Water Damage Classification

Titan Restoration of AZ realizes that not everyone eats, drinks and breathes water restoration. So, we understand that you may not fully understand the topic of water loss classification or its importance. Titan Restoration of AZ thoroughly understands water classification and is prepared to handle any class of loss that you might have. Here’s a primer on what you need to know about water damage classification:


Class 1Slow Evaporation Rate: Water losses that affect only part of a room or area, or losses with lower permeance/porosity materials (e.g., plywood, particle board, structural wood, VCT, concrete). Little or no wet carpet or padding is present. Minimum moisture is absorbed by materials, releasing moisture slowly.

Class 2 – Fast Evaporation Rate: Water losses that affect an entire room or carpet and cushion. Water has wicked up walls 12″ – 24”. There is moisture remaining in structural materials (e.g., plywood, particleboard, structural wood, concrete).

Class 3 – Fastest Evaporation Rate: Water may have come from overhead. Ceilings, walls, insulation, carpet, cushion and sub-floor in the entire area are saturated.

Class 4Specialty Drying Situations: These consist of wet materials with very low permeance/porosity (hardwood, plaster, brick, concrete, stone). Typically, there are deep pockets of saturation, which requires very low specific humidity.
