We called up Advanced window products after hearing Joe (a sales guy at Advanced Window Products) being interviewed on KTAR. Joe promptly came out and discussed with us how getting new windows would save on energy costs, cut down on the heat in the summer and the cool in the winter and as an added benefit, the noise as well. We had Joe measure the windows while he was here and he gave us a quote. We had already received a quote from one of their competitors-but were leery about using the competitor after looking at the reviews of said company. Joe's bid came in higher, but through negotiation, we came to an agreeable price to replace all of our windows and two sliding glass doors in our house. The following week, the production guy came out for very accurate measurements for all of the windows and they were ordered in November. We set up the install date to coincide with the the days we'd be working from home in the first week of January, 2026 Martine and Mario were our installers-and they were amazing! They definitely "know their stuff" and were a pleasure to be around. Our install took 2 1/2 days due to some inclement weather. Martine and Mario were always cognizant of dust and debris and were constantly vacuuming and sweeping up around their work area. They also took their time to make sure everything was right-and when they were finished they explained how every window and slider functioned. About the only negative was that the installers were delayed-and Advanced Window Products office personnel tried to call us the day before (due to the inclement weather) and let us know, but the call went to our spam inbox on our cell phone. It would behoove Advanced Window Products to somehow 'tag' their phone number so that the company is identified on the incoming call. I don't know too many folks these days that answer calls from numbers they don't recognize! That being said-if you are looking for new windows that both the glass and the frames are made locally-Definitely call up Advanced Window Products. They will be our 'go to" for any future window needs-and they should be yours as well! BTW, did I mention that Martine and Mario rock? - 1/25/2026

Installation crew was amazing! Miguel and Daniel removed old windows and installed the new windows with great care for our home, furniture, and pets. They left everything clean and perfectly in place. Thanks for everything Miguel and Daniel. You two are the best! - 1/24/2026

We have lived in this house for over 20 years and the seals had broken on a couple of our West facing windows. For the last few years we have just been living with the unsightly streaks from condensation between the window panes. We have had many window salesmen try to get us to buy replacements but we usually did not qualify for their sale as we did not want to replace very many windows or the price was outrageous. Advanced Windows was willing to replace just the ones that needed it and at much better pricing. But the most important selling point was their local factory in Salt Lake. They manufactured the exact windows we needed replaced, which were all different sized arched windows, and they all fit perfectly! We love the quality and the huge reduction in heat transfer from the kind of glass they use, especially in those West facing windows that just get blasted with the afternoon sun! The installers were both super polite and extra careful to keep our house clean and they did an excellent job. We are so happy with the windows and the whole installation process. We highly recommended this company to anyone needing window replacements! - 1/24/2026

Great experience with Advanced Windows! Professional and experienced office staff to help with payment, financing, and scheduling. Installation team Brock and David were on time, quick, professional, and friendly with respect to us, the dog, and our home. Less than 4 hours to replace 12 windows in our 1959 home. The windows are quiet, easy open and lock, and look great! Yes, i would recommend this product and company to anyone needing a more efficient home. - 1/24/2026
