What Should Moisture Readings Be for Internal Walls?

Moisture readings for internal walls are essential in determining the presence of moisture issues that can lead to structural damage and health problems. Different materials have varying acceptable moisture content levels:

  • Gypsum wallboard (drywall): Less than 15% moisture content
  • Plaster: 0-2% moisture content
  • Wood studs: 5-10% moisture content
  • Insulation: Less than 6% moisture content

Exceeding these levels may indicate moisture intrusion, water leaks, or inadequate ventilation. Moisture readings are usually taken with a moisture meter, which can be invasive (requiring drilling) or non-invasive (using sensors). Invasive methods provide more accurate readings.

Elevated moisture levels can cause various problems, including:

  • Mold and mildew growth
  • Rotting and deterioration of building materials
  • Structural damage
  • Health issues (e.g., respiratory problems, allergies)

Therefore, it is crucial to monitor moisture levels in internal walls regularly to identify and address potential moisture issues promptly. Regular inspections and repairs can help maintain a healthy indoor environment and prevent costly damage.
