1stWindows.com is rated 5.0 out of 5 by 40.
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 this dealer has a high level of product and installation knowledge. California Distribution Center, unlike most of the suppliers I have used in the past, had very little product knowledge, and zero when it came to installation. This dealer has no problem meeting me at the more difficult projects to insure that the right product is selected, not only for my customer, but also for the site conditions. Another benefit is communication. Not only am I informed of the lead time, but they call me ahead to remind me of the delivery date and of course when the product arrives. I have found their pricing to be very competitive, and have , for the most part, discontinued getting alternate quotes from previous supplies. Lastly, I have recommended California Distribution Center to other contractors as well.

Rated 5 out of 5 by from Longevity There are many positive things I can say about 1stWindows.com and their staff, but the bottom line is that I have been successfully doing business with them for over a decade and will continue to do so because of their professionalism and excellent service.

Rated 5 out of 5 by from I would highly recommend 1st Windows. I have been purchasing from Doug at 1st windows for several years now after he was recommended by a friend. He is very knowledgeable, honest and reasonable. And if there is a problem he is always a phone call away.
