Then, clean the tracks with a dry cloth and apply a silicone lubricant for better gliding. It is available in many home improvement stores or online.

Decay The good thing is that your frames for sash windows aren't in need of repair if they've been damaged or deteriorated.

It is possible to remove the bottom rail from the frame and also the rail that joins it (this will depend on the location of the sash). The “pocket covers” are tiny pieces of wood that are placed on the frame's sides that allow access to the weights must be removed. It is possible to use a sharp knife to remove them if they are attached by nails or paint. Once the pockets are removed you can begin to chisel away any wood rot and then apply a high-quality, water-resistant wood filler. Once the filler has dried the primer coat must be applied to stop further decay. It is recommended to inspect the sash weights within the window, too, to ensure that they are balanced and not swaying one side more than the other. If they are not balanced the sash could slide off its track and cause damage to the frame. The sash weights could be replaced with new ones or a new balance mechanism can be fitted to stop the sashes from swinging towards the opposite side of the window frame. Poor Security Sash windows are susceptible to damage and wear due to weather conditions over time. As time passes, this could result in wood decay that requires to be replaced – a costly repair that needs to be dealt with as soon as is possible.

Alternatively, the ratchets will need to be reset. This issue can be fixed by taking the sash off and cleaning the tracks. After the tracks have been cleaned, removing any security fittings that could be present, and then removal of the sash cords as well as chains will allow the sash to be removed. A draught seal can then be put on the staff bead to reduce draughts and improve the appearance of the paint finish.
