Hello,
I moved into a house where pretty much all the vertical sliding windows are very difficult to operate. The main issue is pushing it down after it's up. I don't know what to do but feel fortunate now to have found this website with great customer service. After looking at some of the videos here, I think I need new channel balance for all the windows, but not sure. None of them have the take out clip, so I ordered a bunch from your site already. To be honest, I'm not sure if that's what I need and if this is the type of window that uses channel balance. Could you please help me take a look at the pictures and let me know? What do you think could be causing the difficulty is pushing the windows down? Thank you.
