FAQ

Questions we hear first

Yes. Confidentiality is the foundation of our work. Your identity, your situation, and the results of the investigation are never shared with anyone without your written authorization - and every consultation is private, whether or not you hire us.

Yes. We regularly work with insurers, adjusters, and attorneys. Our reports and documentation are prepared to professional standards and can support insurance claims, internal decisions, and court proceedings.

Yes - mówimy po polsku, мы говорим по-русски. Your whole case can run in Russian or in Polish, from the first phone call to the final report. Many of our clients come from the Russian-speaking and Polish communities in Chicago and across Illinois.

Every case is different, so we quote after a free consultation. You receive a clear scope, timeline, and cost before we begin - hourly or flat-fee, with no hidden charges.

For urgent matters - a stolen trailer, an active cyber incident, an immediate safety concern - we can typically begin work the same day. Call the emergency line and we will take it from there.
