Wall Cavity Mold

Can mold contamination inside a wall cavity be identified?Yes.  For example, after a basement has flooded and the water is extracted, the carpet should be removed and the floor disinfected.  However, a mold odor may still be present and the mold source not easily recognizable.  Wallboard, paneling, plaster, wood and insulation that make up the walls in a basement absorbed moisture up into the wall cavity and mold growth resulted.  Wall cavity samples are collected through very small, drilled holes, and analyzed similarly to airborne samples.  Collection of a control wall cavity sample in a wall that was not affected by the moisture is recommended for comparison purposes.
