Our Client Testimonials

Here’s what our inspection clients have to say about their experience with NPI.

Seth F.
I recently used National Property Inspections and was thoroughly impressed with the level of service provided. Mark and his crew were highly professional, diligent, and articulate throughout the entire process. Their attention to detail gave me full confidence in the property’s condition and in my next steps. I highly recommend NPI.
Neal K.
Awesome job by the inspector. They showed us many areas to watch in the coming years, were very thoughtful, and didn't rush. Proud to serve veterans. Their experience was evident and we knew they were there to help and not to just complete paperwork. They know their stuff. Highly recommended.
Tiffany G.
This was a great experience. Mark made me very comfortable and proud of the home I bought. I felt he knew what he was looking for and helped make me have knowledge about it also. He did find some minor things and took time to discuss options on how to address them. Just a wonderful person working for a great company. Can't beat that!
Audrae W.
We picked NPI because Mark had inspected two other homes for family members and he did a thorough job. We knew we could trust his report to know if this was the home for us - and it is! Thank you Mark and Tracy for taking pride in the work you do. We are looking forward to making new memories in our new home.
Gerold S.
Mark and the NPI team are awesome! Mark is very thorough and very trustworthy. Seventeen years ago I had him look through my current house and all the areas he talked about then were very accurate. If we end up moving again at some point, we will continue to use him and will recommend his services to anyone we come across. Thank you, Mark!
Alexandra M.
Mark was incredibly helpful! His inspection was thorough but he also took the time to explain everything to us, give advice, and talk us through his process. We have incredible peace of mind after that inspection.
Mark R.
Mark and Tracy were great to work with. Their communication was amazing and their post-inspection was great. I was able to meet with Mark so that he could address some of his concerns and things he liked about the building. I am extremely grateful and would highly recommend them to anyone looking to purchase a new home or office building.
Bob & Trish H.
We initiated this inspection to help identify repairs/updates necessary to prepare our house for a future sale. Mark did an excellent job of identifying those needs and their priority while also answering all of our questions. The report was very thorough and exactly what we wanted. Thank you, Mark!
Cassie S.
We joined the inspection with Mark and found it incredibly informative. He even took the time to teach my sons about how to turn off the power, water, and gas in emergencies. He absolutely went above and beyond what we expected. I would not work with anyone else after this experience.
Brianna W.
We had an incredible experience with Mark at NPI. Mark did a great job of educating us on elements of our home, explaining all of the utilities and safety features. He was also very personable throughout the whole process. We would 100% recommend them to our family and friends! Thanks for such a great experience!!
