I live in Dallas Texas and I was looking for a detective in the Chicago area. I got a quick response. I was a little skeptical but Eric sounded very knowledgeable and trust worthy. He did not beat around the bush. He gave me a great rate which was what I needed. He got to work really fast and got me answers. I was really satisfied. He was able to locate the person for me and now I am in the process of serving them. I just call him and he is really reliable. He is there for you because he really cares and not because he gets paid for it but he was sooo understanding. I owe him a lot! He is amazing! I will definitely recommend him to anyone who needs help finding someone and not wanting to spend an arm and a leg!

I was very skeptical of hiring anyone to provide process service since the previous individuals we used could not finish the job after 19 tries. After hiring Lyght Detective Agency we were pleased to see that the job was completed in one day, it was handled efficiently, he very responsive and we definitely will use the Agency again if need arises and highly recommend him. Thank you so much for handling this job for us.

A job well done! I am a norwegian, living in Norway. Me, and my family have been trying to locate the whereabouts of my wife's father, as she has never had any contact with him. After many attempts, we decided to hire a privateinvestigator. I sent email to three different investigators after a quick search on the internet. One office gave me a very diffuse price, one did not answer, and one gave me a quick answer, with a price of total cost. We hired Heritage Investigations, and the detective was very fast working, and the dialogue was incredible good - despite the fact that we ar eon the opposite side of the world. It took Heritage Investigators just about a week to close the case and make the contact, and now we are happily connected with our relatives. We sincerly recommend anyone who needs help from a detective to contact Heritage Investigatons. You'll get a job well done, fast and very correct, and the price they charge is highly acceptable. Best regards Thomas

The company was fast and reasonable in their pricing. Originally, the information I received was not exactly what I had wanted. When I expressed this to the company, I had the necessary information within a day. I would definitely use them again.

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

What does a private investigator do?

First and foremost, good private investigators follow laws. Unlike on TV, they don’t break in windows or hack into hospital computer systems to get you intel. When you hire a private investigator, you’re hiring a professional to gather facts and find information for you. Although they can’t obtain certain information (such as health records), they do have access to information that most civilians do not. Often private investigators are hired to perform surveillance or background checks or investigate cases such as adultery, child custody, missing persons, hidden assets, or debugging, and theft or other crimes.

Private investigators can be hired to interview people and provide that information to the client, perform photo or video surveillance, monitor activity at a location where you suspect criminal activities or questionable behavior, track a person’s movements, find missing people, do deep-dive background checks, and more. Private investigation can be helpful if you’re trying to get a court order but need evidence. Private investigators can also help find birth parents. Nationally, the average price range for private investigation is $70-$210 per hour.

What does a private investigator cost?

Private investigation isn’t just for blockbuster action movies. Hiring a private investigator can help in all kinds of situations ranging from finding a birth parent to improving personal security. Nationally, the average price range for private investigation is $70-$210, although pricing often hovers between $40 and $100 depending on the complexity of the services you need. Where you live in the country will affect your costs for private investigation; larger cities have higher business overhead and a higher cost of living, which in turn means higher service rates. The complexity of your case can also affect cost. A basic background check may have a flat rate, while hiring a private investigator to help with your child custody case may require more legwork and research, and therefore cost more. Some private investigators work on retainer. A retainer is essentially a nonrefundable deposit you pay to the professional — meaning you have retained their services — who then works against that amount. Here are some examples of average private investigation costs:

  • Hourly rate: $60-$70; costs can vary based on current fuel prices.
  • Flat rate: $100 for comprehensive background investigation services.
  • Retainer: $1,500 minimum retainer required by some pros before starting work.
