“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.”

“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!”
