Have the channel balances shot past the sash, to the upper corners of the window tracks? If so, then yes, the issue is likely the Top Sash Guides are broken and need to be replaced. When these nylon pieces in the top corners of the sash break, there's nothing to keep the balances secured with the sash. If you could remove an undamaged one, perhaps from an identical window, and show us pictures of it from the front and side, we'll do our best to ID what you need. |
