Aaron and the crew at 406 Window Co. are great! They are pros at following up on product quality and ensuring the best possible finished product. I love window shopping at 406!

406 Windows are an outstanding company to work with. They provide a wealth of window knowledge and many years in the industry that is priceless when dealing with products as important to the value and energy efficiency of your home as windows are. Their customer service is amazing!

Aaron with 406 Window Co. did a great job helping me pick out windows for my house. He took the time to explain all the options and styles that would work and look good on our home. Aaron followed up with us along the way to answer questions and to make sure we were absolutely happy with our selection. We love our new windows and would highly recommend them to anyone looking for new windows.

My husband and I want to highly commend 406 Window Company for its high quality windows and doors; helpful, informative, and constructive guidance in helping us order what was best for us; and outstanding employees who are professional, effective, knowledgeable, skilled, friendly, and kind. Because of 406 Windows products, our home is warmer in the winter and cooler in the spring, in addition to being quieter and more beautiful. Next spring we will be ordering windows for the rest of our house because we are so impressed with 406 Window Companys high quality products and outstanding employees like Ernest who delivered the windows and door to our home in Bozeman and Patrick and his crew who installed our windows and door.Sincerely,Catherine and Mike Legge

Excellent service! If you want a very well built warm window, ask Aaron about the Alpen window line. We love ours, we only used 200 gallons of propane that first winter.

Extremely knowledgeable. These guys are a pleasure to work with on a weekly basis!

Vast knowledge in windows and application. Outstanding customer service you won’t find at the big box stores.
