- If your reading is over 20%, you may need to replace the drywall entirely.
- The walls in your home with healthy humidity levels should have a moisture reading between 12 to 15%.
At what moisture level does mold grow in drywall
- Mold will grow in your home with humidity levels over 55% or higher.
- Controlling humidity levels with a dehumidifier and good ventilation can help prevent mold growth.
- Dry walls with a moisture level of over 17% may often need to be removed and replaced by a drywall service.
What level of moisture is acceptable
- An acceptable level of indoor humidity is generally 30 to 50%.
- Excess moisture promotes mold, mildew, fungi, bacterial growth, and possibly viruses.
- Contaminants can degrade the indoor air quality and cause health problems.
What is an acceptable percentage of damp in walls
- 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 is a high moisture level in a home
- High humidity can cause problems in your home if relative humidity regularly exceeds 60%.
- Mold and mildew can start to grow when the air contains water vapor above that level.
- Excess moisture can also cause rot, which can damage your belongings.
