Begin by removing the old caulking between the window stop (the interior one) and the window frame. Scrape away any paint that has accumulated. Use a sharp knife and place plastic sheets and an air-collecting vacuum cleaner beneath the surface to collect any paint dust or chips.

Clean the tracks using a dry cloth, and apply a silicone-based lubricant that will aid in their smoother movement. The lubricant can be found at most home improvement shops or on the internet. You can test it by moving the sash upwards or downwards.

If it still jams, there could be a problem with the sash cord. Verify if the cord is catching or hanging in the sash, or if it has snapped completely. If this is the case, you'll have to re-cord the window.

However, it's an effective long-term fix and simple to remove.

It may also include painting or staining of the frames and the sashes. This can restore the sash to its original function and increase its energy efficiency, and repair any minor defects in the timber. It's less disruptive than taking out the windows and will reduce drafts, enhance thermal performance and significantly reduce costs.

Decay

The "pocket covers" are tiny pieces of wood placed on the frame's side, which allow access to the weights, should be removed. These are often put in place by nails and then covered with paint, so you'll probably need to use an instrument to break them off. Once the pockets have been removed, you can start slicing out any wood decay and apply an extremely high-quality water-resistant filler. Once the filler has dried it is recommended that a coat of primer be applied to protect against further decay.

It is a good idea to check the sash weights within the window too, to ensure that they are properly balanced and not pulling one side more than the other. The sash may be thrown off its track if they are not properly balanced. This could cause the frame to fall or be damaged. The sash weights could be replaced with new ones or a new mechanism for balancing can be fitted to stop the sashes from swinging towards the wrong side of the frame.
