    This company was recommended to me by a friend, and I am so glad that I took the advice. The owner, Sam, is a perfect gentleman and did a superb job renovating my kitchen and bathroom. He's an experienced plumber and electrician, so never needed to call in subcontractors. The price he quoted was fair, and he never asked for more money because the job was proving "more difficult than expected". My experience with contractors in the past has been spotty, but Sam was honest to a dime, and even added upgrades at his expense because he thought they made the work look better. He runs a tight little team who are perfectionists. He frequently asked me if everything was to my liking. Communication was perfect; I never had to wait for an answer to a question. I highly recommend this company.

    Three months ago, a friend recommended Huaxin to do a full house renovation for me. This is a very responsible company. They are very professional in design, material selection, and meticulous workmanship, especially the background wall, which is very unique. Johnny is very good at communication. He confirmed every process with me and strictly controlled the construction period. It took only more than a month to complete the decoration and delivered it to me ahead of schedule. I am very satisfied and it is worthy of everyone's trust.

    Install or replace gas systems and pipes-
    We had a gas line issue — there was a faint smell in the basement, and we needed someone to take a proper look. A technician named Sean came by quickly, asked a few questions, and got straight to work. He walked through everything step by step, checked all the connections, and found where the problem was. It ended up needing a small repair, and he explained exactly what he was fixing and why. He didn’t waste time, didn’t try to sell us anything extra, and made sure everything was safe before he left. The price was very reasonable for the work he did. Overall, it was a solid experience. We felt taken care of, and we’d definitely call him again if anything else comes up.
