Moisture Mapping Acceptable Moisture Levels and Normal Reading for Drywall

Introduction

Moisture Mapping is a reliable method used to identify moisture intrusion and verify the extent of damage within a structure. It involves utilizing specialized equipment to measure moisture content in building materials.

Acceptable Moisture Levels

When conducting Moisture Mapping, specific moisture levels are deemed acceptable within different building materials:

  • Wood: Below 15%
  • Concrete: Below 5% - 8%
  • Insulation: Below 10%
  • Drywall: Below 16%

What is a Normal Moisture Reading for Drywall?

Drywall, a common wall and ceiling material, typically exhibits a moisture reading between 5% and 12% under normal conditions.

Readings above 16% indicate excessive moisture presence, which may compromise the structural integrity of the drywall and necessitate immediate attention to prevent further damage.

It is essential to consult with qualified professionals for accurate Moisture Mapping and interpretation of results to ensure proper remediation and restoration of affected areas.
