Mason has done many jobs for us over the past decade, all of which we were extremely happy with, but the project he completed for us in 2025 was just magnificent. He took a very small rambler and turned it into a modern masterpiece. He doubled the house in size, added a new roof, and completely renovated every inch from floor to ceiling. Our expectations were more than exceeded. We were thrilled! If you are considering a major renovation, I would look no further than Sino-American General Contra

Sino-American general contracting company will be one I will go back to for future contracting work on my house. I also feel confident to recommend my friends and neighbors and relatives of this company. The work on my 2 bathrooms and my laundry room was done beyond my expectation. Service was excellent and labor was reliable and respectful.

From beginning to end, Mason and his crews were skillful and professional and Mason is a GREAT communicator and project manager. Our renovation in Georgetown was beautifully executed with incredible attention to details. And Mason was wonderful helping us through every step, always accessible to meet and to respond to emails and text messages. He helped us to maximize the space we had, and to do so in an aesthetically pleasing way. He helped us in working with complicated issues due to the age

I wanted to share a recommendation for Mason and his team at Sino-American General Contracting. Mason has successfully completed several significant projects for us, including a comprehensive basement renovation, construction of a four-season addition, and building of a new garage. Across all of these projects, Mason has consistently demonstrated exceptional professionalism, craftsmanship, and dedication to client satisfaction. In our experience, there are a few things that set Mason and Sino-A

Mason and his team did a complete remodel of our Washington DC row house, and the experience felt like watching a blueprint breathe itself into life. They handled everything end-to-end design, permits, construction, even the delicate diplomacy with our neighbors. Mason truly listened to what we wanted and translated our vision into something even better, all while staying within budget. The final result is stunning, and we couldn’t be happier. Highly recommend.

I cannot recommend Mason and the team at Sino-American General Contracting enough. We hired them for a complete rebuild of our basement, and the results are absolutely stunning. Beyond the beautiful cosmetic work, what really impressed me was how they handled the technical side of things. Mason navigated the permitting process and ensured we passed every single inspection without a hitch. Their attention to detail is impeccable, and you can tell they take true pride in their work. If you are lo

Mason and team built a porch for us in 2021 and four years later it has held up beautifully. This is a testament to their attention to detail and the quality of their finish work. The first few years it felt like every time I sat out there I noticed another detail that was done very well. They kept us informed of the progress throughout and took care to make sure that the final product would be what we had in mind. The crews were professional, took care on our property, and the left the construc

My wife and I used Sino-American GC for two major renovation projects at our house: (1) remodeling our attic, including the construction of a new interior bathroom; and (2) replacement of an open deck with a screened in porch. Both experiences were great, and the work was outstanding. Mason and his crews were responsive and detail-oriented, and actively worked with us on design choices. He helped us through every step of the process, from project conception through design and construction.
