Cal Coast Window & Door

We recently had eight windows and a sliding door installed by Cal Coast Window and Door, and the…read moreentire experience was outstanding from start to finish. 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. They worked hard, respected our home, and left everything spotless when the job was complete. 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!

Window Replacement Center

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.

Great price, fast service. They took the time to make sure our new windows were up to fire code.read more

I received a quote from Ram to replace windows in a rental until in San Francisco. Ram provided the best quote by far and, therefore, I decided to replace the windows in all 4 apartment units. Ram was able to install different types of windows, including single hung and double hung, depending on tenant preferences. Ram is honest, reliable, and an excellent communicator. My tenants only had good things to say about working with him. If you need new windows in the Bay Area, hire Ram. It was one of the best customer service experiences I have ever had and the work and materials are exceptional quality. read more
