Mold inside walls usually grows from a hidden leak, condensation or past water damage. Wall mold removal opens the affected wall, removes moldy drywall and insulation, treats the framing and fixes the moisture so the wall can be rebuilt.
Signs include a musty smell near one wall, stains or bubbling paint, and soft drywall.
