With all the rain we've had this season, it's no wonder clients are calling us this winter about mold issues with their properties. In this case, a tenant phoned her landlord complaining of mold growing on her contents being stored in her bedroom closet.
The landlord contacted us for a moisture inspection of the property. When we inspected it we found no active water sources, but the humidity in the house measured around 74%.
To avoid mold issues, the EPA recommends you keep humidity levels below 60%, preferably between 30% - 50%.
In the case of old homes that may not contain insulation in the walls, running a dehumidifier can go a long way as a temporarily measure to prevent mold.
