Rated 5 out of 5 by from Look good! Function smoothly! My Milgard Trinsic Series windows were just installed. It took me many years to replace my old windows. I wish I'd done this sooner. The new windows look so good and function so well! I particularly love the Pureview Mes screens. They almost disappear!

Rated 5 out of 5 by from Just replaced old window glass I called Milgard about our in window glass that went foggy between the glass panels. I was worried they couldn't replace it because so much time had lapsed. But the service department found our exact window and ordered the replacement form the original specs. Marco came today to replace the glass. It took 15 minutes and he was very knowledgeable and helpful. The new window is clear and was a perfect fit. Milgard is wise to make a product that last for a long time (10 years) and is easy to replace faulty parts.

Rated 5 out of 5 by from Guaranteed for life replacement We have had Milgard double pane final windows for 17 years and have been very pleased not only with the windows itself but with the guarantee for life policy. One of our windows developed a leak causing rust formation on the inner window. Milgard came out and replace it on time and very efficiently free of charge. Thank you Milgard!
