It is crucial to measure the entire window opening prior to installing a new sash runners. It is best to take measurements from the top of the sash to the horizontal line of the rail that connects it and from the bottom of the sash down to the sill.

A full refurbishment can also include adding draught proofing, re-attaching the sash furniture/ironmongery and replacing the parting bead (the dividing strip between the two panes of glass).

To start a repair project take out the window stops (the moldings in front of the lower sash). Next, loosen the staff bead and take off the lower sash. Take the chains and cords from both sides. Lastly remove the sashweights from the bottom weight cavity. Store the hardware in a safe location. Use a heat gun to soften hardened filler or putty. Scrape it away with a blade made of putty.

Remove any security fittings behind the lower window sash. Then, remove the staff bead. Then, remove the sash at the bottom. Remove the cords and chains from both sides, and tie them in a way that they can't be pulled back by the attached weights. It's now time to take out the upper sash. Unscrew the sash stoppers (a thin vertical strip of wood that is used to hold the sash) and then loosen any painted-covered hardware. Unscrew the sash to reveal the balancing weight, which is a heavy iron cylinder that is encased inside a hidden compartment and secured by a rope. To prevent the sash falling into the void, pierce it with a nail and then sacrifice the weight.

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

To reassemble the sash place the top sash on its track first, and then the lower sash. Check that the sash stops and the frame are properly aligned. If necessary, reattach any parting beads. Then, reconnect the sash cords or chains and re-attach the axles of the sash pulleys.
