What happens if drywall gets rained on?
While drywall is pretty sturdy, when it’s exposed to water for too long it can get damaged. It may lose its structural integrity, becoming soft and weak. Depending on what category of water drywall is exposed to, and how wet it got, you may be able to save it. Speed is critical to avoiding mold damage, though.
How do surveyors check for damp?
Mortgage surveyors will check properties for rising damp with a damp meter and will look for any signs of penetrating damp too. They will also be checking for any signs of damp caused by plumbing related problems as a result of leaking water or drainage pipes.
How accurate are pinless moisture meters?
Surface moisture can also be a problem for pinless meters. For example, when the wood has a small amount of condensation on it, a pinless meter might detect a moisture measurement range from 10-20% higher.
What is an acceptable percentage of moisture for drywall?
Most houses have varying levels of humidity up to 50%, so moisture levels in drywall can vary from home to home. While relative humidity can have some effect on moisture levels, drywall is considered to have an appropriate level of moisture if it has a moisture content of between 5 and 12%.
What level of moisture is acceptable?
A range of 5 to 12 percent is considered optimal. A reading of up to 17 percent is generally considered moderate moisture and acceptable. Any reading over 17 percent is considered to be an indication of saturation and the need to replace the drywall and to take preventative measures against future moisture buildup.
