Moisture readings above 20% are indicative of a humid environment, which should be addressed to preserve the integrity of the structure as well as prevent the formation of mold, mildew, and other fungal growth.
What is a Bad Moisture Reading?
Moisture readings are used to determine the moisture content within a material or at a given location. Readings above 20% are considered high and indicate a humid environment.
Risks of High Moisture Readings:
- Structural damage due to expansion or warping of building materials
- Mold, mildew, and fungal growth, which can cause health problems
- Deterioration of finishes, such as paint or wallpaper
- Increased risk of wood rot or decay
It is important to note that moisture readings can vary depending on the material being tested and the location within the structure. Factors such as temperature, humidity, and insulation can also impact the readings.
If a moisture reading above 20% is detected, it is recommended to contact a qualified professional to determine the cause and take appropriate action to mitigate the issue.
