Mold can form quickly and get out of control because of damp areas, flooding, sewage backup, leaking roofs, damaged pipes, excess humidity caused by a faulty air exchange system, etc. Molds survive in damp or wet environments. It can be found on the outside of walls, behind walls, within a shower, inside the ventilation system, and inside an attic. This mold can be structurally damaging to your home or business. When mold spores are present in abnormally high volumes, they can present especially hazardous health risks to humans and pets. After prolonged exposure, you can experience allergic reactions or more serious health conditions.
