IICRC S500 Standard Workflow
Water Damage Restoration Process Timeline
Click any phase below to learn what happens, what equipment is used, and typical duration. This is the standard IICRC S500 workflow used by certified water damage restoration professionals.
Phase 1: Emergency Response & Inspection
Hour 0-2Licensed restoration professionals arrive on-site, assess safety conditions, identify the water source, and document the scope of damage with photos and moisture readings. The water category and damage class are determined based on IICRC S500 criteria.
Standard activities
- • Safety assessment (electrical hazards, structural concerns)
- • Water source identification and shutoff if needed
- • Pre-existing damage documentation
- • Initial moisture mapping with thermal imaging
- • Water category classification (Cat 1/2/3)
- • Damage class determination (Class 1-4)
Typical equipment
- • Thermal imaging camera
- • Moisture meters (pin and pinless)
- • Documentation tools (camera, moisture maps)

Why this matters
Understanding the standard process helps homeowners ask informed questions, verify their contractor follows IICRC S500 protocols, and set realistic expectations for project timelines. Mitigation (phases 1-6) is governed by IICRC S500; reconstruction is a separate phase typically handled by general contractors.

Why understanding the process matters
Water damage restoration follows a standardized workflow defined by the IICRC S500 Standard for Professional Water Damage Restoration. Knowing the steps helps homeowners verify their contractor follows industry best practices, ask informed questions during the project, and set realistic expectations for timelines and outcomes.
Mitigation vs reconstruction: The IICRC S500 workflow covers phases 1-6 (inspection through drying verification). Reconstruction — rebuilding what was removed during demolition — is typically a separate phase handled by general contractors rather than restoration specialists. Reconstruction costs typically run 1.5-3× the mitigation phase.
Documentation matters: IICRC-aligned contractors document daily psychrometric readings (temperature, relative humidity, moisture content) throughout the drying phase. This documentation is often required by insurance carriers to justify the project scope and duration. Ask your contractor for the drying log when work completes.
