Rated 5 out of 5 by from Great job I got the estimate few months ago from joe, he was very professional and friendly very reasonable price. He didn’t do any pushing to get the job and very honest. It felt right from the beginning. I called few times to ask some questions and every time he was very helpful. I changed all my Old windows . I changed my my mind last minutes to different kinds for 2 of them , again joe was very helpful, even the new order was little bit more pricey he kept the original contact $. They finish the job in one day and I couldn’t believe how beautiful it turned out. Absolutely love the new windows! It was a little discoloring on the handle and as soon as I mentioned it, he said he will order the new one. Definitely recommend this company! Thank you south valley windows!

Rated 5 out of 5 by from Excellent and professional work at reasonable pric We had purchased a home in August and had planned several upgrade projects including window replacements. Our long time contractor was committed with a large project and would not be able to do our window replacements before the Thanksgiving holiday. He recommended we use South Valley Windows and gave me the owners phone number (Paul Brummitt). Paul came over and did a sizing estimate, but was also very busy. He managed to commit to getting all our windows replaced before we had a house full of guests for thanksgiving. We had used Milgard windows in our previous home and Paul and his team were experts with their windows. Not only did he live up to his commitment, his team came on time and very efficiently completed the job in 3 days! I am very please with the entire process with South Valley Windows and would recommend them to anyone in a heartbeat. I have another project coming up and intend to use them again.
