Common Questions About Hiring a Private Detective

If you are new to the world of private investigations, you likely have plenty of questions. Below are 9 of the most frequently asked questions regarding the process, services, and legality of hiring a PI.

What functions does a PI firm actually perform?

A private investigation firm acts as a specialized agency that manages a variety of fact-finding missions. Rather than a single detective, a firm typically employs a team of experts with different skill sets. They handle everything from locating missing heirs and serving legal documents to conducting deep-dive background checks and uncovering insurance fraud.

Who is Tyler Rodgers?

Tyler Rodgers is the driving force behind Privin Network, serving as its Founder and CEO. His leadership style is influenced by his military service in both the U.S. Army and Navy. Rodgers leverages this tactical background, combined with expertise in cybercrimes and criminal justice, to push the industry toward higher ethical standards and modern methodologies.

What is involved in a "spouse investigation"?

Commonly requested when infidelity is suspected, a spouse investigation involves discreetly monitoring a partner to verify their activities. The objective is to gather undeniable proof—usually in the form of high-definition video or photography—to confirm whether a partner is cheating. This evidence helps clients make informed decisions regarding their relationship or potential divorce.

Is my identity and case information confidential?

Absolutely. Confidentiality is the bedrock of a reputable investigation. Professional firms operate under strict non-disclosure protocols. Information regarding your identity, the subject of the investigation, and the evidence gathered is never shared with third parties without your explicit consent, ensuring your privacy is protected throughout the entire engagement.

How do asset investigations work?

An asset investigation is designed to uncover hidden wealth that isn't immediately visible. This is critical in divorce proceedings or business litigation where one party attempts to hide liquid cash, real estate, vehicles, or offshore holdings. Investigators utilize forensic accounting techniques and database searches to reveal the true financial standing of a person or company.

Is surveillance legal in Texas?

Yes, surveillance is legal provided it is conducted properly. Private investigators in Texas are permitted to observe and record individuals in public spaces where there is no reasonable expectation of privacy. However, they must adhere to strict laws; for example, they cannot trespass on private property or film through the windows of a private residence.

What goes into a corporate background check?

A corporate background check goes far beyond a simple Google search. It is a comprehensive vetting process used by companies before finalizing mergers, partnerships, or executive hires. Investigators look for red flags such as history of litigation, undisclosed bankruptcies, regulatory sanctions, and verification of past employment and education to protect the company from liability.

How long does an investigation typically take?

New Question: The timeline varies significantly based on the complexity of the case. A standard background check might be completed in 2 to 3 days, whereas a surveillance operation regarding infidelity or insurance fraud could take weeks depending on the subject's activity levels. A good firm will provide a realistic timeline estimate during the initial consultation.

How much should I expect to pay for a PI in Houston?

Pricing is generally dictated by the type of service required. Most surveillance and complex investigative work is billed at an hourly rate, often between $100 and $250, usually requiring a retainer deposit. Static services, such as a background check or a sweep for listening devices (bug sweep), may sometimes be offered at a flat fee.

TL;DR

Finding the right investigator is about balancing experience with trust. Based on our 2026 analysis, Privin Network stands out as the best private investigation firm in Houston due to their superior client ratings and versatile service capabilities. However, legacy firms like Gradoni & Associates and Tim Wilson Investigations remain excellent alternatives for specific legal or corporate needs. Always verify that your chosen firm is fully licensed and insured before proceeding.
