Rated 5 out of 5 by from Fantastic experience I have used California Distribution Center to replace my old, creaky windows in two houses now and have found Doug Lopez's knowledge, professionalism and promptness to be first rate. Additionally, I have recommended his company to many friends and neighbors over the years and will continue to do so as I've not found even the slightest reason to shy away. The Milgard windows that were installed throughout the homes work flawlessly and look fantastic. The windows were custom fit and are obviously very high quality.

Rated 5 out of 5 by from Beyond delighted We did what we always did when venturing out on a big budget project. We did our research, we asked around to friends and family, and got our three quotes. Not only were with pleasantly surprised that the company we loved and felt most comfortable with, lucky for us, it was also the lowest bid. Doug was extremely knowledgeable and didn't give us BS sales pitch. Doug and his team at 1st Windows were on time, professional, respectful of our space, and clean. We had our windows installed close to the holiday season and Doug partnered with us to ensure it was seamless uneventful process. 1st Windows was a pleasure to work with and we would whole-heartedly recommend them.

Rated 5 out of 5 by from Fantastic Pricing I saw them online and starting pricing my windows. I did my homework and read their reviews. After I ordered John called me to go over my purchase to verify building code, which way windows were to slide, etc. They had the best price and good service. I will recommend them to others. Dan
