Sash Cords that are damaged or Worn
Over time, sash cables may become brittle and snap or break. This can be the result of a window problem, like a damaged pulley, or it could occur when the sash has been closed and opened repeatedly. When this occurs the sash is likely to be difficult to move up and down without sticking or requiring a lot of effort.
To fix damaged sash cords, first open the window and locate the parting beads, a thin piece of wood that separates the upper and lower sashes. Remove the bead gently from the frame using the screwdriver. After removing the bead you can now begin to remove the sash. When the sash is removed, you will need to find the two cast iron weights that are housed in a pocket on the opposite side of the sash. The majority of the time, one weight is located in the back (towards exterior side of window frame) and another in front (towards the inside of the frame). Remove both weights from their pockets and put them aside.
After you have removed the counterweights, remove the access panel from the sash channel. Depending on the kind of window you have, there could be screws or a chisel to assist you in removing the panel. When the panel is removed, you'll be able to see the coiled spring that helps retract the sash cords. If this isn't functioning properly, you might be able to hear windows trying to move, and feel a little resistance.
To fix this fix, you'll need re-coil the spring. Once it's re-coil, you can secure it in place with the help of a cord. It is important to do this properly since a loose knot can result in the cords breaking and not retracting when you need them.
After the cords have been re-tied and the access panels as well as the jambliner. Slide the sash into place. Double-check that the new cords are long enough and secure. After this, you can put the sash cords back into the slots and holes on the sides of the lower sash and put the counterweights back into their pockets. Now you can test your work. Move the sash up and down to ensure it moves smoothly.
Air leaks and drafts
Sash windows can develop drafts and air leaks as a result of age or damage to the window or even just poor construction. Although these problems are typically a sign of windows that are ready to be replaced, they are also repairable or repaired with a bit of effort.
Weather stripping that has worn out or is missing could create drafts and air leaks. Foam tape or similar products is a good choice to seal the gaps between the sash frame. This helps to seal the gap and keeps cold or hot air out. If the weather stripping is damaged or folded over, or is missing, it can cause drafts and energy inefficiency.

Rotting Wood
As wood rots, it loses the ability to hold nails or other fasteners. This loss of structural integrity can eventually lead to window damage or even total collapse. Repairing wood windows that are rotting is a viable solution, but replacing them is usually a better solution. To avoid rotting, examine your windows on a regular basis for evidence of moisture buildup. Then, take steps to correct any issues you find.
In the course of routine maintenance, you must clean your windows to get rid of the dirt and grime that may stop the movement of sashes. Additionally, you should use a dehumidifier to control humidity levels, as excessive moisture can cause wood to expand and stick. It is also possible to apply a thin layer of wax on window tracks and sashes, in order to help lubricate them.
If a sash becomes stuck, the first step is to examine the counterweights for any imbalance. If the counterweights appear be in good condition, and there are no signs of imbalance, it's possible that the issue is due to an draft or air leak.

The earliest sashes were joined with wooden pegs connected by a mortise-and tenon. This kind of joint is a bit more complicated to disassemble and will require the use of a handsaw, a knife, or a hammer to cut through the glue line. Later sashes made use of glue, that is much easier to separate.
Once the sash has been repaired, it's time to insert the vinyl track into the frame. Release the pawls on each locking terminal using an screwdriver, then lower the sash so that it is seated in the vinyl jamb liners.
