I've been thinking about replacing my windows for awhile now but never quite got around to it. I was in a customers (I'm a handyman) home a few days back and noticed just how much nicer it felt in there since they had replaced their windows with the new energy efficient glass. A few days later a young man came to my door and gave me his sales pitch. Usually I just send them on their way, but somehow I liked his demeanor so I heard him out. Then after talking motorcycles for a bit, I agreed to meet with one of their sales reps. They called the next day and set up and appointment. At the appointed time Cassidy King came by and walked me through how their windows are manufactured and how she would take measurements of all of my windows and then give me a price that would be out the door so to speak. After that they would send out a fellow to take very accurate measurement and then they would build them custom fit to my home. When the build was complete (only a week or two as I recall) they set an installation appointment. Five guys showed up and went to work, positioning each window at the correct place it needed to be. Then they started removing the old windows and then installing the new. Having been in the trades for so many years, I watched them install that first window from start to finish. I was so relieved to see that they did it exactly as I would have done it myself. These five guys worked like a well oiled machine and each one knew exactly what his job was and they did it. It wasn't until they had cleaned everything up that they called it a day.At the end of the day all of the windows had been installed and the difference was felt immediately noticed. I no longer hear the cars that use my street and the F-35's flying overhead are now hardly noticeable. The next day a crew of two came back and trimmed everything out on the inside making everthing look great. I'm now on my third day of enjoying them and I notice that my A/C unit is cycling much less often then it was. Although I don't think I will need it, the lifetime warranty is a nice thing too!

A Pleasure to work with from start to finish. Ordered my windows in the late summer from Ken and recently had them install by Don & his crew. They did all 11 in 1 day.

Brad and Heliman installed our new windows and were fast and kind. Brad caught a measuring issue with our new sliding glass door… it had to be re-ordered and installed at a later date but our installers and the company handled it for us with no other issues. We are very happy with the customer service, installers and product. Thanks to Brad and Heliman for taking such good care of us.

Getting new windows was actually a fun experience, believe it or not. Jordan is not a typical pushy sales person. He provided information, options, and answered questions without pressure. He really cares. The installers were also kind, respectful, and hard working. We enjoyed having them there and visiting from time to time. Our house is a little unique with a pitches, slick, metal roof. Javier got up there in his bare feet and took care of business. He and Willy worked so well together. Willy called to let me know about times and check on things. Thank you everyone!!!

Amazing Experience from Start to Finish – 5 Stars! We recently had windows installed by Advanced Windows, and I couldn’t be happier with the whole process. From the initial consultation to the final installation, everything was seamless and professional!!

Great windows! I replaced older style windows that leaked air and noise. The new are awesome. I get less draft and it’s so much quieter in my house. Also, they look great. Highly recommend!

These new windows are gorgeous! It's amazing how much better the world looks through them! I thought we were buying these large picture windows for the better energy efficiency than the 50-year-old windows that were there, but they also are somehow giving a better view. The team was very easy to work with; the sales, scheduling, office, and installation teams were all courteous and prompt. The installation team left the house almost cleaner than when they arrived, and they were finished in just one day. I know these comments all sound really too good to be true, but I am really pleased so far.
