit and do it myself...I found this off the interwebs.

"homeowners who are exposed to isocyanates and other spray foam chemicals in vapors, aerosols, and dust during or after the installation process "run the risk of developing asthma, sensitization, lung damage, other respiratory and breathing problems, and skin and eye irritation."

Treat any mold that may have grown on any wooded area with a solution of water and bleach.
This is all good information. Except for the water and bleach. Bleach doesn't do much against mold on porous materials. It works great in the kitchen and bathrooms where hard surfaces are abundant.

Get a product designed for Mold Removal on all surfaces. There are several out there. Concrobium is one of the major names in mold remediation.

As others have said, first correct where the water is coming from. Otherwise anything else you do is moot. (You can take all of the insulation out, not just what looks wet. Get it ALL out as mold has probably already taken root) This goes for any standing water and the dirt that came with it. Who knows what is in the dirt.

Once the source of the water intrusion has been taken care of, dry it out. Use fans, dehumidifiers, etc.. You can get a dehumidifier with a pump so that it can pump the water it collects to a sump or outside the house.

As it is drying, you can spray all the areas to kill the mold and prevent it from coming back. This means the concrete, wood, metal, everything. Mold can grow on most anything as long as it has moisture and food. Even on metal if it has something on it that the mold likes.

Once the mold killer has been applied according to directions, then you can put in new insulation. Consider using Mold and mildew proof insulation like rock wool (mineral wool) insulation. It is also fire proof.

Tuck those flex ducts (don't know if sag or clearance routed) and wires tight to the joists then you can deal with the insulation.
Surprisingly I don't see any evidence of mold...
