Moisture readings above 700% indicate a very hazardous moisture environment. Such readings typically result from a severe water intrusion event, such as a broken pipe or flooding, and require immediate attention to prevent further damage.
What is a Bad Moisture Reading?
Moisture readings are typically measured using a moisture meter, which detects the amount of moisture present in a material. Moisture readings are expressed as a percentage of the material’s weight. A reading of 100% indicates that the material is fully saturated.
A moisture reading above 15% is generally considered to be high. Readings in the range of 15-20% may indicate a minor moisture issue, such as a leaky faucet or condensation. Readings above 20% indicate a more significant moisture problem that requires immediate attention.
Hazards of High Moisture Readings
High moisture readings can have several negative consequences, including:
- Mold growth
- Wood rot
- Structural damage
- Health problems
Mold growth is a particular concern in areas with high moisture readings. Mold can cause respiratory problems, allergies, and other health issues. It can also damage building materials and furnishings.
Remediation
Remediating high moisture readings requires addressing the source of the moisture. This may involve repairing a leak, installing a dehumidifier, or improving ventilation.
Once the source of the moisture has been addressed, the affected area should be dried out. This can be done using fans, dehumidifiers, or professional drying equipment.
