What are the Classes of Water Damage?

Water damage can be of various types based on the type of water as well as the duration that water is allowed to stand on the property. The types are categorized into different classes of water damage.

Classes of Water

In this respect, the type and source of water damage dictates the nature of the damage and its consequential permanence. Typically, there are three water damage categories, with damage caused by the following three types of water:

Classes of water damageClean Water

Water damage caused by this type of water is known as category 1 water damage. This type of water does not pose a health threat to occupants but can still damage property and belongings quickly.

In many instances, clean water damage can be caused by a crack or leak in the home’s water supply line, an overflowing sink, or tub without any contaminants or malfunctioning appliances.

Weather factors like rainwater or melting ice that has not contacted soil or other components, and broken toilet tanks that do not contain any additives or pollutants can all cause category 1 water damage.

Grey Water
The second type of water that can cause damage is known as grey water. Also classified as category 2 water damage, the water in these cases is contaminated to some extent and may come from unsanitary sources like the discharge from appliances containing pollutants or additives.

Examples would be water expelled from laundry machines, dishwashers, and toilet bowls. These sources of water may have some kind of chemicals that can pose health threats. Grey water can quickly contaminate the property if not immediately treated. If it is allowed to stand untreated for longer than 48 hours, it advances to the most dangerous category of water, which is seriously hazardous for health.

Black Water
This third type of water is highly unsanitary and is known as category 3 water damage. Containing harmful pathogens, black water originates from sewage sources. Along with containing human feces and urine, sewage water also has harmful chemicals and other waste.
Black water also holds serious potential to impair indoor environments with the imminence of causing severe discomfort and sickness.

The Classes of Water Damage

While the different categories of water damage will each entail its own hazards, timely intervention is a deciding factor. This is because standing water yields ideal conditions for mold and mildew growth. Plus, the longer the water stands, the worse the damage becomes.
Based on this, the destruction caused by standing water can be categorized into the following classes of water damage:

Classes of water damageClass 1
This type of destruction is the easiest type of damage to deal with. In this scenario, there is a slow evaporation rate where water damage affects only part of a room. In most cases, there is no or little wet carpet involved and the moisture only affects materials with a low permanence rate like concrete or plywood.

Class 2
Here there is a fast evaporation rate with damage affecting an entire room. Class 2 water damage involves affecting carpeting and cushioning with the wetness having wicked up walls at least 12 inches. This class of water damage may also include moisture retention in structural materials.

Class 3
This type of water damage has the fastest evaporation rate where surfaces such as walls, ceilings, carpets, insulation, and sub floors have all been saturated. Plus, the moisture may also have penetrated from overhead.

Class 4
This type of destruction is identified as specialty drying situation. The destruction caused is brought on by enough moisture and time to let it penetrate materials with very low permanence like brick, stone or hardwood. This type of water damage restoration demands longer drying duration and specialized drying techniques.
