What Category & Class Is Your Water Loss?
The category and class of your water loss refers to the level of contamination in the water, considering its originated source. ALL water damages require restoration, but some cases are a little less severe.

3 Basic Categories of Water:
Category 1 – Originates from a sanitary source. It may not always remain clean after it comes into contact with other surfaces or materials.
Example: Water supply lines, toilet tank, or faucet.
Category 2 – Significant contamination and has the potential to cause discomfort or sickness if contacted or consumed by humans.
Example: Washing machine overflow, toilet overflow, or a dishwasher overflow. These situations can quickly escalate into a Category 3 if not properly taken care of.
Category 3 – Grossly unsanitary contaminated water. This contains human and/or animal waste, along with other contaminants that could cause severe illness or even death if ingested.
Example: Sewer backup, flooding from rivers or streams, standing water that has begun to support microbial growth.
4 Basic Class of Water:
Class 1 – It affects only part of a room or area, or larger areas containing materials that have absorbed minimal moisture.
Class 2 – The entire room or area is affected. Water has gone up less than 24 inches. There is moisture reading in structural materials like plywood, particle board, structural wood and concrete.
Class 3 – Water may have come from overhead. The ceilings, walls, carpet, insulation and subfloor are saturated in the entire area.
Class 4 – Wet materials with very low permeance like hardwood, plaster and concrete have deep pockets on saturation. They may need to be treated with low levels of humidity and often take longer drying times and more specialized methods.
