UNDERSTANDING MOLD

Understanding mold
  • Mold can be harmful or helpful — depending on where it grows.
  • Mold needs moisture to grow.
  • Mold does not grow on dry materials.
  • Mold growing inside a home can affect the occupants.
  • Occupants can learn to recognize mold.

Molds are microscopic fungi, a group of organisms which also includes mushrooms and yeasts. Fungi are highly adapted to grow and reproduce rapidly, producing spores and mycelia in the process.

You encounter mold every day. Foods spoil because of mold. Leaves decay and pieces of wood lying on the ground rot due to mold. That fuzzy black growth on wet window sills is mold. Paper or fabrics stored in a damp place get a musty smell that is due to the action of molds.
Molds can be useful to people. The drug penicillin is obtained from a specific type of mold. Some foods and beverages are made by the actions of molds. The good kinds of molds are selected and grown in a controlled fashion.

Molds are undesirable when they grow where we don’t want them, such as in homes. Over 270 species of mold have been identified as living in Canadian homes. Molds that grow inside may be different from the ones found outdoors

Mold Remediation, Mold Abatement and Mold Mitigation are interchangeable terms that essentially mean fixing a mold problem in a structure. So without further ado, here is Mold Remediation and Mold Removal article here. http://waterdamagerestorationdallastexas.com/tag/texas-mold-inspection/
