After looking at multiple companies to replace all 23 of our home windows we decided to work with XO Window Systems; and it was the best decision we could have made. Amir not only gave us an amazing presentation, but gave us the details we needed to fully understand the product, service, and installation process. We considered a few companies and found a better quote, but Amir stayed in communication with us and matched it. So the decision was a no brainer. A job we thought would take 2-3 days, ended up taking just 1 day! His install team are all professionals who worked fast, and provided top quality installation. They were efficient, cleaned up after themselves and made sure everything was installed as planned before they left. Highly highly recommend.

I feel incredibly lucky to have found Amir and his team for our window replacement! From the start, communication was straightforward, and the pricing was very reasonable. A huge green flag was that they adhere strictly to California contract law by only requiring a 10% deposit. Something we found many other vendors don't do. The installation itself was seamless. The crew arrived before 9 AM and managed to replace 9 windows, including a sliding door, in a single day, even on an unusually hot February day. What really impressed us was their custom work. We had a difficult-to-find "sunburst" grid pattern that three other vendors told us they couldn't match, but Amir’s team replicated it perfectly. They also went above and beyond for us. We asked if they could caulk some gaps near our front door, and even though it wasn't their job, the crew happily took care of it and did a beautiful job. The finishes are highly professional, and my wife and my parents are absolutely thrilled with the results. I wholeheartedly recommend their services!

Truly legitimate company on both the management and installation sides. We recently moved into older house that was not very well taken care of and have been working on renovating it step by step. It came time to replace 3 windows (one of which was quite large, 2-3x the size of a normal window) and 2 patio doors. This was a larger project and of course I did my due diligence in talking to multiple companies before making a decision. Almost at the last second I stumbled across XO Window Systems at the recommendation of a window screening company that helped with the windows that did not need to be replaced (WeScreen, another fantastic company). Grateful to Viviana at WeScreen for her recommendation, because we have absolutely no regrets with choosing XO Windows. Scheduling the initial assessment was painless and Amir was efficient and professional. I've grown up working on houses and at the end of the day what I am looking for is quality of character. With house renovations it is unrealistic to expect that everything will go as planned, and what makes or breaks an experience is how things are handled when issues inevitably arise. After spending some time walking through the project with Amir I was more than comfortable with having him and his team move forward with the project. Amir’s pricing was also a bit lower than the other company I was considering, so that helped solidify the decision. The installation day itself was relatively uneventful, which is how we like it. The guys that came out were polite, efficient, and pleasant around the wife and baby. They also notably got along well and had good teamwork as they grinded out the demo and installations (9a-6p). They went above and beyond in helping with some small peripheral issues and were conscientious about keeping the surrounding areas clean. The foreman Salvador was sharp and had excellent awareness of the project as it developed. Massive thank you to Sal, Rigo, Ray, Eric, and Jesse. Will definitely be giving Amir a call in the future.

Frequently Asked Questions

How long does a window project take?

XO gives a typical 4–8 weeks from order to installation; installation itself usually takes 1–2 days.

Does XO help with permits?

Requirements depend on the city and scope of work. XO can assist with pulling permits or guide homeowners through applying themselves.

What happens after a homeowner accepts a quote?

XO prepares an electronic work order, schedules a measurement appointment and places the order, then schedules installation around the shipping date after manufacturing.

Does XO create new window openings?

No. It does not take on major construction such as creating new window openings; that work requires a general contractor.
