Mold is a fungus that grows in multicellular filaments. In order for mold to grow it needs to have a source of moisture. Often this source of moisture in home is a water leak in the plumbing, flood, or natural disaster. To fix your mold problem you need to eliminate the water source needed for it to grow. You also need to hire a professional to clean your mold problem within 24-48 hours.
In the natural environment, mold is beneficial. It breaks down dead organic matter such as fallen leaves and dead trees. Indoors it can create several health problems such as asthma, headaches, sneezing, runny nose, and eyes. Some molds are so toxic that they can be deadly, such as black mold. Indoor molds also destroy anything they grow on. If you want to protect your investment you need mold remediation, removal, and restoration immediately. It is impossible to get rid of all mold and spores indoors since they can be found floating through the air and house dust. They will not grow is there isn't any moisture present.
Professional mold removal is highly recommended to make sure all the mold has been removed, the water source eliminated, and the damaged area restored. A mold test is conducted, then appropriate products applied, while the water source is eliminated. Your home is restored to pre-mold condition.
