We just got moved in after a house fire. The fire dept of course left things a "little" damp, and mold was growing beautifully. What the professional folks used, after cleanup with shovels,etc. was ozone generators. They not only took care of mold, but took all the smoke smell out of the place. You can find them on line for about $400, or maybe rent one. The house can not be inhabited while the process is going.
