old Alenco window repair

Thank you for posting. It looks like your windows are not-tilt, so I think that you either have our Series 400 or Series 500 spiral balances. To determine exactly which, you will need to measure the diameter of your balance tubes.

I will also need you to open the window and send a photo from the bottom looking up where the balance attaches to sash.

Thanks for the additional pictures. That helps clear things up a lot!

Since your balance tube is 3/8" in diameter, I think you may want to consider our Series 400 balances. I can't make out what fitting you need on the bottom of sash, though.

Now, before you remove your sash, your balances might need to be charged with our 75-005 tool. You can see in our guide on charging non-tilt balances below.

If this doesn't help ,then you will need to remove sash to replace broken balance or bottom sash clip.

Some non-tilt sashes are made so that they cannot be removed, it's true. It's frustrating but it can be worked around. If you need to replace the balances in such a window, you just need to drop them in from the top, fasten it to the track, then have someone hold the sash up while you attach the clip at the bottom. It may be a little trickier than it sounds, but as long as you're patient and careful the balances should install with no problem.
