Remove the caulking that was used in the space between the window stop (the one on the inside) and the frame of the window. Then scrape away any paint that has accumulated. Make sure to make use of a sharp blade and set up sheets of plastic and a vacuum cleaner directly below to catch any paint dust and chips.
Then, clean the tracks with a dry, clean cloth and apply a silicone lubricant to ensure more smooth gliding. This lubricant is available at many home improvement stores or on the internet. You can test it by moving the sash either upwards or downwards.
If it still jams it could be a problem with the sash cord. Verify whether the cord is tangled or hanging in the sash, or if it's snapped. If this is the case, you'll need to replace the window's cord.

Draughts
Draughts can cause problems when you have an old sash window particularly in winter. Most often, they are caused by decayed timbers or cracked putty, worn weights, or sash cords that are not balanced which can allow cold air to get in around the window, making it difficult to keep your home warm. There are several options you can take to help prevent draughts in your windows with sash, for example, filling any gaps with foam that expands or draught excluder strips that you can buy at most hardware stores. They're effective, but they will require replacing them regularly because the foam expands with use.
A alternative that is more durable is Gapseal, a rubbery spongy seal that you can cut to size and insert into the gaps between the window frames of your sash. It can be applied by itself or with adhesive strips on the bottom and top of the frame. This is costly and you will need to reapply it throughout the life of your window. However, it is a long-term fix and is easy to remove.
Another popular DIY method of draughtproofing is to use cling wrap that is rolled up and put into every gap around your window. This is a good draught-stopper, but it can also hinder the movement of the sash and cause a fire. In addition, the sash will need to be removed for you to re-open the door and the cling film will need to be reapplied each time you close the sash.
As part of a general refurbishment, you can have your window draught-proofed. This could include new sash cords and parting beads, staff beads, lubrication of pulley wheels and rebalancing of the weights, and painting or staining the frames and sashes. This will help restore the function of the sash, and increase its energy efficiency, as well as addressing any minor timber defects. It is less disruptive than removing the windows, and can reduce draughts, increase the thermal efficiency and dramatically reduce the cost.
Decay
The good news is that sash window frames are not beyond repair if they have been damaged or degraded. The frames of these windows are generally constructed of high-quality wood. With the right restoration, they can be restored to give you the best performance for many years to come. The key is regularly checking the frames and ensuring that the wood is well ventilated to prevent moisture accumulation, which can cause wood rot.
The majority of the issues you'll encounter with sash windows are readily apparent on close visual inspection, but some are more difficult to detect. Wood decay is a challenge to fix, as the fungus consumes the wood. It is possible to repair rotten sections of timber, however the best way to prevent future decay is to ensure the wood is kept dry.
First, clean any paint from the hardware. It may be necessary to remove the bottom rail from the frame and the rail for meeting (this will depend on the location of the sash). The next step is to take off the "pocket covers" which are pieces of wood in the side of the frame that are low down that give access to the weights (the partsing beads run along the middle of them). These can sometimes be fixed by nailing them in place and then securing them with paint, so you'll likely require a knife to get them loose. Once the pockets have been removed, you can begin cutting out any wood rot and apply a high-quality, water-resistant filler. Once the filler has dried it is recommended that a primer coat be applied to prevent further decay.
It is a good idea to check inside the window the weights of the sash to ensure that they are in balance. They should not be displaced, or pulling one side harder than the other. The sash can be thrown off its track if they are not balanced. This could cause the frame to break or be damaged. You can replace the sashweights using new ones, or put in an entirely new balance system to stop the sash from swinging in the wrong way.
Poor Security
As time passes sash windows are exposed to the elements, and are prone to damage from weather and general wear. Over time, this can lead to timber decay which is then required to be replaced, a costly repair that needs to be addressed as quickly as possible. Wood decay can be spotted by water marks on the window, or the frame turning soft to the touch. It is essential to speak with a professional to assess the situation and determine if any repairs to the sash window are required.
Similarly, over time the rails at the bottom may become damaged. Water marks on the sill, or a window that is soft to the touch may be a sign of this. A professional consultation will be required to evaluate the situation and recommend any needed resealing or replacement of window sash components.
Triple and double glazed sash windows do an amazing job at keeping noise out of the home, and it could be a major cause of worry when they begin to let it in. If this happens, the structural integrity may be in danger and the sash window may have to be replaced.

If the latter is the case scenario, a little gentle pressure can help the window to be opened again - or alternatively, the ratchets will need to be reset.

After the tracks have been cleaned take off any security fittings that might be present and then carefully taking off the sash cords and chains will allow the sash to be removed. The staff bead may be sealed with a draught-proof seal that will reduce draughts. This will also improve the finish of paint.
