We decided to use Trinity to build a large room on top of our garage. The job was a massive undertaking and we were nervous from the start, but as time went on we felt more comfortable as the project began to unfold in a smooth and safe manner. They brought in a licensed structural engineer and architect. At that point we knew we could trust them and the price stayed the same, no surprises. We now have plenty of room and everything looks beautiful. I would recommend them to anyone as a sure safe bet.
