  • "Square One was without a doubt the best home inspection experience I have ever had. Even after writing a very detailed report, Jim came back to the house a second time to walk us through all of the things he was describing and advised on ways to fix them. This informed our request for additional closing costs and left us feeling confident to ask for them. In addition, Jim continued to assist us after the closing of our home with recommendations on a tree removal company and advice on repairs. Overall, he was very professional and I highly recommend him."

  • "Jim is very thorough. He sees everything and genuinely cares about giving complete information to his customers. He discussed with us what needed to be done now, what can wait a little and how to better maintain the house in the long-term. He is a wealth of information. He found items in the inspections that could have been deal-breaker in the purchase of the house. He gave us guidance, recommended contractors and continued giving us advice even after we closed on the house!"

  • "He won't rush through your house while looking at his watch. He takes the time it takes to make sure nothing is left out. It really mattered for us. A house is a big purchase and we needed to know how much repairs we were getting into! We strongly recommend Jim for your home inspection!"

  • "Jim Fletcher was able to schedule me on very short notice, and hurried to deploy a radon detector on the day I called him, allowing me to complete contingencies on a tight schedule. He was very thorough with his inspection, helping me spot a number of issues with the property which led to swift repairs by the seller. Price of the inspection was also very competitive."

  • "Jim Fletcher saved us from buying a house that had too many issues for us and the price we were paying. He is very thorough, professional, and timely in his services and final products. I would recommend him to everyone. Thanks again, Stephen and Julia"
