  • Structural damage (e.g., warping, rotting)
  • Health issues (e.g., respiratory problems, allergies)
  • Poor indoor air quality

Moisture Detection and Control

Regularly monitor moisture levels in your walls using a moisture meter. If unacceptable levels are detected, promptly identify and address the source of moisture. Employ appropriate control measures such as:
