Sticking Sashes
If your double-hung windows get stuck and shatters, it's an absolute nightmare. They'll be difficult to see in the event that they shake during a storm.

Make use of a sharp knife, and put sheets of plastic and dust-collecting vacuum cleaners below the surface to collect any paint dust or chips.
Then, clean the tracks with a dry, clean cloth and apply a silicone lubricant to ensure more smooth sliding. You can find this in the majority of home improvement stores or on the internet. Then, move the sash upwards or down to test it.

Decay
If your sash windows have suffered from decay or damage, the good news is they aren't necessarily unfixable. The frames of these windows are usually constructed from high-quality timber. If you can restore them properly they can be repaired to ensure high performance for many years to come. The key is to conduct regular inspections and making sure that the wood is properly ventilated to stop the accumulation of moisture, which can cause wood to rot.

Although it is possible to repair damaged timber, the best way to avoid future decay is to keep the timber dry.
The first step is to remove any paint off the hardware. The bottom rail and meeting rail may have to be removed from the frame (depending on the location of your sash). The "pocket covers", which are small pieces of wood placed on the frame's sides that permit access to the weights, will need to be removed. They can be nailed in place and stuck with paint, so you will probably need to use an instrument to break them off. Once the pockets are removed you can begin to chisel out any wood rot, and then apply a high-quality, water-resistant wood filler. Once the filler has dried a coat of primer should be applied to guard against further decay.
It is an excellent idea to examine the sash's weights inside the window too to ensure that they are properly balanced and not swaying one side more than the other. The sash can fall off its track if they are not properly balanced. This could cause the frame to crack or be damaged. You can replace the sashweights using new ones, or put in an entirely new balance system to stop the sash from moving the wrong way.
Poor Security

It is essential to speak with a professional to assess the situation and determine if repairs to the window sash are needed.

A typical sash repair issue is when the sash becomes stuck in the frame. It could be caused by a snapped sash cord, or it could be a sign of a problem with the sash or ratchets. If it's the latter the gentle persuasion is usually enough to get the window open again - or alternatively, the ratchets will need to be reset.
Removal of the sash from the frame and cleaning the tracks of dirt or dust will often aid in resolving this problem. After cleaning the tracks, take off any security fittings and carefully remove the chains or cords that hold the sash. A draught seal may be placed around the staff bead in order to reduce the appearance of the paint finish. The gap between the box and the sash can then be filled with decorators caulk to improve the operation of the sash and lessen draughts.
