"My inspector, Justin, did a great job with my apartment inspection. He was very thorough and found that the dishwasher wasn?t working, which was really important for me to know. Because of his inspection, I?ve decided I don?t even want the place if they aren?t going to fix it. I?m glad I was able to be there the whole time, and Justin took the time to answer all of my questions clearly. I really appreciate his professionalism and would recommend him to anyone needing an inspection."
