It's less disruptive than removing the windows, and can reduce draughts, improve the thermal efficiency and dramatically reduce costs.

Decay

The good news is that sash window frames are not beyond repair if they have been damaged or decayed. The frames of these windows are generally made of high-quality timber.

You will then need to remove the "pocket covers" which are bits of wood that are located on the sides of the frame lower down that provide access to the weights (the parting beads run through the middle of them). They can be fixed by nailing them in place and then securing them with paint, so you will probably need to use an instrument to break them out of the way. Once the pockets are gone, you can begin to chisel out any wood that is rotting, and then apply a high-quality water-resistant wood filler. Once the filler is dry, it is recommended that a coat of primer be applied to guard against further decay.

It is a good idea to check the sash weights within the window, too to ensure that they are in balance and not swaying one side more than the other. The sash can slide off the track if it is not properly balanced. This could cause the frame to crack or even be damaged. You can replace the sashweights by new ones or install an updated balancing system to stop the sash from swinging the wrong direction.
