Before our renovation began, we asked 3 GCs to submit bids. When the bids came in, Sigma stood out immediately. They gave us a clear and detailed Scope of Work specifying what will be done and the materials that are owner supplied. That way, we were able to easily budget our cost accurately. Throughout the 6 weeks of renovations, there were changes we wanted to make to one of the bathrooms, and they were receptive and willing to cooperate. Finally, they delivered in the timeframe that they initially promised. Their quality of work is definitely top notch and there is nothing we could complain about.
