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!

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!

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.

He is one of the most honest and quality-focused contractors I have ever worked with. During planning, I spoke to a number of other contractors who wanted to use retrofit windows and just leave the siding in place. Alan took the time to explain the proper way that the building wrap, siding and windows had to interface to get waterproofing, and how we were better off replacing all three if we wanted to be sure we'd fix our problem. Even with this extra scope, Alan's pricing was very fair. Thank god we went with Alan. When they removed the existing siding, they found severe water damage underneath the siding and a subpar earlier repair job. When this surprise came up, Alan talked us through the damage and gave us our options. They ended up ripping up two layers of existing siding, cutting out damaged building sheathing and replacing it with new plywood, before proceeding with the job. The overrun costs were very reasonable and we never felt like Alan was taking advantage of us. The end result was great quality at a fair price, and peace of mind that our issues have been resolved and we won't have to worry about the front / roof for a long time now. I would definitely hire Alan again and would recommend him to anyone looking for this kind of work.
