Thunder Valley Asset Group is a fully licensed, bonded, and insured private investigative agency serving Western Washington. Our team integrates a unique military background as well as construction contracting. This hybrid expertise allows us to navigate complex operations with the integrity, technical structure, and rigid discipline required to deliver court-ready results. Our motto, Tenebras in Lucem Exturbare, means we seek to drive the darkness into the light. Investigating is not just our career, it's a passion.
Our Commitment to Protection
In Washington, the state requires a minimum bond for licensure. We don't believe "minimums" are enough for our clients. We carry comprehensive Professional Liability (E&O) and General Liability insurance that goes well beyond state requirements. We do this not only to protect our agency but to provide an extra layer of security and peace of mind for the clients who trust us with their most sensitive matters.
At Thunder Valley Asset Group, we handle sensitive data with professional-grade security. We do not transmit confidential reports or investigative findings via standard, unencrypted email. All final reports and sensitive documents are delivered through a HIPAA and GLBA-compliant encrypted portal. This ensures that your private information remains protected from unauthorized access and is only accessible to you through a secure, verified connection.
Integrity Over Promises
In the investigative industry, nothing is certain. We have seen others in this field make lofty promises or "guaranteed results" just to secure a contract. We believe those practices give our profession a bad name.
At Thunder Valley, we don't promise outcomes—we promise effort and expertise. Whether your case is a small-scale locate or a high-stakes corporate investigation, you will receive our absolute best efforts, utilized through legal, ethical, and skilled means. We provide the highest quality discretion and professionalism in our investigative services, court-admissible reporting, and transparent billing.

How much does it cost to hire a Private Investigator?
Every case is different, but we believe in 100% upfront transparency so you can budget accurately.
Background Checks & Skip Tracing: Simple locates and comprehensive asset or background profiles are typically handled at a flat rate, starting between $105 and $500 depending on the depth and intensity of the search.
Field Surveillance: Active field operations (like child custody, domestic cases or insurance fraud) are billed at an hourly rate, generally ranging from $105 to $125 per hour, plus mileage.
We discuss all costs upfront during your free consultation and work within a capped retainer, meaning we will never exceed your agreed budget without your explicit permission. No hidden fees, no surprises.
