My windows are hard to open

Hi -

My house is about 20 y.o. and most of the windows are hard to open. I've attached some pics of a sample window that needs to have the spiral balances replaced. Pic #5 shows the right side shoe with screw, pic #4 shows the left shoe broken, pic #3 shows the plastic pieces broken off from right bottom of sash, pic #2 is the bottom left of sash, pic #1 is of bottom right of sash. My sash weighs 24.4 lbs, length is 37", and 3/8" diameter. I need to have two windows fixed (4 spiral balances). Please advise me of what parts I need to repair them. 

Thank you,

Hello, Tom. Based on the measurements given for your spiral balance, I would recommend the S900-37. Just make sure you're measuring the outer tube when getting the diameter, not the spring itself.

As for the pivot bar, we should be able to supply a good match for this part, but I would like to see a picture of it removed from the shoe before I recommend anything. I specifically want to see the design of the front tip. Please also make sure that the version you show us is the undamaged one.

Finally, if you also needed a new pivot shoe, then I will need to know its exact width and thickness. You may find it easier to measure if you remove it from the window first.
