Biohazard Claims Group is a nationwide estimate review and valuation service marketed to insurance companies for property loss claims resulting from crime and trauma scene type situations where biohazards/bodily fluids contaminated a property and mitigation clean up services where required. Clean up estimates are reviewed prior to payment from insurance carriers to verify that expenses related to a clean up are fair and just. Biohazard Claims Group was started by Marc Onesta, an expert bio-trauma remediation specialist.
