Hi, I have a few windows in my house that have balance systems that are damaged. I'd like to know if they are repairable. Are you able to tell from the pictures attached?

Hello,

We should be able to supply replacement balances for your windows but we'll need to see them removed from the jamb. We've related some videos for removal depending on the kind of windows and balances you have. Thank you!

Carefully compare your balance to our S751 with a 15-014 knife lock shoe. Also, see our video below that will walk you through the replacement process.
