Installing new sash runner or spring bronze may be necessary if a gap prevents windows from closing and opening effortlessly. These bronze strips are stapled or nailed to the sash's lower edges to stop the rattling of the sides. They are available at DIY stores. Tubular vinyl weather-stripping is an alternative option, but it can tear and affect the appearance of a window.
It is essential to measure the entire window opening before installing replacement sash runner. It is best to take measurements from the top of the sash up to the horizontal centerline of the rail that connects them and from the bottom of sash down to the sill.

Repairing a sash window involves extensive dismantling of the frame of the window, so it's best left to professionals. With the right tools and skills, it is possible to fix an the sash window that is old. Adam shows Jess the basics:
Remove any security fittings that are behind the lower window sash. Then, take off the staff bead. Then, remove the bottom sash. Take the chains and cords from both sides, and knot them in such a way that they won't be pulled back by the weights attached. It's now time to remove the upper sash. The sash stops must be removed, a thin vertical wood strip that holds the sash. Also, take off any painted-covered hardware. The sash can be pulled back to reveal the weight balancing, which is a large iron cylinder that is encased inside a hidden compartment and anchored by rope. To keep the sash from falling into the void make a hole in it using nails and remove the weight.
Once the sashes are free, clean out the jamb and rails that meet, remove the glazing bars and sash cords, and scrape off any paint off the sash stops with an utility knife. Reattach the stops once the sashes have been reinstalled. Use nails that are small enough not to puncture the balancing weight.
To reassemble the sash place the top sash onto its track first, then the lower sash. Make sure that the sash stops and the frame are aligned properly. If necessary, reattach any beads used for parting. Then, reconnect the sash cords or chains and re-install the sash pulley axles.
