Assistance on removing a non-tilt spiral balance

Question

I have General Aluminum non-tilt windows with spiral balancers in my house which was built in 2001. The sash is not removable from the frame and there is no access to the bottom retainer for the spiral balance. How can I replace the spiral balance in these windows?

Hello,

A non-tilt window using spiral balances usually uses wither our (3/8") S400 or (5/8") S500 replacements. You will need to remove the balance to confirm the length and diameter of the balance tube, as well as the tip color at the end of the tube to choose the correct replacement. Take a look at our guide for installing a non-tilt spiral balance here. To remove your balance, you'll essentially need to reverse the steps for installation. Unscrew the balance from the top of the jamb and carefully unhook the balance attachments from the bottom of the sash. I suggest using needlenose pliers to keep a good grip since it could still be under tension. Once the balance is loose, you should be able to pull it through the top of the jamb. Thank you!
