Replacement coil balance

Hi, Bryan.

It looks like your coil spring may have broken and snapped which would explain the loud noise you heard. We can help but we would need to see an undamaged pivot shoe removed from the window in order to ID the compatible coil springs. Take a look at the videos we've related on this page and let us know if they help. 

Thank you for the additional photo! It appears your pivot shoe is a match for our 15-215 which is used in the Series 140 coil balance assembly. To determine what coil weight option is needed, look for a code on the band of the coil spring. If there aren't any, weigh your sash on a scale and tell me its exact weight. I can calculate what you'll need from there.

Hello! If your sash is 17 pounds then my recommendation is the S140-9. A pair of these assemblies will carry sashes weighing 17 through 18.99 pounds. Just note that they are sold separately. 

You can see a detailed price breakdown on the store page linked to in my previous response. We do ship to Canada, but I unfortunately don't know how much shipping would be off the top of my head. I can tell you that the cost will be calculated for you automatically during the checkout process.
