"Robert was very pleasant to work with. He answered my request for a quote within minutes of my request. His price was lower than other quotes. He stayed in touch with me and showed up on time. Robert took his time and did a through inspection of my home. He explained issues he found and suggestion on how to fix some. His written explanation was documented with many pictures. I would highly recommend Robert for inspections of your home. Thank you!"

"My experience with Patrick can be summarized as thorough, detailed, and honest from start to finish. From my first phone call with him, it was clear that Patrick truly had my best interest at heart. He explained the entire inspection process, including how long we would be at the home and what he would and would not review during the inspection. Patrick even took the time to pull up the property online while we were on the phone to advise me on his concerns and some additional services to consider before buying the home; no other inspector we called put forth this effort. Upon arriving at the home, Patrick quickly set up shop. On the kitchen counter, he immediately laid out his tools, radon detector, and the snacks he was kind enough to bring for us. From there, we systematically began inspecting each room of the home with Patrick narrating his thoughts aloud. He explained his concerns and safety issues, and he provided many recommendations on fixing and maintaining the home in the future. As a first time homebuyer, Patrick was patient with answering all the questions I had in a clear, understandable manner that left me feeling confident in my ability to care for the home in the future. After the 6-hour inspection, Patrick quickly sent me a 16-page report, all photos he took during our visit, and all city permits on file for the home for me to review. I highly recommend Patrick if you need a building inspector."
