Weather strips are required on both sides of double-hung windows. It may be necessary to put strips within the frame at the bottom. The strips stop the window from snapping shut and also stop insects and dust from blowing through the gap between the sash and jamb.

Before installing the weather stripping, wash the sash frames with mild soap and water and dry them using a cloth. Remove any paint that is old and caulk around the inside stops with a utility knife.

If you're adding new ones, first take off the nail that binds each cord to the sash and remove the nails that secure each cord to the frame (the nails are referred to as glazier's points). If the pockets are in place on either side of the frame, you can remove them using a nail set or a Crowbar. It is likely that you will need to remove some of the old sash material.

Then, add a new balance for the sash (the tube that holds the weights), and you're done! (Don't forget to inspect and lock the tilt pin that is on the upper sash.)

Parting Beads

They help to retain the weights of sash repairing windows, prevent water ingress and create an enclosure between the inner and outer boxes. They can cause excessive draughts and rattle if they're damaged or in a poor state.

They are designed to be a snug fit but may have been secured with nails and you should check for nails or screws. You will also need to pull out any sash cords which were secured with screws and tied in knots to avoid them from falling off when released.

Once the parting beads are removed, it is possible to pull out the lower sash and then remove the meeting rail (which overlaps the bottom sash of the double glazing windows repairs hung sash) from both sides. The meeting rail can be removed of the frame, allowing you to view the window panes.

Finish just a few millimeters below the sightline. Replace the sash cords and tie knots if needed and re-hang the window. Consider using white 6mm braided marine rope / cord because it will last longer than cheap cords that stretch over time.
