First, let's go over a quick primer on mold. All molds are fungi, and share biology with mushrooms and athlete's foot, for example. The mold that is toxic to people is uncommon in the fungus world, meaning most kinds you find in your house or business aren't harmful. However, some 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 company for assistance if the mold you discover takes up more than 3 square feet. This is because if you see mold growth, there is probably more trapped in drywall and crevices and elsewhere.

Check licensing and certifications before you hire a mold damage cleanup service.

Mold damage left to grow sends off spores, which act like seeds and can harm your possessions very quickly. If not, parasitic fungi will keep eating on your structure and can ruin your possessions. Some types of mold, those that release mycotoxins, can also cause sever health risks ranging from neurological damage to respiratory and mold-related infections and generally poor health. Mold can be especially dangerous for infants, children, and anyone with a compromised immune system .
