What is a safe level of moisture in drywall
Generally speaking, for drywall, a safe moisture content (%MC) would be less than 1% MC. Anything above 1% MC in drywall would indicate a level of moisture that could compromise the integrity of the gypsum board.

What if drywall is 20% moisture
The rule of thumb is that any moisture reading over 16% is considered damp and needs attention. If your reading is over 20%, you may need to replace the drywall entirely. Walls in homes with healthy humidity levels typically have a moisture reading between 12-15%.
What is an acceptable moisture readings
You should be aware that a moisture reading of 0-15% is quite normal and gives no cause for concern. However, moisture readings in excess of 15% indicate the need for further inspection. Levels between 25-30% indicate that there may be water ingress, meaning that remedial work could be required.

What moisture level does mold grow

What is considered dry on a moisture meter
In drier conditions, 4% MC is considered "dry". In Desert conditions generally, 3.5% is considered "dry". These numbers are %MC numbers on our Concrete Moisture Meters that are Calibrated specifically for concrete based on Gravimetric testing.
Do moisture readers detect mold
Because mold often grows where moisture is high, a moisture meter can help an investigator locate hidden areas of mold growth. The use of personal protective equipment (PPE) should be considered during a mold investigation.
Does moisture in walls mean mold
If left unchecked, minor moisture pockets and damp areas within wall and home structures can quickly allow harmful mold growth, which greatly affects the value of a property and the safety of persons in that property.
How long before mold grows on drywall
24-48 hours
mildew and mold will develop within 24-48 hours of water exposure. Even worse, it will continue to grow until steps are taken to eliminate the source of moisture, and effectively deal with the mold problem. Use the diagram on the facing page to assess the extent of mold in your home.
Will mold always grow on wet drywall
So, Does wet drywall always mold Well, Once drywall comes in contact with water, there is only a tiny timeframe available to salvage it before the mold or mildew begins to set in the wall. Some mold spores can germinate after just 12 hours of drywall being in wet conditions.

How much moisture is too much in a house
Research from the Building Science Corporation found that humidity of 70% or higher adjacent to a surface can cause serious damage to the property. The Health and Safety Executive recommends that relative humidity indoors should be maintained at 40-70%, while other experts recommend that the range should be 30-60%.
What moisture level can mold grow
If there are no cold-condensing surfaces and the relative humidity (RH) is maintained below 60 percent indoors, there will not be enough water in those materials for mold to grow. However, if the RH stays above 70 percent indoors for extended periods of time, mold will almost certainly grow.
What is the normal moisture level in a house
Both winter and summer levels fall within the 30-60% range, with a 10% variation at the appropriate end of the scale: Optimal indoor summer humidity levels: 40-60% Optimal indoor winter humidity levels: 30-50%
How accurate are moisture meters
A high-quality moisture meter used on the right material can be accurate to within less than 0.1% of the material's moisture content by weight. However, a low-end moisture meter can be wildly inaccurate.
Will mold go away if moisture is removed
The mold spores will not grow if moisture is not present. Indoor mold growth can and should be prevented or controlled by controlling moisture indoors. If there is mold growth in your home, you must clean up the mold and fix the water problem.
