Sash Window Repair

Sash windows could be out of balance or even break. Pam is on the lookout on the internet for salvaged wavy glasses, and keeps an eye open for discarded metal sashweights. She then seeks replacements in the form of nuts or washers to ensure that her window is balanced.

Pam beds each pane with a rope of glazing compound that she puts into the rabbet groove or pocket, that is around the opening. This prevents drafts and costly heat loss.

Sashes that stick Sashes

If your double-hung window becomes stuck in the middle, it's a nightmare. They'll rattle during a storm, and you'll lose your view. On the other the other hand, windows that are too loose will allow external noise and air in and your energy costs can increase. Both of these scenarios are not ideal but they can be fixed with the appropriate tools and perseverance.

Paint can build up on the channels of old weighted window tracks, which can cause them to block. Luckily, most issues with this can be resolved by cleaning and lubricating the tracks.

Begin by removing the old caulking between the window stop (the internal one) and the window frame. Then scrape away any paint that has accumulated. Make sure to use a sharp blade, and then set up sheets of plastic and a vacuum cleaner right below to contain any paint dust and chips.

Clean the tracks with a dry cloth, and then apply a silicone-based lubricant that will help them slide better. You can find this at many home improvement stores or on the internet. Then, move the sash upwards or down to test it.

If it continues to stop it could be faulty. Verify whether the cord is tangled or hung in the sash, or if it's snapped. It is necessary to re-cord the window If this is the case.

A pin that keeps the rail in place might have been ripped out. It can be difficult to fix and you'll require the help of a professional most often.

If a pin hasn't fallen out but the wood has become swollen or warped it's a good idea to use a wood softener on it. The liquid is quick drying and can help restore damaged wood. You won't have to remove your sash windows to repair them. After you've used it, you can pull the two sashes apart by placing a piece wood in the bottom corner of the window where they meet.

Draughts

Draughts are a significant issue for windows with sash windows that are old particularly during winter months. Most often, they are caused by decayed timbers or cracked putty, worn weights for sash or sash cords that aren't balanced which can let cold air seep into the window, making it difficult to keep your home warm. There are a few ways to help prevent draughts in your windows that are sash, like filling any gaps with expanding foam or draught excluder strips that you can buy at most hardware stores.

It can be applied by itself or in conjunction with adhesive strips on the bottom and top of the frame. This is costly and you'll have to apply it again over the life of your window. But, it's a long-term fix and is simple to remove.

Cling film can also be used to block draughts. Simply roll it up and then push it into the gaps that surround your window. This is a great draught blocker, but the drawback is that it could block sash travel completely and could pose a fire hazard. The sash needs to be removed in order to reopen the window repairs, and the clingfilm will need reapplied every time the sash is closed.

As part of a complete refurbishment, you can have your sash window professionally draught-proofed. This could include the installation of new sash strings staff beads and parting beads as well as the lubrication and rebalancing of the weights and the lubrication and rebalancing the pulley wheel. It could also involve staining or painting of the frames and sashes. This can aid in restoring the function of the sash, and increase its energy efficiency, in addition to addressing any minor timber imperfections. It is less disruptive than taking out the windows and will reduce draughts, improve the thermal performance, and drastically reduce costs.

Decay

The good news is that your sash window frames are not in need of repair if they've been damaged or decayed. The frames of these windows are usually made of high-quality timber. If you can restore them properly they can be rehabilitated to ensure high performance for many years to come.

The first thing to do is to clean any paint from the hardware. The bottom rail and the meeting rail may have to be removed from the frame (depending on the position of your sash). The "pocket covers" are tiny pieces of wood on the frame's side that permit access to the weights, will need to be removed. You may require a sharp knife to take the pockets if they're fixed or painted. After the pockets have been removed, you can start slicing out any wood decay and apply an extremely high-quality, water-resistant filler. Once the filler is dry, a primer coat should be applied to stop further decay.

It is a good idea to examine inside the window for sashweights to make sure they are in balance. They should not be misaligned, or pulling one side more than the other. The sash can fall off its track if it is not balanced. This could cause the frame to crack or be damaged. The sash's weights can be replaced with new ones or a new balancing mechanism can be installed to stop the sashes from swinging to the wrong side of the frame.

Poor Security

Sash windows are prone to wear and tear from the weather over time. This can lead to the decay of timber, and will require replacement. Water marks on the window or a softened frame could be a sign of decaying wood. A professional consultation is needed to assess the situation and recommend any required sash window repair work.

In the same way, over time, the rails on the bottom can become damaged. Sills that have water marks, or a window that is soft to the touch could indicate this. A professional consultation will also be required to determine the situation and recommend any repair or replacement of window sash components.

It can be a real concern when double and triple glazing windows begin to let noise pollution back into the house. If this occurs the structural integrity of the window could be in danger and the sash window will require replacement.

If the latter is the case the gentle persuasion can usually help the window to be opened to reopen. Alternatively, the ratchets must be reset.

This issue can be solved by taking off the sash and cleaning the tracks. Once the tracks are clean, removing any security fittings that could be present, and then removing the sash cords and chains will allow the sash to be removed. The staff bead can be sealed with a draught-proof seal that will reduce the possibility of draughts. This can also improve the finish of paint. Decorators caulk can be used to fill the gap between the sash's sash box and the sash. This will improve the efficiency of the sash and reduce the risk of draughts.
