An alternative to replacing a drafty old double-hung window is to rebuild the window with a jamb liner kit made of aluminum replacement channels. The channels are a substitute for the worn wooden slots where the window sash slides up and down. When these get old and worn, they let cold air inside in the winter and cooled air escape in the summer.
Channels are sold in kits of various lengths at home centers, lumberyards and glass retailers. If you do it yourself, some carpentry experience is useful but not required. The project involves several steps: First you remove the inner and outer window sashes and the parting bead, which are pieces of wood trim that hold the sashes in place. Then you scrape the window frame so it's smooth, remove the weight cords and fill the cavity with scrap pieces of insulation. If the window needs painting, do it at this point while the frame is easy to work on. Then cut the channels to size and assemble the two sashes in them. The most difficult part of the job is holding the channels with the sashes between them while you position the unit in the frame and nail the channels into position. A helper will make this job easier. Then apply weatherstripping to the top, center and bottom of the windows.
