Thanks for posting! I'm sorry to hear you're having so much trouble. Actually, adding a stronger balance than was meant for your window sash will make it harder to open, not smoother. I can help you determine what coil balance you'd need, but I just need to know a bit more about what you have.
If at all possible, can you give me the weight of your window sash? Can you also send a couple pictures of an undamaged balance still in the window track, if possible? Let me know! |

We would have to know the weight of your sash before we can say whether or not it's a good idea to upgrade to 7.5 pound coils. If you had 5 pound coils originally, there is probably a reason for it. Like Paul said, if your coils are too strong, your window may be too hard to open.
That said, it's possible that the 5 pound coils were the incorrect choice in the first place. If so, then moving up to 7.5 wouldn't be a bad idea. But we will need to know the sash weight either way. |
