Tubular vinyl weather-stripping is an alternative option, but it can tear and make a difference to the appearance of windows.

When installing replacement sash runners it is essential to take full measurements of the window opening. It is best to measure from the top of the sash to the horizontal line of the rail that connects it, and from the bottom of the sash to the sill. These measurements can be transferred to new runners which will ensure a better fit and operation of the window.

Remove the sash stops (a thin vertical strip of wood that supports the sash) and then loosen any paint-encrusted hardware. Pull the sash back to reveal the weight. It is a heavy iron or lead cylinder that is hidden in a cavity and is supported by cords. To stop the sash from falling into the void pierce it using a nail, and sacrifice the weight.
