Repair Alcoa Windows

Thanks for posting. We should be able to help, but before I make any recommendations it's important to note that Aloca used many different kinds of parts over the years. There are a few possibilities I can name off the top of my head but I highly recommend that you compare your installed hardware to our product dimensions and information to confirm that everything matches. There is no specific line of hardware only used for Alcoa; like many window manufacturers, they mostly used generic parts.

Now, let's start with the spiral balance. The outer tubes don't affect their function necessarily. If your windows can't stay open, the springs have lost their tension either because they are old and shot, or simply because they need to be recharged. Since your outer tubes are broken, anyway, I figure you want to replace them altogether so let's just assume the springs are shot and the whole balance needs to be replace. Start with our Series 600 spiral balance, which has an outer tube diameter of 5/8". If that matches the diameter of your current balance's outer tube, you should be good to go. All you have to do now is choose the correct length and tip color, which represents spring strength. If your old balances don't have a colored tip, you'll need to weigh your sash on a scale. Please also note our balances have metal tubes, not plastic.

As for the tilt latches, you could have our 26-244 and 26-243, but this is just an educated guess. Like I mentioned above, you will need to confirm that the dimensions and style are the same. If not, we will need to see pictures of one of your old latches. I will also need detailed dimensions.

Finally, for the seal of your sash frame, I recommend going to your local hardware store. They should be able to recommend a good grade caulking.
