1stWindows.com is rated 5.0 out of 5 by 46.
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 The Best Window Installer!!! Doug at 1st Windows did an absolutely perfect job. They were fast and efficient. The windows look fantastic, I just love Milgard. The crew sealed off any dust they might make and were very carful with not tracking dirt anywhere When they cleaned up after the job was done, my house looked even better than if I had cleaned it. It is so nice having good reliable windows. They are beautiful and look like they were always there. Doug Lopez is a wonderful guy. Sue Horwood

Rated 5 out of 5 by from Superior Dealer 1st Windows worked hard to get me the windows I wanted. They have excellent communication skills and always had time for me on the phone. They happily made changes for me and reviewed my complicated order with me one final time before submission to make sure my order was correct.

Rated 5 out of 5 by from Amazing Customer Service The best part of our experience with Milgard is their constant communication from obtaining the quote to the final product. They aim to make sure we, the customer, are satisfied with their product and performance.

Rated 5 out of 5 by from Good source for windows and other hardware I have been using 1stWindows for the past 7 years, and I keep coming back because the owner, Doug, takes care of his customers. I had the windows in my entire house replaced with Milgard, as well as two slide doors, at a competitive price, and they have held up well. Besides Milgard, 1stWindows is also a good place to purchase hardware, including door levers and locks. I have high expectations for the vendors that I choose work with, and I would not hesitate to give Doug my business or my full endorsement. Give 1stWindows a try, you will not be disappointed!
