Really great service overall…read more Response time for initial inquiry for a window repair/initial quote was pretty quick. Scheduling was easy. Communication through the whole process was also easy. Final quote after a visit to double check measurements (which was easy to schedule, and didn't take long) was super reasonable. Turnaround time as far as ordering parts and having it delivered, was within expected timeframe, which was roughly a week. An installation happened quickly, only about 24 hours after I got a call that the parts were in. Would definitely use their services again.

Chris did an excellent job guiding the project and making sure everything went smoothly throughout the process. The installation crew (Manny and Omar) were absolutely amazing, professional, efficient, detail-oriented, and incredibly clean.

If you're looking for a company that provides great communication, quality workmanship, and exceptional customer service, I highly recommend Cal Coast Window and Door.

We wanted to replace all our original 1960s-era single-pane windows with double-pane windows. We…read morealso wanted a storm door for our front door. We got an estimate from Andersen (less the storm door). Their products and installation method were top-notch, but so was their estimated price! So we wanted something more economical. After some research we heard Milgard windows using an "retrofit" installation would be more in our price range. We also wanted a window/door-installation company that gave us a good price estimate (1/3 the cost of Andersen), was in our locale (Tri-Valley) , and had 5-star rating already. So we were happy to find Cal Coast that met those criteria. The initial estimate process was straightforward. Our estimator was friendly and efficient. The format of the estimate came in digital PDF format. It was easy to print, and the details and layout were very helpful with diagrams of what the windows and door would look like with dimensions. One measurement for one window was slightly off. I mentioned that to my estimator. He assured me that was not a problem because if I accepted their estimate, then the next step was for another technician would come out to the house to re-measure the windows more accurately and in more detail. We did accept the estimate, and indeed another technician came out to do detailed measurements. Then we received a revised and more detailed contract in that same great layout! The estimator kindly set our expectations that our windows and door were going to take 5-6 weeks to custom manufacture and about 1 to 2 days to install. Those timings were right on target, which helped us in planning other events in our life. Installation only took 1 day! The crew was great - courteous, hard working, and efficient. They put foam insulation in the space between our window frames and the new windows. The caulking work was professional. I was pleased. And the crew cleaned up after themselves perfectly. Another thing I was pleased with was Cal Coast's production manager helped me apply and get my city building permit for the new windows. The day of installation, the foreman handed me a nice folder with the printed permit with other instructions. I really appreciated that. Also after installation she worked with my city building department to schedule a final inspection by a city inspector. When the inspector came out, because the product and installation were superb, it passed with no problem. Of course, I paid a little more to have this permit processing service, but it was well worth it. Finally, as you can tell from this rather long review, I'm very pleased with our experience with Cal Coast and the Milgard products. I add my 5-star review to others that have gone before me for Cal Coast!

Going into this, my wife and I thought the whole process would be stressful and time-consuming but they made it completely smooth and painless from start to finish. Leon was extremely attentive, responsive, and patient, taking the time to answer all of our questions without ever making us feel rushed. The team was efficient, professional, and showed up exactly when they said they would which, these days, is rare and greatly appreciated. They were also very mindful and respectful of our home throughout the entire installation process. What really stood out was not just the service, but the value. After getting multiple quotes, Window Station offered a more competitive price AND a better-quality product than the others. That combination is hard to beat. Overall, this was one of the best home improvement experiences we've had. Highly recommend Leon and the entire Window Station team you won't be disappointed!

If you're looking for quality products and workmanship, they are the best choice. Valentina was thorough, responsive and helpful with providing the initial quote. After deciding to move forward, I met Guram, who did the final measurements. The project consisted of 6 windows and 2 sliding doors. Guram's team was efficient and finished the same day; the workers cleaned up all of the work site areas. Valentina and Guram were very insightful and knowledgeable about their products. I appreciate that they didn't try to "upsell" us or offer anything we didn't need. We are so happy with our new windows and doors!!! We will be recommending them to all our family, friends and coworkers.

Valentina was very responsive and their service was fast, approximately 3-4 weeks for the windows to be made and shipped after the order was placed. She also offered to price match any other company, but they were already the best price compared to other companies with different window brands. All our windows were installed in one day. We have had the windows for 6 months and there were no leaks during the rainy season. The windows have a lifetime warranty with Milgard.

I remodeled my house in 2009 and had Marvin Windows installed at the back of the house, however I…read moredid not replace the windows in the front of the house as they were newer. In 2025, we decided to replace all the windows and the front door in the front of the house and wanted Marvin windows to match the front of the house. There are many window replacement companies out there that will build and install windows for you. However, we specifically wanted Marvin windows and we wanted to upgrade to the higher end Marvin windows as we had installed them in the back. Mark (the estimator) was very responsive and came out to measure and give us an estimate. We signed the contract and he said that we could expect installation in 3 months. Well, 3 months came and went and it seems our custom made windows from Marvin had some manufacturing issue and were delayed. Ok, so instead of a September installation, we were now we are expecting a December installation. It wasn't a big deal except that I had to restore my living room for Thanksgiving. This delay wasn't Window replacement Center issue, it was an issue with the Marvin manufacturing process. So, why am I giving a 5 star review. The installation was great. Oleg (sp?) was the lead installer and he did a wonderful job. My husband (a real DYI person and a perfectionist) even said that the workmanship was perfect. See attached pictures. They were here multiple days and left the rooms cleaner than when they started. Not a speck of dirt or dust was left. So, they only do new window replacement/installation. Meaning if you want a window where a wall exist, they don't do that. They don't fix existing windows (broken glass, old hardware). Mark did walk my husband through how to get a replacement part on another window were the hardware was rusted. They also don't do painting. You need to either paint it yourself on the inside or hire a painter to do this. Also, most of the installers speak very little English. We didn't find that to be an issue. If I had a question that they couldn't answer, they called Mark right away and we were able to work it out. The installers all came on time and there was even a day that I said they had to be done by 5 as we had a dinner engagement and they left when I wanted. Overall, this was a really good experience and I would hire them again to install any windows.

Alexander was one of them which my neighbor recently hired to replace her windows. I met four window estimators and Alex from Alexander came across as honest, direct and trustworthy. No sales gimmicks, no rebates, and no pressure. And it turned out Alex gave me the best price. I also liked the fact that they came back without charge and fixed a frame problem that my neighbor was having with her new windows. Four months later, Rosy called to schedule an installation date for my new windows. Two days later, Jose, Carlos and two other crew showed up in two trucks on time to start the installation. The installation team worked seamlessly as a team, they first carefully covered the floor and surrounding to protect my floor and furniture. Then they went to work. From demolition, installation, to clean up, it took less than a day for six windows. They were friendly, efficient, skillful, knowledgeable and professional.
