How to tighten sash balance

Not all balances can be tightened up, so to speak. It depends on what you have. Can you show me a photo of the balance in question? You may want to show it to us out of the window. If you can't tighten it up then you'll have to replace it, and seeing it removed from the window will allow us to ID it.

We may need more photos after that, but I'll have to know what to ask for first.

Hey, Jack. I can see your sash clearly enough, but not your balances. Can we see them, too, or are they missing?

These look like pretty old wood windows. There is a good chance we won't be able to supply the specific balances you need, but I really can't say for sure until I see them. Let me ask you: are they just exposed springs sitting in the jamb track? If so, then we definitely can't help. You'd need all new jamb liners in that instance. If that's what you have, I recommend contacting a local mill work who still makes wood windows for assistance.

If you have any other style, though, then we will need to see the original balances in order to give you advice. All I can tell you with these photos is that you have wood windows.

Thank you. I can see that this is a kind of tube balance, but the bottom part is cut off. That is an essential detail, since it shows us how it connects to the sash. Can you show me a clearer picture of that bottom end?
