Moisture Mapping A Comprehensive Guide to Acceptable Moisture Levels

What is Moisture Mapping?

Moisture mapping is a process of measuring and documenting the moisture content of a building or structure. It is used to identify areas of excessive moisture that may lead to mold growth, structural damage, or other health hazards.

Acceptable Moisture Levels

The acceptable moisture level for a building or structure varies depending on the material and the location. However, as a general rule, the following moisture levels are considered acceptable:

  • Wood: 6-12%
  • Concrete: 3-6%
  • Drywall: 0-10%
  • Carpet: 40-60%

What is an Acceptable Damp Reading?

A damp reading is a measurement of the moisture content of a material. An acceptable damp reading varies depending on the material and the location. However, as a general rule, the following damp readings are considered acceptable:

  • Wood: 15-20%
  • Concrete: 10-15%
  • Drywall: 10-15%
  • Carpet: 60-80%

If the moisture content of a material exceeds the acceptable level, it is considered to be “damp”. Damp materials can lead to mold growth, structural damage, and other health hazards.
