Therefore, it is dangerous to gut a moldy house. Mold spores will fly everywhere and you will inhale them. Anyway, we plan to gut the entire house to the poles; my question is if this will go a long way in solving the mold problem. While altering mold will cause an increase in spore concentration and may cause respiratory problems, it should not cause a previously removed stain to magically produce mold.
I would recommend spraying bleach on any area of concern, ventilating the room to the outside with a blower (more air moves than a simple box fan), and using a P100 respirator while spraying or doing a demonstration. Do not apply anything that prevents it from drying inside. If you want to use a fungicide (to kill mold) or a fungistatic (to prevent new breakouts) or even a coat of paint, make sure it's highly permeable to water vapor (with a permanent rating of at least 5, prefer 20 or more). Keep in mind that a flooded concrete slab soaks in water like a sponge.
A wet slab can cause the floor to break and re-moisten the wooden structure. To control the humidity of the slab, use a moisture sensor without pins, if possible. Otherwise, as a rough DIY indicator, tape an 18-inch square clear plastic sheet onto the concrete. Monitor for 24 hours, then, if visible moisture accumulates under the plastic, the slab will still be damp.
If the lining behind the cover is not damaged and is to be retained, the cover must be kept away from the liner to allow air to enter and dry. One way is to cut the cover about 2 inches from the studs, fold the flap until the coating is dry, and then fix it with asphalt-based window tape on both sides of the grooves to restore it. Or, you can trim the top of the cover to clean the back and allow it to dry, but leave 3 or 4 inches to protect the insulation from the water that drains behind the bricks and insert wedges or other spacers between the cover and the liner to allow air to reach the coating during drying. If the damage occurs only to the lower part of a wall, it may be structurally unnecessary to replace the removed brick flanges in some homes (consult a construction professional).
