Rated 5 out of 5 by from A great product and great service. I am very pleased with the quality of the product, the customer service and the installation. Everything went smoothly and right on schedule. I especially enjoy the SunCoat MAX UV protection as well as the ease of operation of the windows and the sliding door. My house was noticeably cooler during the summer months and is much warmer this fall. I was pleasantly surprised at how much quieter it is too.

Rated 5 out of 5 by from Professional and thorough I was looking at windows but was unsure if it was in the budget this year. The Mountain States rep took a lot of time to explain my options, even though he knew he might not get the quick sale. When we were ready, he visited and discussed all the vendors and prepared several quotes. I never felt rushed to make a decision or pressured to work with him. We are very happy with the product and I would definitely recommend Mountain States!
