Your balances should definitely be lasting longer than just 6 months. It sounds like the springs you have area not the proper strength for the weight of the sash. Before we go over that, though, let's look at the Series.
Do you think you can use our Series 140 coil spring assembly? This comes with everything together in one kit. Look over the dimensions to make sure it can fit in your jamb track. Also keep in mind you may also need to replace the pivot bar with our 26-398 or 26-405; your old pivot bar may not work with the new shoe. If this can work, you will need the weight of the sash. For this particular Series, you would divide the weight in half to determine the best option. For example, if your sash were 26 pounds, you would want the S140-13. One on each side will support the sash weight. Let me know what you think! |

Great! I'm hoping these work better, too. I personally find the Series 140 to be a sturdy option. Sorry about missing your other question. If your window does not have a previously existing cutout, then making one yourself is definitely possible. Check out the video below, where we detail exactly how to go about this.
