During the in-person consultation (after a few phone discussions) and minutes before the inspection, Tory's professionalism and demeanor gave me the confidence I wanted before going into this inspection, as I left him and his assistant alone to complete the inspection. The inspection was completed promptly, and the detailed results were emailed soon thereafter. Tory followed up to ensure that I had received the report and to ask if I had any additional questions about the report. After reviewing the detailed report, of course, I had questions about the recommendations, the best methods to correct it, and Tory's opinion on estimated costs and timelines for the corrections. True to form, Tory gave an exhaustive explanation for the inspection report and assured me to call again if I needed more assistance. Finally, this experience with working with Tory was everything I needed to move forward with our real estate project. The decision to use Tory, with his experience, demeanor, and professionalism, will result in a follow-up call for any new or existing home improvement projects. It was wise for me, and it would be wise for anyone to choose this company for your inspection needs.
