Sash Window Repair
Sash windows may become out of balance or even break. Pam browses the internet for wavy glasses that are salvaged and keeps an eye open for discarded sashweights made of metal. She then seeks replacements, like nuts or washers, to ensure that her window is balanced.
Pam will set each pane by placing a rope of glazing material into the rabbet groove, or pocket around the opening. This prevents drafts and costly heat loss.
Sticking Sashes
When your double-hung window gets stuck and shatters, it's a nightmare. You'll lose your view if they rattle during a storm. A window that is too loose can let in external noise and air which can increase your energy costs. Both scenarios are not optimal but they can be fixed with the proper tools and persistence.
One of the most common issues with windows that are weighted is that paint could build up in the channels that they slide on, making them jam. Most of these problems can be solved by cleaning and oiling the tracks.
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 accumulated paint. Be sure to use a sharp blade, and set up sheets of plastic and a vacuum cleaner right below to keep any paint dust and chips.
Then, wipe the tracks using a dry cloth, and apply a silicone lubricant to ensure better sliding. 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.

These can be efficient, but they'll need to be replaced from time to time as the foam expands and gets worn away with time.
A more permanent solution is Gapseal, which is a sponge-like seal that you can cut to size and put into the gaps between your sash window frame.

However, it's an effective long-term fix and simple to remove.
Cling film can also be used to block drafts. Simply roll it up and then push it into all the gaps surrounding your window. This is an effective draught blocker, but the drawback is that it could stop sash movement completely and pose an hazard to fire. The sash must be removed in order to reopen the window, and the clingfilm needs to be reapplied every time the sash is closed.

The "pocket covers" are tiny pieces of wood placed on the frame's side, which allow access to the weights, should be removed. These can sometimes be nailed in place and stuck with paint, so you will probably need to use a knife to get them off. 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 filler is dry, it is recommended that a coat of primer be applied to protect against further decay.
It is a good idea to check the sash's weights inside the window too, to ensure that they are balanced and not pulling one side more than the other. The sash can be thrown off its track if they aren't properly balanced. This could cause the frame to crack or become damaged. The sash's weights can be replaced with new ones or a new balancing mechanism could be fitted, which will stop the sashes from swinging to the wrong side of the window frame.
