Exposure to mold can cause a variety of health problems and symptoms, including allergic reactions. Mold can be found almost anywhere and can grow on wood, paper, carpet, food and insulation. When excessive moisture accumulates in structures or on building materials, mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed.
In some cases, indoor mold growth may not be obvious. It is possible that mold may be growing on hidden surfaces, such as the backside of drywall, wallpaper, paneling, ceiling tiles, carpets and pads, etc. Mold can also hide in pipe chases and utility tunnels (with leaking or condensing pipes), walls behind furniture (where condensation forms), condensate drain pans inside air-handling units, porous thermal or acoustic liners inside ductwork or roof materials above ceiling tiles (due to roof leaks or insufficient insulation).
