Discontinued Louisiana Pacific window problems

It sounds like there may be a problem with the window balance. I will need pictures in order to help you. First, take a picture of the window itself. That is a good place to get started. Please also try to get a couple pictures of the balances; they should be located inside the jamb track on either side of the frame. They may be in a metal or plastic casing and they contain the springs and pulleys that are supposed to hold the window up once you raise it.

I do believe we can help you repair this window, however we are having trouble finding an exact match for this balance. Is it possible to see the balance removed from the window to get a better look at it? It appears that it could be similar to our Series 770 but I'm not sure. I would also like to see what type of balance shoe you have, but the one you show is damaged. Do you have one that isn't? Send us some more photos a long with dimensions and we should be able to identify the parts needed. Thank you again for your patience!

Thank you for your patience. From what I can make out so far, I think you have some version of our Series 770 channel balance, though it may not be the same. You may also have a 15-129 pivot shoe. It's still hard to tell. I recommend watching the videos I've associated on the right side of this page. They may help give you some insight on what you can do.

Thanks for getting back to us, hopefully we can help. The pivot cam in the tilt shoe might be twisted in such a way it is grabbing the sides of the window track. Are you able to look up under the sash to see the shoe? If so, see if you can make a hook-like tool out of a coat hanger to grab and pull down the shoe a few inches. Hopefully that will allow you to tilt in the top sash and remove it. Also maybe spray some WD 40 up under the top sash track.

I'm not sure about the wool pile. Could you use something like our 58-053? It has the same type of kerf.
