Water, Fire, and Mold Restoration
If your home has recently suffered water damage or a water related disaster, determining the classes of water loss is an important step in beginning water damage restoration. Identifying the classes of water loss enables restoration professionals to formulate a plan based on your home's specific needs.
The Four Classes of Water Loss
Classes of water loss refer to the amount of water and the anticipated rate of evaporation based on the amount and type of wet materials in your home. There are four classes of water loss:
A class one water loss affects only part of a room with low-permeance or low-porosity materials such as particle board, plywood, structural wood, vinyl composition tile, and concrete. Learn more.
Class two water losses affect the whole room and materials such as carpet and cushion. Seepage of water up walls is less than 24 inches, and moisture remains in structural materials. Learn more.
Class three water losses typically come from overhead, saturating insulation, ceilings, walls, carpet, cushion, and subfloor in virtually the entire area. Learn more.
Specialty drying situations involve wet materials with very low permeance or low porosity. Examples include hardwood, plaster, brick, concrete, stone, subfloors and crawlspaces. Learn more.
Categories of Water Damage
In addition to identifying the classes of water loss, it is also important to identify the state of the water effecting the damaged materials. Simply put, how clean or dirty is it? There are three categories of water damage:
Category 1: Sanitary Liquids
These liquids are from sanitary sources such as faucets and toilet tanks, but they can quickly degrade into category two liquids.
Category 2: Grey Water
These liquids come from sources such as dishwashers, washing machines, sink drains, and toilet overflow (urine only), and contain contaminants that may cause illness or discomfort if ingested.
Category 3: Black Water
These grossly unsanitary liquids include sewage backup, feces contaminated toilet overflow, flooding from rivers or streams, and bacteria laden stagnant liquid, and can cause severe illness or death if ingested.
