Dear sir/madam,
I have some metal double pane, single hung window sashes that won't stay up. All the existing spiral balances are apparently broken beyond repair. So I'm in the process of replacing the spiral balances, 3/8ths, 30 inch. First window worked fine: on my second window not so much. I replaced one side, no problem. The other side I could not get to work. The spiral would not stay properly engaged in the window bracket. It kept twisting out and scoring/scratching the aluminum jamb when I tried to raise or lower the window. (See photo 031, 034, & 035.jpg)
Some of the old balances are actually missing the brass T-bar at the end of the spiral. But most show T-bars that are tilted about 30 degrees, as if one side of the T-bar slipped out of the window bracket and the other side did not.
I think I'm seeing a cascade failure, starting with the window brackets distorting enough for the spiral balance to slip out.
Fortunately, you sell brackets that appear to match what's on my windows. Specifically:
Bracket, #13 Product Code: 17-010
Unfortunately, I don't know how to install such a bracket. I assume I must remove the sash from the window jamb, but even that operation remains a mystery. I have not found a single YouTube video showing how to remove the sash of a non-tilt metal window with spiral balance. (Lots of tilt window and spring/block & tackle channel balances. But nothing matching my windows.)
Since you sell the replacement brackets, can you tell me ? or point me to a video that will show me ? how to remove and replace a bracket #13, product code 17-010?
Thank you,
Brian
PS: I'm using yellow tip balances because the windows seem quite heavy to me, and the 30" green tip are perpetually out of stock. But I have not figured out how to remove a window to get an actual weight. Please help.

Hello, Brian! It really seems like you have a handle on this project, but I'm afraid I'm about to throw a wrench in your whole operation. Replacing brackets like the 17-010 is very, very difficult. You are right in surmising that the sash has to be removed in order to get at them, but the catch is that the sashes on this type of window were not designed to be removed in any way. In fact, they were specifically designed so that they can't be removed. These are what we call "builder's grade" windows, which are typically older, aluminum windows that are installed en masse. There have been many manufacturers for this kind of window, most of whom aren't even in business anymore, but their general philosophy was the same across the board: when something broke, they wanted you to buy a whole new window, not a tiny, inexpensive repair part. Now, it's not impossible to remove the sash, but it is a huge project. You basically have to disassemble the entire window frame to allow the clearance needed to take it out. This is by no means easy and it is not something I like to recommend. My advice to you is to try to get in touch with a local professional who is familiar with this kind of window and see if they'd be willing to come out and look at it for you. They may even know a trick that I don't, but at the very least they would do the job so you don't have to. I am sorry to be the bearer of bad news, but I hope this information helps direct you as to where to go next in this project. |

You're very welcome. I definitely think that's the best move at this point. Good luck on your project and please let me know if we can be of any help in the future! |

Yes, there is a downside as a matter of fact. If you use a balance whose spring is rated too strong in comparison to the weight of your sash, then your sash will be difficult to close. In a worst case scenario the window would even open up on its own after you walk away. You have to think of window balances like Goldilocks' porridge. Not too weak, not too strong. They have to be just right. Now, weighing your sash will be tricky so long as it's still in the window, but it still works. What I usually do is place a bathroom scale on the sill and gently lower the sash onto it (making sure the balances are disconnected first, of course). The weight rating you get probably won't be 100% precise but I find that it's usually close enough. |
