This year, Mason helped us convert our carport into a garage and also completed a basement renovation. He is incredibly responsible and thoughtful, and he tailored the project to fit within our budget. Throughout the entire process, he closely followed every step and even helped us solve other household issues that weren’t part of the original project. Mason’s crew members were also very polite and hardworking. As Mason always says, he never cuts corners—and the quality of the finished work truly reflects that.
I would definitely work with him again for any future renovations and will certainly recommend him to others. Thank you, Mason, for...This year, Mason helped us convert our carport into a garage and also completed a basement renovation.

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 Contracting.

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.

Everything about this company was better than wonderful. Our project included carpentry, plumbing, wallpaper removal, painting and a bathroom remodel. Meticulous work and attention to detail. We are so happy we hired Mason and enjoyed the time he and Giovanni spent in our home. We are proud to show off all the improvements. Thank you to Mason for being so kind and considerate of our needs. He runs a tight ship and is onsite to check the progress and quality of the work every other day or so. He is very proud of his business and really care about his clients. We couldn't be happier.
