Mold Develops Because of Water
Attics, crawlspaces, wall interiors, basements, around chimneys--all are places where water can intrude. An excessive amount of humidity in a house can also condense and cause mold.
Environmental experts note that newer homes tend to experience more mold growth than older homes because of the fibrous nature of drywall. Fiberglass insulation, too, provides fertile ground for mold growth.
Mold problems that we see today are problems that we unknowingly created ourselves and they are not problems we had 20 years ago or more. Since 1978 the government has been requiring homes to become more energy efficient in their construction. The more energy efficient they are, the tighter they are sealed up, the less natural breath ability a home has.
According to the Center for Disease Control, if you see or smell mold, there is potential health risk and you should hire a professional mold detection company, like AdvantaClean, for cleanup and removal.
