Restoration Calculators
Field-ready engineering tools aligned to IICRC S500 guidance. Enter your loss parameters and let the math do the arguing. Designed for mobile — every input opens a numeric keypad.

These are field-ready engineering tools built to the IICRC S500 / S520 standards. Follow these four steps on every job.
Add Your Rooms
Click "Add Room" in the Job Setup panel. Enter each affected room's dimensions (length × width × height), which surfaces are wet (floor, walls, ceiling), the material type, and water height if standing water is present. Add every room — the calculators combine them automatically.
Pick the Right Tab
Select the tab that matches the job type: Water Damage for drying equipment sizing, Mold Remediation for containment and ACH, Fire & Smoke for ozone/hydroxyl and air scrubbers, Reconstruction for cost estimation, or General Tools for psychrometrics and power load.
Adjust the Parameters
Each tab pre-fills from your room data. Override any field — water source, class of loss, dehu model, NAM CFM — to match what you have on the truck or what the job actually requires. The results update instantly.
Email the Results
Hit "Email Results" at the bottom of any calculator to send a formatted summary to yourself, the adjuster, or the property owner. Use it as a quick scope document or leave-behind for the insured.
Why This Matters on Every Job
Numbers backed by IICRC S500 / S520 are harder for adjusters to dispute. Show your math.
Calculate equipment needs on the way to the job — not after you arrive.
The #1 cause of failed drying goals is too few air movers or wrong dehu class. These tools catch that upfront.
The Fire & Smoke tab's inventory separates total-loss, salvageable, and cleanable items for the adjuster — in the field, not back at the office.
Newer techs can use the reference guide and calculator together to learn the IICRC standard as they work.

IICRC S500 Disclaimer
These calculators are simplified engineering aids derived from the ANSI/IICRC S500 Standard for Professional Water Damage Restoration and related air-quality guidance. They do not replace on-site assessment by a certified restoration professional. Actual equipment needs depend on psychrometric conditions, building materials, contamination category, containment, and airflow obstructions. Always defer to manufacturer specifications and the current IICRC standards. Reference the IICRC standards at iicrc.org.
