We needed to replace failed double-pane bay windows in our 1911 Edwardian and after 3 disappointing bids (confusing, un-professional, late) I called Gilberto Arellano. Best call ever! Gilberto came to our house, measured, presented a bid on the same day, and met every possible hope and expectation. He was helpful negotiating our vision of colored glass, tempered glass and design elements. On the day of installation, three professional craftsmen arrived and six hours later, after focused shaving and fitting, our three double-hung windows work to perfection. Gilberto Arellano and his team of craftsmen know precisely the art of wood windows in San Francisco. Dream project!

I like fixing things in my house myself when I can, but when two of my original Victorian…read moredouble-hung windows from 1900 broke, I watched exactly one YouTube video and knew I needed a professional to resolve the issue for fear of making mistakes. Their rate was very reasonable and they were able to come quickly (a godsend with the various heatwaves we've had recently) and fixed the sash ropes so the windows now work well and you wouldn't even know they were once broken. Eventually I may want to install new windows (that match the previous style) in my bedroom due to noise disturbances from outside, and I won't hesitate to reach out to Gilberto Arellano Windows to assist with that project as well.

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.
