Weather stripping is a thin flexible strip of fabric used to seal the edges of windows and doors when they are closed. It blocks out outside air as well as the harmful substances it holds. It keeps drafts from blowing through the gaps, making your home too cold or letting noise from outside in. You can buy ready-to-use materials in a variety of sizes, or cut it to fit window sashes.

Weather strips are required on both sides of double-hung windows. You may need to add strips inside the frame near the bottom. The strips stop the window from closing, and they also stop insects and dust from blowing through the space between the jamb and the sash.

Sash Cords

If you are replacing them, remove the nail holding each cord to the sash. Then pull out the nails that secure each cord to the sash. Then, if the pockets on either side of the frame are still in place, pull them out using a hammer and nail set or an Crowbar. It is likely that you will need to remove some of the old sash material.
You can remove the sash's outer layer once the pockets are opened. Then you'll be able see the channels where the cords of sash pass on both sides.

You'll need to ensure that you have the correct amount of weight per sash. You can weigh them with an ordinary kitchen scale to be certain but the weights must be about half the size of the sash.
If the tilt pin on the bottom of the lower sash still in place, reset it. You'll need to lift your sash up slightly to do this, so take care not to let it fall. Then, lock the pin. Then, add the new sash balance (the tube that holds the weights) then you're done! Be sure to examine the tilt pin and relock it on the upper sash.

If they're damaged or in poor condition it can lead to excessive rattle and draughts.

Look for screws or nails prior to gently prying the parting beads from their narrow grooves. They are designed to fit snugly however they could have been secured with nails. Also, you'll need to pull out any sash cords which were secured with screws and tied in knots to stop them dropping when released.
Once the parting bead is removed, it is possible to take the lower sash out and then remove the meeting rail (which is affixed to the bottom sash of a double hung sash) from both sides. The meeting rail can be removed of the frame, allowing you to see the windows.
