What's that smell?
While it is possible to visibly see mold on a surface or smell mold in the air, it is not possible to know what’s going on. Just because you are seeing or smelling the mold does not indicate the spores have become airborne. When molds become aerosolized (airborne) the issue becomes much greater because there are then potential personal injury implications as well as substantial contents cleaning recommendations which will need to be followed to remediate the structure.
A visual inspection is an important first step in any microbial investigation. Unfortunately, molds thrive in environments where there is a lack of ventilation such as in wall cavities, sub floors, beneath wall and floor coverings, behind vapor barriers, and above ceiling tiles. Therefore, when microbial growth is suspected it is critical to investigate all areas thoroughly for potential moisture impact.
