Interesting project pictures:
Perhaps the most interesting pictures that we have ever encountered are this "Mushroom like growth" fungus, growing from the bottom of water damaged vanity cabinet. Although walls & wall cavity were treated, no apparent contamination was present on the surface. However, bottom of the cabinet clearly showed early formation of viable fungi.
Example of hidden mold colonizing on the back of the sheet rock board, while the front of the board was unaffected. Cause of contamination was "blow-in" insulation inserted in wet condition (by manufacturer specifications/instructions). Although the developer had properly insulated every apartment unit in this newly re-built development, nobody expected to find heavily contaminated walls. Reason for mold inspection was suspicious moldy smell in every unit.
Another case of "hidden" mold contamination. General contractor had demolished the surface sheet rock board and upon removing the fiber-glass insulation ordered his crew to stop the project. Our inspection showed most possible cause (pictured below), in flooded basement of the same building.
What is really hard to inspect and shows little or no evidence of mold growth (until it is too late), is wall laminates/paneling. In this case, two sets of paneling were installed over the existing sheet rock boards and the occasional "odor" was the reason for the home owner to call us. What we found out is that the source, which was partially flooded ground floor, originated right after 1999 hurricane Floyd.
Contaminated foundation wall in the residence. Pictures of before, during and after the remediation.
Contaminated wall in one of the hotel penthouse rooms. Source: "undetected" roof leakage...
Yet another mold contamination "hidden" behind the wall paper (different hotel). Adjacent wall was the indicator (bathroom leak).
