If mold is discovered, we will do our best to discern whether the growth is limited to only the wet areas affected by the water loss. Pre-existing mold damage is usually not covered under mitigation costs and will require a separate estimate for removal. If it is a very small area related to water loss, we will try to get approval from the insurance company to treat the area. We will set up a containment, and then we apply an EPA-certified antimicrobial agent to the area to kill the fungal growth, followed by a HEPA vacuum treatment, and in some cases, we'll seal the surface with an approved sealant. If additional growth is found in the dry areas of the home by the homeowner, whether during or after the dry-out, we recommend that you have mold testing done in the home as it is most likely a previous fungal growth present before the water loss occurred. Many insurance companies have their own stipulations regarding fungal growth, and coverage is specific to your own policy.
