How do you get the window weights right?

I have old double hung windows and some of them are not operating as easily as they used to.

The weights are too heavy in some instances as it is very hard to close them and or they might not want to stay closed.

does the length of the sash cord have anything to do with this? I didn't think it did but a few years ago I replaced several of them and I know some of those are the ones not operating correctly.

1) is there a trick to getting the sash cord length correct?

2) what options do you have if the weights are too heavy and how would you determine the correct weight?

I believe you would have to weigh the window then cut that number in half to get the weight of each sash weight. I do not know of any tried and true method to determine sash cord length. I always tried to make sure the weight was hanging a little off the bottom with the window in the full up position. I found that using chain instead of rope makes for a better operating window. You can get kits which come with the chain and other hardware needed that will do about 10-15 windows at your hardware store for around $40.

There are also kits that replace the pulleys, weights, and ropes completely...but I swear, I can't find any at the places I normally look.

They are basically like a tape measure that fits in the recess where the pulley was. Helps seal the window and is normally more reliable.

Maybe someone else can find them. I thought Blaine or Swisco had them online, but no joy.

btw as Bill said, as long as the weight isn't bottoming out, it shouldn't matter
