What Are the Three Categories and Four Classes of Water Damage?

Understanding the type and severity of water damage is essential for a safe and effective cleanup process. At Restoration 1 of Chester County, we use industry-standard guidelines to classify water damage and determine the right restoration approach for homes and businesses across Chester and Delaware County.

The Three Categories of Water Damage

1. Category 1 – Clean Water: This water comes from a sanitary source such as a broken water supply line. It poses minimal risk if addressed quickly.
2. Category 2 – Gray Water: This slightly contaminated water might come from appliances like dishwashers or washing machines. It contains microbes and can cause illness if ingested.
3. Category 3 – Black Water: This is the most dangerous type, often containing sewage or floodwater. It can cause severe illness and requires professional handling and thorough disinfection.

The Four Classes of Water Damage

1. Class 1 – Minimal Impact: Only part of a room is affected with little moisture absorption into materials. Easiest to remediate.
2. Class 2 – Moderate Damage: A larger area is affected, including walls and flooring. More extensive drying is needed.
3. Class 3 – Extensive Saturation: Typically the result of overhead water intrusion. Ceilings, walls, floors, and insulation are all soaked.
4. Class 4 – Deeply Absorbed Water: Involves materials like concrete, hardwood, and plaster. These require specialized drying techniques.

Why This Matters

Knowing the category and class helps property restoration professionals create a safe and efficient plan to clean, dry, and restore your property. This also assists in insurance claims and minimizes health risks.
