National Inspection Service of Indiana, Inc. is a family owned and operated business that began performing residential and commercial inspections over twenty-four years. The business started in Terre Haute, Indiana in 1992 and expanded to Evansville, Indiana in 1994. We have been providing quality, unbiased inspections for both buyers and sellers throughout central and southern Indiana.
National Inspection Service of Indiana, Inc. provides you peace of mind when making such a large investment of buying a home. We provide a one-stop full scale inspection service, which ranges from single item inspections to entire home inspections. We are also licensed to do wood destroying insect inspections, radon measurement tests and mold sampling.
U.S. homeowners spend billions of dollars each year for control methods and repairs for damage caused by termites. These wood-destroying insects can live in the soil underground and inside wooden structures. Termites are often called "silent destroyers, " since they can thrive inside your home without noticeable signs of damage.
Radon is a naturally occurring radioactive gas released in rock, soil, and water from the natural decay of uranium. While levels in outdoor air pose a relatively low threat to human health, radon can accumulate to dangerous levels inside buildings. You can't see, smell, or taste it, but an elevated radon level in your home may be affecting the health of your family.

NISI have experienced home inspectors. Their inspections are thorough and professional. They explain to the buyer not only defects with the home but also all the positive aspects along with information on maintaining a home.
As a real estate agent, I appreciate the good communication with my clients .

Bob did my inspection for the home and termites for a home I was buying. The report was very detailed and showed very important issues. We appreciate his hard work and the job he did. The lady in the office was very helpful and polite in regards to setting the inspection up as well. I highly recommend using this company. Thanks again!

I highly recommend National Inspection Service. I have used them for 25 years. Rob, Cory and Bob all do an excellent job. And of course Kelly holds down the fort and also does an excellent job. I trust them with my personal home and my childrens homes and most of all my clients homes. They go above board every time. They are very thorough and have a final report to myself and my clients in less than 24 hours. Most of the time we receive the report the same day.

This company is top of the line! They saved me thousands of dollars and many headaches on a house I thought I loved. They were so detailed, leaving no stone unturned. I used them on the next house I loved and the quality was the same. I highly recommend this company!

Rob was on time, a very friendly guy and very knowledgeable, as well as thorough. During the inspection there was a minor mishap, nothing that was a major deal, but was going to require an H-VAC guy to come out and fix the issue that had occurred, and would be handled on his end as his responsibility. To my knowledge he HAS and IS upheld/upholding his end of it and there will be someone there this week. So far, so good. My only reason for giving 4 stars rather than 5 is that this incident and the solution were not listed anywhere in our report and we were not the ones that received information

They have done 2 inspections for us in the last 6 years and we were very pleased with all the helpful information about the home. Rob was very professional and knowledgeable and the report was easy to understand and included photos of items that needed to be addressed. Have recommended them to friends and family and will use the next time we move.
