Structural Drying Time Estimator

Estimate how long water damage will take to dry using IICRC S500 standards. Results include equipment recommendations and a monitoring schedule.

Drying Time FAQs

What is IICRC S500 drying standard?: IICRC S500 (Standard for Professional Water Damage Restoration) defines equipment ratios, monitoring intervals, and drying goals for structural materials. It requires 1 air mover per 50 sq ft and 1 dehumidifier per 200 sq ft as baseline.
What happens if drying takes too long?: Materials that remain wet beyond 48–72 hours are at high risk for mold colonization (IICRC S520). Extended drying also increases structural damage as wood swells and warps, drywall deteriorates, and subfloor adhesives fail.
Should I run my home HVAC to help dry faster?: Standard HVAC is not sufficient for structural drying — it lacks the airflow and dehumidification capacity required by IICRC S500. Industrial air movers and dehumidifiers are required for proper structural drying.
