IICRC Water Damage Matrix
Determine IICRC Category (1/2/3) and Class (1/2/3/4) for a water loss in under 60 seconds using contamination source, material porosity, and saturation extent. Outputs the dehu pints-per-day requirement and the S500 paragraph reference for documentation.
Open tool → PsychrometricsDehumidifier Sizing Calculator
AHAM-rated dehu capacity converted to derated real-world pull rate, with grain-depression math against your job site's ambient psychrometric readings. Spits out exact LGR or refrigerant unit counts for the loss class and cubic footage you key in.
Open tool → Algorithmic DispatchFleet Efficiency Calculator
Compare your current dispatch latency, deadhead miles, and revenue-per-truck against industry benchmarks. Sized for restoration operators running 2 to 20 trucks, with a per-truck contribution-margin view that surfaces the most-leveraged operational fix.
