The extent of water damage can be determined through a visual inspection as well as through testing. A visual inspection can help identify areas where water has come into contact with materials, such as drywall, wood, or carpet. Staining, warping, and other visible signs of damage can help indicate the extent of the water damage. Testing can also be used to determine the extent of water damage. For example, moisture meters can be used to measure the moisture content of materials to help determine the level of saturation. Thermal imaging cameras can be used to identify areas of moisture that may not be visible to the naked eye. Once the extent of the water damage has been determined, a plan can be developed to repair or replace damaged materials. In some cases, it may be possible to repair water damaged materials, such as by drying out and cleaning affected areas. In other cases, it may be necessary to replace materials, such as when they have been severely damaged or have become contaminated with mold.
