Scrape off any paint that has accumulated. Use a sharp knife and put sheets of plastic and an air-collecting vacuum cleaner beneath the surface to catch any paint dust or chips. Clean the tracks with a dry cloth, then apply an oil based on silicone to help them slide better. You can find this in many home improvement stores or on the internet. You can test it by moving the sash upwards or downwards. If it continues to jam it could be faulty. Examine whether the cord is stuck or hanging from the sash or snapped.

This allows cold air to seep around the window, making it more difficult to heat your home. You can prevent draughts by filling gaps with expanding foam, or by using draught-proof strips that are found in many hardware stores.

It may be necessary to remove the bottom rail from the frame and also the rail that joins it (this will depend on the position of the sash). The pocket covers are tiny pieces of wood on the frame's sides that allow access to the weights, will need to be removed. They can be put in place by nails and then covered with paint, so you will probably need to use an instrument to break them out of the way. After the pockets have been removed, you can start cutting out any wood rot and apply an excellent water-resistant filler. Once the filler has dried, a primer coat should be applied to stop further decay. It is recommended to inspect the sash weights within the window as well to make sure they are balanced and not pulling one side more than the other. If they aren't balanced, the sash can fall off its track and could break or damage the frame. You can replace the sashweights using new ones, or install an updated balancing system to stop the sash from swinging in the wrong direction.

If the issue is with the sash's the ratchets, some gentle pressure is usually enough. Removal of the sash from the frame and removing the tracks of dust or dirt can often aid in resolving this issue. Once the tracks are clean, removing any security fittings that might be present. Lastly, carefully removing the sash cords and chains will allow the sash to be removed.
