We recently had our windows replaced by XO Window Systems, and I can’t say enough good things about the experience!From the very first consultation, the team was honest, professional, and extremely knowledgeable about window replacement options. They walked me through everything without any pressure, which made the entire process so easy and stress-free.The window installation itself was flawless—on time, clean, and done with real attention to detail. Our home looks more beautiful than ever, and we’ve already noticed a big improvement in energy efficiency. The house feels more comfortable, and our utility bills have dropped noticeably.If you’re in Laguna Hills or anywhere in Orange County and looking for energy-efficient window installation from a company that truly cares, I highly recommend XO Window Systems.

We had XO come out to replace the windows in our home, and the entire experience was outstanding from start to finish. Amir led the project, and let me just say--this man knows his craft. With years in the industry under his belt, he walked us through every detail with total confidence and clarity. No hard sells, no pressure--just honesty and deep knowledge. What really stood out was how Amir approached our house like it was his own. As a family man himself, he gets what it means to build a home--not just a structure, but a safe, beautiful space you actually want to live in. The windows look incredible, the install was fast and clean, and the team was respectful every step of the way. If you're considering new windows, XO is the way to go. And if you can, ask for Amir--you'll be in the best hands.
