Institute of Inspection Cleaning and Restoration Certification standards governing restoration best practices.
The complete technical guide to structural drying — psychrometric principles, LGR vs. desiccant dehumidifier selection, IICRC S500 air mover placement, dehumidifier sizing calculations, and the daily monitoring protocol that produces defensible drying logs.
The definitive professional guide to water damage restoration — IICRC S500 classification, structural drying science, psychrometrics, moisture mapping, insurance documentation, and the 72-hour timeline that defines every loss outcome.
The IICRC S500 defines 3 water categories and 4 drying classes that govern every decision on a water loss — from PPE selection to adjuster documentation. Misclassification in either dimension is a liability exposure and a direct revenue leak.
