"Tom was in a word: Phenomenal. I scheduled an Inspection and Radon Test on HomeAdvisor. Tom reached out within minutes of my scheduling the appointment. He was extremely thorough yet timely and gave simple suggestions. The last thing he sought to do was to nickel and dime us- we truly appreciated that. He was very personable and kind. His prices we the best in the area (we shopped around) and the quality of his work speaks for itself. We've favorited him and will be giving him a ring for our next home."
