Sashes that stick Sashes
It's a nightmare when your double-hung windows become stuck. They'll sway during an icy storm and you'll lose your view. On the other the other hand, windows that are too loose will allow external noise and air in and your energy costs may increase. Neither scenario is ideal, but both can be fixed with the proper tools and determination.
A common problem with old windows with weighted sash is that paint could accumulate in the channels that they slide on, making them jam. Luckily, most issues with this can be solved by cleaning and lubricating the tracks.
Take the caulking off of the space between the window stop (the one on the inside) and the frame of the window. Scrape off any paint that has accumulated. Make use of a sharp knife and put 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, then apply an oil based on silicone to help them slide better. You can purchase this in the majority of home improvement stores or online. You can test it by moving the sash either upwards or downwards.
If it continues to jam it could be due to 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 have to reconnect the window.
A pin that keeps the rail in place could have been ripped out. It isn't easy to fix and you will have to call a professional the majority often.
If a pin doesn't fall out but the wood has become swollen or warped, it's a good idea apply a wood hardener to it. This liquid will dry quickly and can restore damaged wood. You won't have to take out your sash windows in order to repair them. After using it, you can pull apart the two sashes by placing a piece wood on the lower corner of the window where they meet.
Draughts
Draughts can be a concern with sash windows that are old particularly in the winter. Most often, they are caused by decayed timbers or cracked putty, worn weights for sash or sash cords that aren't balanced, they can allow cold air to seep into the window, making it difficult to keep your home warm. There are several options you can take to stop draughts from coming through your sash windows, such as filling any gaps with expanding foam or strips to prevent draughts. These can purchase from most hardware stores. These are effective however, you will require replacement periodically as the foam expands over time with usage.
A alternative that is more durable is Gapseal which is a sponge-like seal that you cut to size and push into the gaps between your sash window frame. It can be used on its own or with adhesive strips at the top and bottom. This option is quite costly and will have to be applied over the time of your windows' life, but it can provide a long-term solution and is easy to remove if you want to open the window.
Cling film can also be used to block draughts. Simply scrunch it up and then push it into the gaps surrounding your window. This is a good draught-stopper, but it can also block the sash's movement and even cause a fire. Additionally the sash will have to be removed for you to open the window again and the cling film needs to be reapplied each time you close the sash.
As part of a complete refurbishment, you can have your window draught-proofed. This can include new sash cords as well as staff beads, parting beads, lubrication of pulley wheels, and rebalancing the weights, in addition to painting or staining the frames and sashes. This will bring the sash back to its original purpose and increase its energy efficiency and correct any minor defects in the wood. It is much less disruptive than replacing the windows altogether and will significantly reduce drafts and enhance the thermal efficiency of your home.
Decay
The good thing is that your windows' sash frames aren't in need of repair if they've been damaged or deteriorated. The frames of these windows are typically made of high-quality timber. With the right restoration, they can be restored to ensure high performance for many years to come. The key is regular inspections and ensuring that the wood is well ventilated to prevent moisture accumulation, which can cause wood rot.
Most of the problems you will face with sash windows are readily apparent on close visual inspection, but some are harder to spot. Wood decay is difficult to fix, as fungus can eat the wood. It is possible to repair rotten sections of timber, however, the best method to avoid further decay is to ensure the timber is dry.
The first thing to do is to remove any paint from the hardware. It may be necessary to remove the bottom rail from the frame, and also the meeting rail (this will depend on the location of the sash). The "pocket covers" are tiny pieces of wood that are placed on the frame's side, which permit access to the weights, will need to be removed. These are often nailed in place and stuck with paint, so you will probably need to use an instrument to break them loose. Once the pockets are removed you can begin to chisel out any wood rot and apply a good quality water-resistant wood filler. Once the filler is dry, a coat of primer should be applied to prevent further decay.
It is an excellent idea to examine the sash weights within the window as well, to ensure that they are balanced and not misaligned or pulling one side more than the other. If they are not balanced the sash can fall off its track and cause damage to the frame. You can replace the sashweights using new ones, or install an entirely new balance system to stop the sash from swinging the wrong way.
Poor Security
Sash windows are prone to wear and tear due to weather conditions over time. In time, this may cause wood decay, which in turn will need to be replaced, a costly repair that needs to be addressed as quickly as is possible. The signs of decaying wood can be seen by water marks under the window or by the frame becoming soft to touch. A professional consultation will be needed to assess the situation and recommend any required repairs to the sash window.
Additionally, with 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 an indication of this. A professional consultation may be required to determine the situation and recommend any replacement or resealing of the sash window's components.

One common window repair issue for sash windows is that the sash becomes stuck in the frame. It could be caused by the sash cord being snapped or it could be an indication of an issue with the sash ratchets. If it's the latter scenario, a little gentle persuasion can usually help the window to be opened and then the ratchets need to be reset.
This issue can be solved by taking the sash off and cleaning the tracks. After the tracks have been cleaned take off any security fittings that might be present. Lastly, carefully removing the sash cords and chains will allow the sash be removed. A draught seal may be put on the staff bead to reduce the appearance of the paint finish. Decorators caulk can be used to fill the gap between the sash's box and the sash. This will improve the sash's operation and also reduce the risk of draughts.
