I met the Sentrex family almost ten years ago in a muddy stockyard filled with 100KM of conduit that needed to be installed. Sentrex felt like an organic extension of our company from Day One, not afraid to tackle the hard questions with experienced-backed solutions. I have never needed another principal contractor since. Sentrex has a level of professionalism and industry understanding that only comes with experience, practice and the knowledge of what makes the team and project work.”

“I wanted to thank you again for making our build project such a great success. This was one of the craziest years in history and there was a lot riding on it. Your team made it a real pleasure to work with and handled each challenge extremely well, from the tight schedule, to working in an environment with restrictions from our landlord and our demands on how to handle the construction schedule. The most impressive thing to me was when your team came across a challenge, they always came to me with a viable solution. From the start of the process to the finish, it went very smoothly. I was impressed with the professionalism of you and your team. Having worked with construction crews before, I think you have some of the best people, hands down. I look forward to working with you and your team again in the future.”
