When your house floods, the water can damage the structure of the house, your personal belongings, and the health of the inside environment. Flood waters contain many contaminants and lots of mud. High dollar items can get ruined all at once, even with just an inch of water, for example: carpeting, wallboard, appliances, and furniture. A more severe storm or deeper flood may add damage to even more expensive systems, like: ducts, the heater and air conditioner, roofing, private sewage and well systems, utilities, and the foundation.
