Author and curator · RestorationCalcs
Francesco Zinghinì is the author and curator of RestorationCalcs. This is a truthful role: I am not an IICRC-certified restoration technician, industrial hygienist, certified mold assessor, NRPP/NRSB radon professional, licensed asbestos/lead abatement contractor, physician, insurance adjuster or attorney, and I do not claim any such trade, health, insurance or legal credential.
My relevant, verifiable competence is building deterministic online calculators (open-source Python projects) and engineering training — rigor on the arithmetic and sizing math. Every formula on this site shows its basis, every convention is cited under Sources, and every calculator is numerically self-checked against known values (see Methodology).
Everything here follows one rule: the tools must stay correct with no ongoing maintenance. That is why every cost tool works only on the quantities you measure and the prices you enter from your own quotes and bills — the site keeps no restoration price list, no regional cost database and no live rates that would silently go stale. The only baked-in numbers are stable identities (27 cu ft per cu yd, 0.623 gal per sq ft per inch, the ACH ↔ CFM identity), EPA thresholds (mold ~10 sq ft, radon 4 pCi/L) and clearly labeled IICRC/AHAM sizing and cost-band typicals you can adjust to your own project.
Restoration is a real spend and, with sewage, biohazard, mold, radon, asbestos and lead, a real safety matter. So every cost tool is framed as a planning estimate, not a bid; the Category 2/3 water, sewage and biohazard tools carry a plain health-hazard reminder to hire certified pros; the mold tools note the EPA 10-sq-ft threshold and that this is not medical advice; the radon tools note the EPA 4 pCi/L action level; the asbestos and lead tools note they are regulated hazardous materials; and the insurance tool is illustrative only. The aim is a neutral, free, no-signup reference you can use to sanity-check a contractor’s numbers — nothing that pretends to replace a professional.
