"Working with Sino-America General Contracting was excellent from start to finish. Our project was a complete redo of the basement - we had demo'd floors, walls, and ceiling ourselves, and hired Mason and his team to help install a custom bathroom under the stairs complete with custom shower pan, under floor heating, and tiled walls. We also had them build a small mechanical room, install insulation, redo flooring, redo drywalls, build a drywall frame around the HVAC, install new vents and ducts, and install recessed lighting. They also built a bannister for the stairs leading to the basement and installed a matching railing and bannister for the upstairs. Finally the installed new doors for the upstairs and downstairs, and moved the downstairs door to the right a few inches in order to accommodate our design. This necessitated external brickwork and they were able to match the 70 year old brick extremely well. From the initial meeting Mason was responsive and professional as we went back and forth on the design of the bathroom. The designer (whose name I sadly can't remember) did a fantastic job with clever use of space and a keen understanding of how the design will translate into real life. Experienced in AutoCAD - they provided clear and very accurate 2D renderings and beautiful 3D renderings of the finished design, including 3D renderings of the style of sinks, toilet, lights, and mirrors we wanted. The contract was well presented and explained with the scope of the project clearly identified. At no point was anything unclear. He worked with a punch list with holdback until the punch list completed. Communication of contractor's needs and schedules were well coordinated with mine so there were no surprise missed days. Worked weekends to help expedite project completion. Any issues or concerns that we had during construction were explained or addressed right away. There was an accidental error during installation of the under floor heating and Mason and his team addressed it which required removing tile, reinstalling the heating system, testing, and replacing tile. They built a good relationship of trust with excellent communication throughout The quality of the work is excellent and stands up to close scrutiny. Smooth, crisp, and even drywall and corners, including on strange angles and niches. Beautiful, uniform color application Beautiful tiling and corners. The attention to detail was also very good. As an example we turned the remaining space under the stairs into a kitty-litter area including custom trapezoidal door and externally vented bathroom fan. Despite it being in a low-traffic area, all the work in that miniature room was of the same quality - crisp corners, well-joined shoe-moulding, and nicely painted edges. I recommend Sino-American Construction without hesitation."
