Then, wipe the tracks with a dry cloth and apply a silicone-based lubricant for more smooth glide. This lubricant is available at many home improvement stores or on the internet. You can test it by moving the sash upwards or downwards.

This causes cold air to seep around the window, making it difficult to heat your home.

Decay
If your sash windows have suffered from damage or decay the good news is that they aren't necessarily unfixable. The frames of these windows are typically made of high-quality timber.

The first thing to do is to strip any paint off the hardware. The bottom rail and the meeting rail could require removal from the frame (depending on the position of your sash). The next step is to take off the "pocket covers" which are bits of wood on the side of the frame lower down that provide access to the weights (the partsing beads run along the middle of them). You may require a sharp knife to remove them if they are fixed or painted. Once the pockets are removed you can begin to remove any wood rot, and then apply a high-quality, water-resistant wood filler. Once the wood filler has dried it is recommended that a primer coat be applied to stop further decay.
It is a smart idea to examine inside the window for weights of the sash to ensure that they are balanced. They should not be in the wrong alignment or pulled one side more than the other. The sash can slide off the track if it is not balanced. This could cause the frame to break or be damaged. You can replace the sashweights by new ones, or install an entirely new balance system to prevent the sash from swinging the wrong way.
