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.”

I had all my 18 windows replaced over the last summer. I evaluated two contractors and both gave excellent sales presentations and the prices were competitive. I decided to use Crystal Exteriors because I felt the owner of Crystal Exteriors, Edgar Li, was very professional and willing to work with me, in terms of pricing and other issues. The work was done in a professional manner. After the windows were replaced, Edgar himself stopped by few times to make sure that the windows were satisfactory.”
