Rated 5 out of 5 by Excellent customer service.. Everyone we dealt with was extremely helpful. I would recommend South Valley Windows and I would and will use them again in future! thank you for all your help!!! May 21, 2015
Rated 5 out of 5 by Absolutely Great Experience We initially received quotes from three window companies for our whole house window replacement project. South Valley windows stood out from the others in several ways. First and foremost was product knowledge and their thoroughness answering my many questions about the installation details. Second was their very competitive pricing. Joe was very confident about the high quality of the Milgard Tuscany product line and we felt reassured that South Valley Windows would do a great job. They delivered as promised. Their timing was right on schedule, and the installation team of Mike and Jacob did a fantastic job. No detail got overlooked, they worked efficiently and we were surprised with how quickly and cleanly the entire job went. A total of 12 windows and a wide patio door were done in about 1-1/2 days. The job looks perfect and we couldn't be happier. South Valley Windows are an excellent and competent company to deal with and we had an absolutely great experience. April 17, 2015

Rated 5 out of 5 by Very pleased with my experience! This is the second time I have hired South Valley Windows to complete a replacement window job. We were so happy with our first experience that when we bought a new house we wanted to again hire the window company that was helpful, gave suggestions, who was prompt and went the extra mile to get the job done. I have highly recommended South Valley Windows to my friends who are also very happy with their results. I will do business with this company again. February 14, 2014
Rated 5 out of 5 by This dealer has great customer service and a pleasure to work with My first opportunity to use this dealer was 14 years ago when we first moved to Gilory. we had about 5 windows replaced. We wanted something new that was modernized, and custom. They did an amazing job back then, very professional, prompt, and knowledgable. So, last year when one of our windows broke we knew we needed to replace the entire window not just the glass. I remembered the company (since we live in a relative small town), and contacted them to come out for an estimate to replace the window. To my relief it was still the same owners and same great service (and yes they remembered me too!) . I not only had a new replacement window put in, I had two others replaced as well. I highly recommend this company - :) January 16, 2014
Rated 5 out of 5 by Absolutely great in every aspect From beginning to end, Joe and his team helped us find the right windows, installed them, and followed up to make sure we were happy with the results. His team was courteous, efficient, and great at listening when we had questions. I would invite them into my house any day. We are extremely pleased with South Valley Windows and will use them again for any of our window or door needs. January 16, 2014

Rated 5 out of 5 by Best window company around! I recommend this company to anyone that I know is interested in new windows. They have a friendly "family type business" with great customer service and excellet pricing. The estimator is very knowlegeable and helped us pick out just the right style windows for our craftsman style house. The girls in the office are very friendly and knowlegeable as well. I have seen many window companies come and go, but this is a quality operation that will be around for a long time because of their excellent work, great prices, and wonderful customer service.

Rated 5 out of 5 by South Valley Windows were the most informative! Joe at South Valley Windows knew his product! He answered all of my questions and then some. They had great displays set up so I could actually see what he was talking about. Regina was very prompt in returning my emails when I had further questions. I love to shop but not necessarily for windows....... the people at South Valley Windows made it a pleasurable and informative shopping experience! Thank you Joe! October 24, 2012
Rated 5 out of 5 by Professional, expedient, expert advice, top notch service! We worked with Paul one of the 2 co-owners. He was courteous, kind, and patient with every last question we had when replacing all of our windows for the first time since building the house 24 years before (we had lots!). The workmanship was excellent. We had plenty of time to course correct with Paul and the installers anything that looked a little different once installed than it was when we ordered it. Paul gave us pricewise advice for things we were not sure about (replacing one window with French doors vs. sliders for example), and walked the house a few days after the job was done to answer any questions and rectify and flaws, answer any questions. The windows are beautiful! I'd highly recommend South Valley Windows. September 13, 2012
