We ordered windows for a new home build. All of the windows and screens are warped and don't close properly. Northstar sent a repair man to come and repair brand new windows. We are on a very short time line to have this problem resolved and Northstar is taking their time getting back to us. I truly hope they do the right thing and replace these windows, although, I am very doubtful that they can supply a quality window from what we have now seen. The windows we received should never have left the factory in that condition.
