Acceptable moisture levels in walls can vary depending on factors such as the location, climate, and materials used in construction. Nevertheless, it is generally recommended to keep moisture content in walls below 15%. Higher moisture levels can lead to problems such as mold growth, structural damage, and health issues.
To determine appropriate moisture levels for your property, it is recommended to consult with a qualified moisture mapping specialist. They can assess the specific conditions of your structure and recommend appropriate measures to manage moisture levels effectively. Regular moisture mapping is also recommended to ensure ongoing monitoring and maintenance of acceptable moisture levels over time.
