1. Project Information

Project / Customer

Affected Room

Length (feet)

Width (feet)

Ceiling Height (feet)

Affected Floor Area (sq. ft.)

Water Category Category 1 — Initially sanitary Category 2 — Significantly contaminated Category 3 — Grossly contaminated

Approximate Time Since Loss Under 24 hours 24–48 hours 48–72 hours Over 72 hours Unknown

Water category must be established through a site assessment. Time, source, and conditions can change contamination risks.

2. Affected Materials

Drywall

Insulation

Carpet / Pad

Hardwood Flooring

Wood Subfloor

Tile / Underlayment

Cabinetry

Concrete / Masonry

3. Psychrometric Readings

Indoor Temperature (°F)

Indoor Relative Humidity (%)

Outdoor Temperature (°F)

6. Field Documentation Checklist

• Confirm source, water category, and extent of migration.
• Document moisture mapping and affected assemblies.
• Record material-specific moisture readings and dry standards.
• Record ambient temperature, RH, GPP, and equipment readings.
• Identify hidden cavities, layers, and potential vapor barriers.
• Document equipment placement, changes, and daily progress.
• Confirm drying goals through appropriate verification.

Professional-use notice: This is a preliminary planning aid, not an IICRC certification, engineering determination, or substitute for a qualified onsite assessment. Equipment counts, demolition decisions, drying targets, and safety controls must be established from actual conditions and current applicable standards.

YOUR NEXT STEPS AT A GLANCE

1. 1 / SOURCE

   Stop the leak safely

   Arrange source repairs and identify where the water began.

2. 2 / SPREAD

   Map affected materials

   Check adjoining rooms, flooring layers and the space below.

3. 3 / DRY

   Measure the progress

   Extraction starts the process; moisture readings guide drying.

4. 4 / REVIEW

   Keep the records

   Save photos, readings and the agreed restoration scope.

A dry-looking surface does not establish that concealed materials are dry.
