The Biggest Problem With Sash Window Repair And How You Can Repair It

Sash Window Repair
Sash windows may become out of balance, or even break. Pam searches the internet for salvaged, wavy glass and is always looking for the sash weights that are discarded, made of metal. She then seeks replacements in the form of washers or nuts to ensure that her window is balanced.
Pam will set each pan by placing an edging rope into the rabbet groove, or pocket around the opening. This reduces drafts and reduce the cost of heat loss.
Sashes that stick Sashes
If your double-hung window becomes stuck and shatters, it's an absolute nightmare. You'll lose sight when they squeak in a storm. On the other side, a window that's too loose will allow external air and noise through and your energy costs can increase. Both of these scenarios aren't optimal however they can be fixed with the appropriate tools and persistence.
Paint can accumulate on the channels of old weighted window tracks, which can cause them to jam. The majority of these issues can be solved by cleaning and oiling the tracks.
Start by removing the caulking between the window stop (the internal one) and the window frame. Scrape off any paint that has been accumulating. Use window repairs and put sheets of plastic as well as an air-collecting vacuum cleaner beneath the surface to catch any paint dust or chips.
Then, wipe the tracks with a dry, clean cloth and apply a silicone lubricant for more smooth sliding. You can find this at most home improvement stores, or on the internet. You can test it by moving the sash either upwards or downwards.
If it is still jamming it could be an issue with the sash cord. Examine if the cord is caught or hanging in the sash, or if it's snapped. You'll need to re-cord your window if this is the situation.
A pin that keeps the rail in place may have been ripped out. It can be difficult to fix and you will have to call a professional the majority times.
If a pin hasn't fallen out, but the wood has become warped or swollen, it's recommended to use a wood softener on it. It's a quick drying liquid that can help to restore damaged wood, which means you'll be able to repair your window without having to take it off completely. After using it, you'll be able to pry the two sashes apart by placing a block of wood on the bottom corner where they meet, and tapping it lightly using the tool.
Draughts
Draughts can cause problems with sash windows that are old particularly in winter. They can be caused by decayed wood, cracked putty or worn cords for sash. This allows cold air to seep around the window, making it more difficult to warm your home. You can reduce the risk of drafts by filling in gaps with expanding foam or using draught-excluding strips available at most hardware shops. They are efficient however you'll require replacing them regularly as the foam expands over time with use.
Gapseal is a stronger solution that is more permanent. It's a spongy, rubbly seal that can be cut and then push into the gaps between the sash window frames. It can be applied by itself or in conjunction with adhesive strips on the bottom and top of the frame. This option is fairly expensive and will have to be applied over the course of your windows' lifespan, but it is a long-term solution and is easy to take off if you want to open the window.
Cling film can also be used to block drafts. Simply scrunch it up and then push it into the gaps surrounding your window. This is a great way to stop draughts however, it could also hinder the sash's movement and cause a fire. Additionally the sash needs to be removed to re-open the window and the cling film has to be reapplied each time you close the sash.
As part of a complete renovation it is possible to have your sash window professionally draught-proofed. This could include new sash cords as well as staff beads, parting beads, lubrication of pulley wheels and rebalancing the weights, in addition to staining or painting the frames and sashes. This can help to restore the sash's function and improve its energy efficiency, as well as dealing with any minor timber defects. It is much less disruptive than replacing windows entirely and can significantly reduce drafts and enhance the thermal efficiency of your home.
Decay
If your windows are sash and have suffered damage or decay the good news is that they are not necessarily beyond repair. The frames of these windows are generally made of high-quality timber. If you can restore them properly they can be repaired to provide high performance for a long time. The key is regular inspections and making sure that the wood is properly ventilated to avoid moisture build up which can cause wood to rot.
The majority of issues that arise with sash window are easily apparent, however some are more difficult to identify. Wood decay is particularly difficult to repair, since fungus eats the wood. It is possible to fix damaged sections of timber however the best way to prevent future decay is to ensure the wood is kept dry.
The first thing to do is to clean any paint off the hardware. The bottom rail and the connecting rail might need 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 sides that permit access to the weights, should be removed. You may require a sharp knife for removing them if they are fixed or painted. After the pockets have been removed, you can begin to chisel out any wood rot, and apply a good quality water-resistant wood filler. Once the filler is dry, the primer must be applied to prevent further decay.
It is recommended to inspect the sash weights within the window, too to ensure that they are in balance and not misaligned or pulling one side more than the other. If they're not balanced, the sash is liable to slide off its track and could cause damage to the frame. You can replace the sashweights by new ones or install an entirely new balance system to prevent the sash from moving the wrong way.
Poor Security
As time passes sash windows are exposed to the elements and prone to deterioration from weather and general wear. This can cause decay of the timber, which will require replacement. Water marks on the window or on a softened frame could be a sign of decaying wood. A professional consultation is required to determine the condition and recommend any needed repair work to the sash window.
In the same way, over time, the rails on the bottom can become damaged. This can be seen by the presence of water marks on the sill, or the window becoming soft. A professional will be needed to examine the situation and recommend any replacement of the sash window's seal or replacement.
Triple and double glazed Sash windows do an incredible job of keeping noise pollution out of your home, so it can be a real cause for concern when they start to let it back in. If this happens, the structural integrity of windows' sash could be at risk and it will most likely require to be replaced with an alternative option.
One common problem with repairing sash windows is the sash becoming stuck in the frame. This could be caused by an untidy cord or problems with sash ratchets. If the problem is related to the sash rats, a bit of gentle persuasion will usually work.
Removing the sash from the frame and removing the tracks of any dirt or dust will often assist in resolving this problem. After the tracks have been cleaned take off any security fittings that could be present, and then taking off the sash cords and chains will allow the sash be removed. A draught seal can then be applied around the staff bead in order to reduce draughts and enhance the appearance of the paint finish. Decorators caulk can be used to fill the gap between the sash's box and the sash. This will improve the efficiency of the sash and reduce the possibility of draughts.
