How or Why does the spiral sash loose its tension if the window has never been removed, only tilted in for cleaning?

Hello,

Window balances are not meant to last forever and need to be replaced eventually, regardless of the amount of use since they are under constant tension. If you need help finding the correct replacements for your window, feel free to send us a photo of your balance removed from the window and we can point you in the right direction. Thank you!
