Moisture mapping is the process of measuring the moisture content of a material, such as drywall, to assess its condition and identify any areas of concern, such as leaks or water damage. Acceptable moisture levels for drywall can vary depending on the specific application and environmental factors. ### What is a Normal Moisture Reading for Drywall? Typically, acceptable moisture levels for drywall are below 15%. Ideally, it should be around 5-10%. Moisture levels above this threshold can indicate the presence of water damage, poor ventilation, or other issues that may require attention. If you have concerns about the moisture levels in your drywall, it is recommended to contact a professional for a thorough inspection. They can use specialized equipment to measure the moisture content accurately and provide guidance on any necessary remediation measures.
