The gaps between sash and frame are the main source of draughts. They can also trigger rattling and reduced sound-proofing. Different methods can be employed to stop air leaks from windows with sash, including sealing beads, specialty products and secondary glazing.

A gap between the top and bottom of the sash and the jamb frame, is a common problem. This can cause moisture to leak in, rotting wood and the growth of mold. Seal the gap with silicone, polyurethane, or foam sealant.

If a gap is preventing windows from opening and closing smoothly, it may be necessary to install new sash runners or spring bronze.

To begin the repair, remove the window stops. (The moldings are located in front of the lower glass). Next, loosen the staff bead, then remove the lower sash. Take off the chains or cords on both sides. Then, remove the sashweights from the bottom weight cavity. Store the hardware in a safe location. Soften any old filler, hardened putty, or filler using a heat gun, and scrape it off with the help of a putty knife. Reassemble the window, reconnect the hardware and lubricate the pulley axles with silicone or Teflon spray. Install the parting beads again and reinstall the upper part of the sash.

Remove the sash stops which is a thin vertical strip of wood that is used to hold the sash. Also, take off any hardware that has been painted. Pull the sash back to reveal the weight. It is a massive iron or lead cylinder that is hidden in a cavity, and secured by cords. To prevent the sash from falling into the void, make a hole in it using a nail and sacrifice the weight.

After the sashes have been removed, clean the jambs and the rails that meet. Remove the glazing bars and the cords for the sash. Then, using a utility blade take off any paint from the sash stop. Reattach the stops after the sashes are reinstalled. Use nails that are small enough not to puncture the balancing weight.
