Sash adjustment possible for Pella double hung windows?
Hi, I have Pella double hung windows that are approximately 15 years old. They are the old double pane design where the inside pane could be removed to put blinds or mutins between the glass panels. As long as I can remember the sashes on a couple of them do not line up where the window latch is. The lower sash sticks up about 1/4+ inch higher. This creates a problem in the winter. It creates a small dam where a lot of condensation forms that then wicks up between the glass panes. Does anybody know if there is an adjustment to fix this? The windows do open and close fine so I don't think it's a problem with window squareness. I called Pella today and they indicated the windows are no longer in warranty. They want $100/hour to come look at them.
