Classes of Water Damage

The class of damage is important when assessing water damage repair options.

Class 1 is the least harmful form of damage. Materials absorb very little of the water from this type of damage. Water damage repair is the easiest in this type of situation.

Class 2 has a fast rate of evaporation, which means that carpets and cushions may be damaged. Water damage repair is more difficult when it involves class 2 damage.

Class 3 has the fastest rate of evaporation. In this case, the water may come from broken sprinklers or other overhead sources, soaking the walls and furniture.

Class 4 requires special water restoration and water removal procedures. This type of damage may affect hardwood floors, plaster, and concrete.
