The Moisture Evaluation process is the process followed to locate excess moisture in building materials. Once the excess moisture is located, it is then documented and evaluated to create the proper credentials so that the drying and/or removal process can begin. During this process the source of the excess moisture is found and controlled.
The moisture detection process is very important to start as soon as signs are found because moisture on building materials can cause mold formation and eventually structural deterioration. There are many health related risks associated to mold exposure which creates a great importance to solving excess moisture issues as promptly as possible.
The IICRC S500 Standard and Reference Guide for Professional Water Damage Restoration states:
9.4 Inspection Process
The moisture inspection process includes, but is not limited to: gathering information; conducting a survey of the structure including pre-existing damage; performing a moisture inspection and mapping its migration; developing a preliminary determination, and determining the need to involve specialized experts.
9.5.1 Determining the Extent of Moisture Intrusion and Migration
Determining the Extent of Moisture Intrusion and migration requires the use of moisture detection equipment. Since water can flow under walls, and come from above, it is important to inspect adjoining rooms even when no water is visible on the surface of floor coverings.
9.6 Determining the Category of Water
