Sashes that stick Sashes

If your double-hung windows get stuck, it's an absolute nightmare. You'll lose your view in the event that they shake during a storm. On the other side, a window that's too loose will let external air and noise in and your energy costs can increase. This is neither ideal, but both can be fixed with the proper tools and determination.

Paint can accumulate on the channels of old weighted sash window tracks, which can cause them to block. Most of these problems can be resolved by cleaning and oiling the tracks.

Begin by removing the old caulking between the window stop (the one inside) and the window frame. Then scrape away any accumulated paint. Make sure to use a sharp blade, and then put up plastic sheets and a vacuum cleaner directly below to keep any paint dust and chips.

Then, wipe the tracks with a dry cloth and apply a silicone lubricant for better sliding. The lubricant can be found at many home improvement stores or on the internet. You can test it by dragging the sash upwards or downwards.

If it still jams it could be due to an issue with the sash cord. Verify if the cord is caught or hanging from the sash or snapped. If this is the case, you'll have to replace the window's cord.

A pin that keeps the rail in place might have lost its grip. It can be difficult to fix and you will need to call in an expert most often.

Often caused by rotten timbers, cracked putty, worn sash cords or unbalanced weights that let cold air seep into the window and make it difficult to keep your home warm. There are several ways to prevent draughts from entering your sash windows, such as filling any gaps with foam that expands or strips to block draughts that you can purchase at many hardware stores. These are effective, although they'll have to be replaced periodically as the foam expands and wears away with time.

A more permanent solution is Gapseal, a rubbery spongy seal that you cut to size and put into the gaps between the window frames of your sash. It can be used on its own or with adhesive strips placed on the top and bottom of the frame. This is costly and you'll need to apply it again throughout the life of your window. However, it's an affordable fix that is easy to remove.

Cling film can also be used to stop drafts. Simply scrunch it and then push it into all the gaps around your window. This is an effective draught stopper but the downside is that it can stop sash movement completely and pose an hazard to fire. Furthermore the sash will have to be removed for you to open the window again and the cling film has to be applied every time you close the sash.

An alternative that is less expensive is to have your sash windows professionally draught proofed as part of a complete refurbishment service. This could include the installation of new sash strings parting beads and staff beads, the lubrication and rebalancing the weights, as well as the oiling and rebalancing of the pulley wheel. It may also involve staining or painting of the frames and sashes. This can bring the sash back to its original purpose, improve its energy efficiency and correct any minor flaws in the timber. It's much less disruptive than replacing windows completely and will dramatically reduce draughts and improve your home's thermal performance.

Decay

The good news is that windows' sash frames aren't in need of repair if they've been damaged or decayed. The frames of these windows are usually constructed of high-quality wood.

The "pocket covers" are tiny pieces of wood that are placed on the frame's side, which permit access to the weights, should be removed. You may need to use a sharp knife to take them if they're fixed or painted. Once the pockets have been removed, you can start chiseling out any wood rot and apply a high-quality, water-resistant filler. After the filler has dried, a coat of primer should be applied to protect against further decay.


It is recommended to inspect the sash weights inside the window as well to make sure they are properly balanced and not swaying one side more than the other. The sash can be thrown off its track if it is not balanced. This could cause the frame to break or even be damaged. You can replace the sashweights by new ones or install a new balancing system to prevent the sash from swinging in the wrong way.
