    We are very pleased with Ultimate Installz. The entire team seemed to really care about the work that they were doing. They were very good about staying on top of communication and planning and were transparent in their billing. The installers were great and took time to help answer any questions and provided great follow up. We would not hesitate to use them again and highly recommend them.

    My experience with Ultimate Installz was almost enough to make me wish that my sliding glass doors malfunctioned more often! They come over and they get the job done quickly and cheaply, and with courtesy. Not too many folks out there are qualified to repair my automated glass doors, so of course I was expecting to get squeezed for a lot of money. But nothing like that happens with Ultimate Installz. They are the best.

    I recently purchased a home in Newport and needed some new doors and windows. I was referred by a friend who said they did good work, and so I had them come out and install my new doors and windows. For a small shop, they greatly surprised me in their work and their punctuality. Jayson came in on Monday and had my whole house done by Friday. I was told by other contractors it would be a 3 week process. The doors and windows look fantastic, and I could not be happier. I recommend them to all of my friends and customers for a quality job.

    It's nice when skilled guys arrive to put in your expensive doors and windows. They were pleasant and ready to work. They installed all the windows and doors including 10' tall multi- slides spanning 18'. They got the adjustments just right.

    The Ultimate Installz crew did an great job on my rather large and heavy glass panels windows. It was a difficult job that went smooth thanks to these guys. I highly recommend this company.

    Jason Cruz and his company have been incredible. They have been extremely helpful and knowledgeable. I have been doing upper end residential construction and recommend Ultimate Installz without any hesitation.

    I had a great experience working with Ultimate Installz. They installed six complicated doors for us in Northern California. As is true of many construction projects there were a few bumps in the road during the install. Every problem was handled very professionally with good communication and a beautiful finished product. I would recommend Ultimate Installz for a project anytime and anywhere
