Thanks for posting! When a window can't seem to stay open under its own weight, the problem definitely lies with the balances. Replacing is a painless procedure; you can see a video tutorial on our installing and removing channel balances guide.
If you aren't sure what balances you need to purchase to use as replacements, you may upload a few pictures of your balances so that we can identify them for you.

Unfortunately, there's no way to adjust tension on channel balances. It sounds the stamp option isn't correct. What is the weight of your sash compared to the options you selected?

Just to make sure, are you weighing the sash or the balances? You need to weigh the sash to determine what option is best, not the balance.

You will have to remove the sash from the window and place it on the scale. Check out the video below to see how you can removed the sash.
