From time to time, the cord may need to be changed due to wear and tear. With some time and effort, a homeowner can learn how to change a broken cord on a sash window by themselves. To make the repair, have a putty knife, small pry bar, flat head screw driver and several small nails on hand.
The first step will be to remove the interior stop. Use the putty knife to pry it open or unscrew it. Next, move the inner sash out the way carefully. The cords fit into stile grooves, which are vertical pieces inside the frame, and they are held in place with knots. Carefully pull these free and set the weights down. A good idea is to clean out this area of any dirt before reassembling it.
You have to pull of the parting strip next. They’re connected to the jambs, with are the upright supports in the frame. You might have to deal with nails when doing this, so be careful. You’ll have to move the upper sash out of your way before you can remove the cords.
The next step is to deal with the weight pockets. You can find them by taking off the weather stripping. They’re usually behind plates near the bottom of the jambs. If you don’t see them here, you may have to look behind the inner casing. Once these are out of the way, you can get to the weights.
Measure out the length of cord the window will need and cut them accordingly. Untie and remove the old ones and begin to feed the new ones into the assembly. Send them over the pulleys and down into the weight pockets. Loop them around a metal bar found in the weight before tying it. It can also be secured with wire.
Hold the weights in place by pulling them to the top of their pockets and putting a nail through them. Fasten it to the frame. Fasten the outer cords to their slots with screws. Next, replace the parting strip and take out the nails and the pulleys and then lift the sash. Tie the cords to the inner sash and then seal up the frame.
It’s recommended to go ahead and replace all the strings while you have it open, so that you don’t have to do this again for a while. You can opt to use chains instead of string if you want. In the long run, doing it yourself will be cheaper than having a professional do it.
