Nucleus Windows and Doors are AWESOME!! Just got all my windows changed out in my house since they were over 20 years old and they took really good care of me. From the information in the beginning explaining in detail their window options to the installation, it was flawless!!! Jason kept in contact with me with updates and was even able to help with securing financing. Id definitely reccommend them to anyone, they will not steer you wrong. The windows look great and keeps this hot Arizona heat out my house so it stays nice and cool inside!!! Thanks Jason and everyone at Nucleus for all the help and guidance throughout this whole process and for an amzing product!!

Had new windows installed after being nervous and very hesitant in my purchase, but I am very glad I decided to move forward with it. Jason was very professional and explained every little detail and windows arrived as indicated. Installation also went well, quick, and were very helpful and professional. Cost was even better and highly recommended!

From one small business to another, Jason and his team really went above and beyond. We own rental homes and it can be nerve wracking trying to find a reliable, trustworthy company for such a big investment. Jason went out of his way to ensure all of our questions were answered, showed us different projects, and educated on the different heat scales to show the premium quality of his products. You can trust Nucleus Windows from start to finish, with ensuring great prices, working with our budget, excellent installation, and keeping the workspace clean. I highly recommend and will use them for future needs.

Jason and his team were awesome to work with! Jason was able to work with our schedules and was very flexible from start to finish. We had to do everything long distance and I am so grateful he took his time really explaining everything and accommodated our schedules. The windows are premium quality and look amazing! The house had original windows from the 90's and his team did impeccable work replacing them. The master bathroom window was replaced from the outdated, burning hot block windows to a gorgeous obscure window that really elevates the home. We are going to be getting more windows as soon as we can. I highly recommend Nucleus Windows and Doors!
