Window balance hard to close

Hello. I believe I have windows the balances S751-34 33HD. Most of the windows are hard to open and close, but especially close. Would replacing the balances improve this issue?

It's possible your balance springs aren't up to snuff anymore, yes. The older they are, the more likely that's the case. Before I say anything for sure, though, can you tell me the weight of your window? I'm also thinking maybe it could be that the 33HD stamp isn't the best choice.

Two balances with that stamp can hold a window sash weight of 24 through 29 pounds.

Thanks! The windows are original and about 18-19 years old. I don't know the manufacturer. The stamp inside the window has "ws igcc. igmac WS Med"
I do not know the weight of the windows.

You will have to remove the window from the sash and place it on a scale to determine the weight. Any common bathroom scale should do.

Hi. I realize this is an old post but I finally got around to the window project again. The weight of this window is 11 lbs. Which balances should I purchase to replace these 33 stamped ones? Do I also need to purchase the feet?

Hey, good to see you again. This balance will have to be custom made, since your window is so light. I'll go ahead and email you a purchase link and price quote for your review. Please let us know if you have any questions!

Thanks. I don't believe this is a ribbed channel balance though. Does that matter?

It does, actually. In your first post, you said you had a Series 751 channel balance, which is ribbed. Can you confirm what Series you have? If you want, you can take pictures of it and post it here for us to see.
