Hung Tran

August 4, 2022

David Graham was our inspector over here in Minneapolis. He was prompt and great in his communication. He provided some great insight into my sinking front porch and wonky front steps. He did measurements, took photos, and gave me a lot of options and ideas. I learned a lot from David and would recommend him to anyone.
