We cannot say enough good things about this company. Edgar Li and his crew are courteous, prompt, and thorough. We had a lot of questions about the product and process, and he sat down with us so he could understand our needs and answer all our questions. The installation was smooth and quick and the crew left our house tidy and neat. Needless to say, the doors look wonderful. We had a great experience and highly recommend his work.
