About  Us

Long story short

We are Dion and Brittany Coomber, and we are the founders of Cornerstone Property Inspection. One of the most rewarding things about owning your own business is that you are in charge of the way you do things. We are committed to doing everything we can to serve you with integrity.

No, O people, the LORD has told you what is good, and this is what he requires of you: to do what is right, to love mercy, and to walk humbly with your God. – Micah 6:8 

We started our business in 2016 with a focus on single family residential inspections with one inspector. We are now a team of inspectors with expanded expertise in the areas of new construction, frame/MEP, shear wall and foundation inspections. We hold IRC certification along with the TREC inspection license. Our team handles both residential and commercial inspections on a day to day basis.  

We would love to have the opportunity to learn more about how we can partner with you and your family or you and your clients.

What our customers say

Our business is only as good as your experience working with us.

“Buying our first home has been exciting, but extremely nerve-racking. It’s important to rely on people you trust through the process. So thankful for Cornerstone Property Inspection for going the extra step to teach, guide and ensure our understanding of the inspection findings in our new home. Also, Dion has responded quickly to my questions and was able to get the inspection done on the weekend at the last minute, which is a huge relief considering the quick process! No wonder he came to us highly recommended!”

Caroline & Davis Goodwin | First Time Homebuyers

“Dion with Cornerstone Property Inspection did 2 home inspections for us and we could not have been happier with both experiences! He was recommended by our realtor the first time and we made sure to request him for the second one. He is extremely knowledgeable, thorough, and exceeded our expectations! He was a pleasure to work with and we are very thankful for his expertise! We would absolutely recommend him to anyone needing a home inspection.”

“Dion is a great inspector and always does an amazing job for our clients! Our team really enjoys working with Cornerstone Property Inspection!”

Andrea Lundsgaarde | Realtor

“Dion was a pleasure to work with!! He came and inspected our new build and found several things that the builder did improperly and some that were just incomplete. We feel so much better living in a home that wasn’t just builder inspected but privately also! We will definitely do business with Cornerstone again. Very happy and prompt!”

Dion was incredibly personable and thorough. He was incredibly detail-oriented and was a true advocate for us (the buyers). He has helped us make a truly informed decision about one of the most important transactions we could make-- a new home for our family. I am confident in our decision thanks to him and know that the house will be a safe one after sellers make requested repairs thanks to his report.

Dion was incredibly flexible and easy to communicate with. He caught a lot of issues for us to be wary of and provided the final document in a timely manner as well. He was incredibly professional and kind! Would love to refer him to our friends.

Dion is incredible at what he does! I was recommended him by my realtor and I am so glad. He was such a friendly face to meet with, extremely knowledgeable, professional and helpful to me as a first-time home buyer. While I hope I don’t have to see Dion again for a while, I would recommend him to everyone!

Cornerstone Property Inspection went above and beyond to provide an extensive report on our new build. This service pays for itself by uncovering multiple issues that we can have the builders remediate. In many cases they were issues I would not have identified on my own. You can tell by the attention to detail, and detailed explanations of his findings that Dion is passionate about his work. Would highly recommend.

“Looking for an inspection company who will over deliver on everything? How about one who will find everything possible for a home you’re purchasing? Or one who will shoot straight with you about your existing home regarding items that need to be addressed? Want an inspection company who cares more about you as a homeowner than just getting the business done? Look no further than Cornerstone Property Inspection!”

“Dion was great! He was extremely detail oriented. He told us he had felt a little bit of a slant in the house and he said he had a gut feeling there was something wrong with the foundation. He recommended we have a company come out and measure- turned out we needed 8 piers put into the foundation! Dion was super nice and always texted us back promptly. When we buy our next house, we will definitely be calling Cornerstone.”

Lauren & Luke Hale | Happy Customers

“Having a home inspection done on our new build was a must. We were extremely pleased with the quality of work, excellent customer service, and professionalism that we received from Cornerstone. Dion took the time to walk us through each part of the inspection and found building mistakes that we never would have known to look for on our own. We now have piece of mind that our new home is up to standards and nothing was missed in the building process. We recommend Cornerstone to all of our friends and family.”

Caitlyn & Dustin Kincaid | New Construction Homebuyers

“Highly recommend these guys. Dion was extremely professional, and walked us through each and every aspect of the inspection with attention to detail and didn’t hesitate to answer any questions. Very personable. It didn’t feel like a transaction, it was more like a friend helping us out. Thanks Dion.”
