There place is musty and dank and probably some terrible moisture and water damage in the walls.

If the area is not dry when the bleach evaporates, or moisture is still in the contaminated area (humidity, outside air dampness), you could re- start the contamination process immediately and to a greater degree.(9) Chlorine is a key component of DIOXIN.

Forced air is the way to go to prevent stagnant air build up and to prevent mold/moisture problems.

We had a mold inspection done and there seems to be mold and high moisture content in 2 bedrooms, the kitchen and bathroom areas.

Due to this failed communication over the first 2 years of use the floor failed by the front and back door due to moisture getting under the floor where the tenants tracked in snow.

Out here in Reno, NV in most older homes the basement was never meant to be occupied and can be subject to moisture creep, flooding, or mold.  

Hi Everyone, Do you guys know about the best equipment that is not crazy expensive to detect if a wall is humid? Do infra red thermal cameras work for that?Open to any and every suggestions, Thanks in advance! 

Most types of toxic mold develop from a water or moisture source. 

I have, although, seen some laminates that are not very moisture friendly and will swell at the seams over time just from damp mopping and they will scratch rather easily.
