I found this company based on their reviews in May 2025. One thing that stood out was that all the…read morereviews were positive and five stars. Even though their price was a bit higher than the company my agent recommended, I decided to go with them -- after all, buying a house only happens a few times in a lifetime, and you want true professionals for something that important. Looking back, it was absolutely the best decision. Jay did my inspection and was extremely thorough and professional. A few months later, I had a question and reached out to Ian -- that's when I truly understood why everyone gives them five stars. He provided excellent customer service, stood by their work, and was very responsive and helpful. Overall, this is a great company with outstanding customer service. Highly recommended!
