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!

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.

Once the Windows were built and ready to be installed, the installation manager Lorna was very quick to schedule an installation date and accommodated my scheduling requests. On the installation day, Juanito and Mauricio arrived on time, worked very efficiently and professionally, and did exceptional installation work.

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.

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.

The crew started around 8 AM and finished at 5 o'clock. The Anlin Windows came with Anlin armor, which is the sticker that you removed off the glass so they look perfectly white without all the fingerprints smudges. The building permit process was easy felt like a waste of money. We paid thousands of dollars to the building department and the building inspector came for 30 seconds. All he talked about is our smoke detector and the new batteries that are required along with the carbon monoxide detector. He was very familiar with Golden State Windows and said they did great work after barely looking at their installation. We like the grids squares they added some character to the house.
