Repairing Double Hung Sash Cords

Restringing the Sash Cords – A Couple of Options

while you are out of the room, you'll need to cover your window.  You could put up some plywood but for a short duration i've just rehung the curtain that will keep the leaves and birds out. If you need to do this over night you'll need something more permanent.

 

 

While Waiting for Clean Pulleys, Restring the Sash Cords

option 1 - the simplest way to get the sash cord back through the window wells to attach back to the sash weight is to try and weave the cord down through the pulley hole, grab it at the bottom and then pull it through. In this case i attached a small fishing weight to the end of the sash cord using a little duct tape to give gravity a chance But after much fussing around that did not work - too much plaster and insulation in the way. So we need to get a little more forceful.
option 2 - that ended up working - was to use a straightened coat hanger a to force the hanger down through the pulley hole , attach the sash cord, and then pull the cord back up. This was more successful but took more time, fewer high strength coat hanger's around nowadays and more time required to straighten out the hanger appropriately. A couple of vice grips or needle nose pliers help this process but means a little a more complexity and tool load.
push the hanger down through the top opening and ....

 

grab it as it comes out the bottom, note the hook you put on the coat hanger is on the bottom

 

tie the sash cord - i actually used a little more duct tape -  to the coat hanger hook and pull the coat hanger back up

 

and there you go - the end of the sash cord comes out the top - works (almost) every time - even better if you can remember where you left your coat hanger puller from last time. which i never do.
