What Are the Classes of Water Damage?
While categories refer to contamination, classes measure the extent of damage and the rate of evaporation. This information helps us develop a restoration plan tailored to your specific situation.
Class 1: Minimal Damage
- Affects only a small area or minimal amount of porous materials (e.g., carpets or drywall).
- Little to no moisture absorption into walls or floors.
Class 2: Significant Damage
- Affects an entire room or large areas.
- Moisture has seeped into walls, flooring, and structural materials.
Class 3: Extensive Saturation
- Water has saturated ceilings, walls, floors, and insulation.
- Typically involves significant damage from overhead leaks or severe flooding.
Class 4: Specialty Drying Situations
- Involves materials with low porosity, like hardwood, concrete, or plaster.
- Requires specialized drying equipment and techniques.
At K.O.S. Restoration, we use advanced tools like moisture meters and thermal imaging to assess the class of water damage accurately. This allows us to provide effective, efficient water damage restoration services, saving you time and stress.
