Excess moisture and water damage can lead to mold growth in homes. Exposure to mold can negatively impact an individual’s health, leading to respiratory symptoms and even mold poisoning. If homeowners or property managers suspect mold growth in a building, licensed professionals will take the following steps to remove mold through a process called mold remediation. 

1. Containment and Ventilation

Before beginning the mold remediation process, the mold remediation company will cover the floors and walls with plastic sheeting and run hoses to the mold area. They will then set up ventilation and air filtration devices (AFDs) to keep mold spores from spreading. Opening doors and windows can also help promote air flow. They will also help throw away anything that was flooded and can’t be cleaned or dried completely within a day or two. Mold remediation workers will be dressed in protective gear: head-to-toe white suits, boots, respirators and goggles. 

2. Cleaning and Disinfection

Mold can be killed by spraying it with biocide, fungicide or moldicide solutions. All of these solutions are effective in killing mold. Bleach, however, is not approved by the EPA for killing mold. Once sprayed, the mold-killing solution is left to do its work for about a day.

3. Addressing the Source

A professional mold remediation company should also take the necessary steps to identify the cause of mold growth and prevent future mold growth. If, for example, the home has water leaks, high levels of humidity, poor ventilation or a malfunctioning HVAC system, the mold remediation professionals should recommend an effective solution. 

4. Encapsulation

The final step in the mold remediation process is spraying the area with a paint or whitewash to encapsulate the remaining mold spores. This is done to prevent further mold growth. If a portion of the attic has mold growth, then the entire attic should be sprayed to prevent the mold from spreading. Homeowners and property managers should communicate with the mold remediation company to make sure they do this.
