First, let's go over a quick review of mold. All molds are fungi, and share biology with mushrooms and lichens, for example. The mold that is dangerous to you and your family is uncommon in the fungi world, meaning most kinds aren't dangerous. However, some toxic molds are dangerous, so any mold you find indoors must be cleaned up and completely removed.
Government experts recommend that you reach out to a Mold remediator company for cleanup help if the mold growth takes up more than about 3 square feet. If you see mold growth, there is probably hidden mold behind walls, in attics and elsewhere.
Check credentials before you hire a mold removal company. The State Office of Consumer Protection is a good place to get started, and you can check for approval by groups such as as the Contractor Connection, Restoration Industry Association and the Institute of Inspection, Cleaning and Restoration.
Mold damage left to grow sends off spores, which fly like dandelion seeds and can harm your possessions very quickly. If not, mold damage will continue to feast on your structure and can destroy your possessions.
