The presence of moisture in drywall can indicate potential damage or mold growth. Invasive methods provide accurate readings of moisture levels within the drywall.
Invasive methods involve physically cutting into the drywall to obtain a sample for testing:
Mold growth can occur in drywall at moisture levels above 30%. Accurate measurement of moisture levels is critical for early detection and prevention of mold proliferation.
Invasive methods are recommended when non-invasive methods (such as surface moisture meters) provide inconclusive results or when specific areas of the drywall appear compromised.
The results of invasive moisture testing should be interpreted by a qualified professional. Moisture levels above acceptable thresholds (typically 12-15%) indicate potential damage and require further investigation or repair.
