See if you can find the manufacturer's name etched onto the glass or frames someplace, and then contact them. Andersen still provides parts for every window they ever made. Don't know about some of the ohters.

Excellence is its own reward!

Bobeddy,

Did you ever find replacement springs for your windows, or determine what kind of windows they were? I have the same problem, and it sounds like the windows are the same.

Thanks.

I have one window in my house with the Anderson logo on the storm pane. Anderson said they could only sell complete balance assemblies. I did find what I needed at the Blaine Window Hardware Co., Hagerstown, MD. Their telephone number is (800) 678-1919.

The springs I got are longer than the two lengths that I needed, but they are easily cut to the correct length. It isn't easy, but I did figure out how to replace the springs without removing the entire balance assembly.

Blaine also has the "feet" - little plastic keepers that hold the bottom of the spring to the bottom of the sash.

Thanks. I'll be passing through Hagerstown on Friday and will stop by.
