I am an owner for a mixed use commercial building in toronto. There were some issues we noticed with our beams and joists in the basement. Yu was very thorough from the beginning and explained the process to us. He came to the site and gave us practical and efficient solutions to the problem. Report was provided in a timely way and the job was conducted very professionally. Being a builder and investor of real estate you seldom come across professionals who provide creative, efficient and yet proffessional solutions. I would definitely use their service again and recommend to any builders and proffesional in construction.
