Moisture readings can vary depending on the material being tested, but a general rule of thumb is that anything above 16% moisture content is considered high. This level of moisture can lead to mold growth, which can cause health problems and damage the insulation material.
* Musty odor
* Visible mold
* Condensation on surfaces
* Sagging insulation
* Dampness to the touch
The best way to fix high moisture levels in insulation is to identify and fix the source of the moisture. This may involve:
* Fixing leaks in the roof or plumbing
* Improving ventilation in the attic or crawl space
* Installing a dehumidifier
If the source of the moisture cannot be identified and fixed, the insulation may need to be replaced.
