What They Say
Good product backed by Milgard Lifetime Warranty warranty
I bought Windows over 5 years ago from 1stwindows. I had a issue with one of the picture windows glass so they set upped the service request. Some confusion setting up appointment time, but problem resolved to my satisfaction. Would recommend Milgard to anyone looking for windows or doors. Altadena, CA (Los Angeles County)Window Replacements
Our home is 20 years old with Milgard windows. A month ago we had a window that was fogging. The service technician replaced this window and we had a question about another window. He looked at this window and said it should be replaced. He then said while I am here why don't I look at all of the windows in the house. He did this and ended up with a list of 12 to 15 windows he thought should be replaced. They have all been replaced.It is nice to know that Life Time Warranty means Life Time Warranty to Milgard. No fine print or other stipulations. Can't go wrong with Milgard.
very professional
