what a great decision! we are very pleased with our new windows (28 of them!), they've made such a difference in many ways (heat, light, etc); our experience of the process was excellent as well December 16, 2012
This dealer went beyond my expectations. I was impressed with their showroom. I was able to compare the different types of Milgard products first hand. December 4, 2012
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. December 3, 2012
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! December 3, 2012
The sales representative was very knowledgeable answering all of my questions. I was impressed with the dealer's showroom. I was very impressed with Mountain States Building Products' showroom. Being able to compare different windows side-by-side was important to me and my wife. I will definitely recommend Mountain States to my friends. December 3, 2012
Mountain States has been a reliable resource for me and my customers I have found the MountainStates has maintained a professional environment for me and my customers and has consistently been a price conscience advocate for them as well. I look forward to working with them in the future. December 3, 2012
Picked up the phone, no computers, always fast replies. I researched the market for 2 months looking for the best American window that was 1. not plastic or wood 2. had thermally broken glazing system 3. triple pane 4. had real gaskets. 5 sadly my client wanted double hung We're Rocky Mountain Passive House. We normally don't use any American made windows in our buildings. They're not good enough. When compromising overall u-value and going American, Milgard fiberglass is the best price, performance of any American made window. The ultra double hung, triple pane, t &t, is just better quality than the other big manufacturers. November 26, 2012
