Sash Window Repair

Sash windows can go out of balance and crack. Pam scours the web for window repairs salvaged waving glass, wavy and keeps an eye out for the sash weights that are discarded, made of metal. She then searches for replacements, such as nuts or washers, to balance her window.

Pam beds each pane with a rope of glazing compound that she uses to create the rabbet groove, also known as a pocket, that is around the opening. This reduces drafts and reduce the cost of heat loss.

Sashes that stick Sashes

It's a nightmare when your double-hung windows become stuck. They'll shake in the event of a storm, and you'll lose your view. A window that is too loose can let in external noise and air which could increase your energy bills. Neither scenario is optimal, but both can be addressed with the proper tools and determination.

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

Begin by removing the caulking between the window stop (the internal one) and the window frame. Then scrape off any paint that has accumulated. Make use of a sharp knife and place plastic sheets and a dust-collecting vacuum cleaner below the surface to collect any paint dust or chips.

Clean the tracks using a dry cloth, and then apply a silicone-based lubricant to make them more gliding. The lubricant can be found at most home improvement shops or online. You can test it by dragging the sash upwards or downwards.

If it continues to jam it could be due to a problem with the sash cord. Check to see if the cord is caught or hanging from the sash, or if it's snapped. You'll need to re-cord your window If this is the case.

Another possible reason for the jam could be the pin that holds the rail in place has slipped away. This can be tricky to fix, and you'll need to contact an expert in most instances.

If a pin doesn't fall out but the wood has become swollen or warped, it's recommended to apply a wood hardener to it. It's a fast drying liquid that can help to restore damaged wood, and you'll be able to fix your window without needing to remove it completely. Once you've used it, you'll be able to pry the two sashes apart by placing a piece of wood on the top of the corner where they meet, and tapping it lightly with an Hammer.

Draughts

Draughts are a major problem for windows with sash windows that are old particularly during winter months. They can be caused by decayed wood, broken putty or worn cords for sash. This causes cold air to seep around the window, making it difficult to heat your home. There are several things you can do to prevent draughts from entering your sash windows, such as filling any gaps with expanding foam or using strips to block draughts that you can purchase at many hardware stores. These are effective, although they'll need to be replaced regularly as the foam expands and gets worn away with wear and use.

Gapseal is a longer-lasting solution. It's a spongy, rubbbery seal you can cut and then push into the gaps between the sash window frames. It can be used on its own or with adhesive strips on the bottom and top of the frame. This is a bit costly and must be applied over the time of your windows' lifespan, but it is an option for the long term and is easy to take off when you wish to open the window.

Cling film can also be used to stop drafts. Simply roll it up and push it into all the gaps surrounding your window. This is a reliable draught stopper, but the drawback is that it could hinder sash movement completely and pose an hazard to fire. Additionally the sash needs to be removed to open the window again and the cling film has to be applied each time you close the sash.

As part of a comprehensive renovation you can have your window draught-proofed professionally. This could include new sash cords and parting beads, staff beads, lubrication of pulley wheels, and rebalancing the weights, and staining or painting the frames and sashes. This will help restore the function of the sash and increase its energy efficiency, as well as fixing any minor wood imperfections. It is much less disruptive than replacing the windows altogether and will significantly reduce draughts and improve your home's thermal efficiency.

Decay

If your sash windows have suffered from decay or damage, the good news is that they are not necessarily beyond repair. The timber used to construct the frames of these windows is generally of high-quality and with proper restoration they can be revived to provide an excellent level of performance for many years. The key is to conduct regular inspections and making sure that the wood is properly ventilated to stop moisture build up, which can cause wood to rot.

The majority of problems that arise from sash windows are readily apparent, however some are more difficult to detect. Wood decay is particularly difficult to treat, since fungus eats the wood. Although it is possible to repair rotten timber, the best way to prevent further rot is by keeping the timber dry.

First, remove any paint from the hardware. It could be necessary to remove the bottom rail from the frame, and also the rail that joins it (this will depend on the position of the sash). You'll then have to remove the "pocket covers" which are pieces of wood that are located on the sides of the frame that are low down that allow access to the weights (the partsing beads run along the middle of them). These can sometimes be nailed in place and stuck with paint, so you'll likely need to use a knife to cut them out of the way. Once the pockets are gone, you can begin to remove any wood rot, and apply a good quality water-resistant wood filler. Once the filler has dried, a primer coat should be applied to prevent further decay.

It is recommended to inspect the sash weights within the window too, to ensure that they are balanced and not misaligned or pulling one side more than the other. If they're not balanced, the sash could drop off its track and could cause damage to the frame. The sash weights can be replaced with new ones or a new mechanism for balancing could be fitted, which will stop the sashes from bouncing to the wrong side of the frame.

Poor Security

Sash windows repair are susceptible to damage and wear due to weather conditions over time. This can cause decay of the timber, which will require replacement. The signs of decaying wood can be seen by water marks on the window or the frame turning soft to touch. It is important to consult an expert to evaluate the situation and determine if any sash window repairs are necessary.

Additionally, with time, the bottom rails can be damaged. Sills that have water marks, or a window that is soft to the touch can be a sign of this. A professional will be required to examine the situation and recommend any necessary replacement of the sash window's seal or replacement.

It is a major concern when triple or double glazed windows start to let noise pollution back into the home. If this occurs the structural integrity could be at risk and the sash window will need to be replaced.

One common sash window repair problem is the sash becoming stuck in the frame. This can be caused by the sash cord being snapped, or it could be a sign of an issue with the sash the ratchets. If it's the latter, then a bit of gentle persuasion is usually enough to get the window open to reopen. Alternatively, the ratchets need to be reset.

This issue can be fixed by taking the sash off and cleaning the tracks. Once the tracks are clean take off any security fittings that may be present and then carefully taking off the sash cords and chains will allow the sash be removed. The staff bead can be sealed with an draught-proof seal in order to minimize the possibility of draughts. This will also improve the paint finish. Decorators caulk can be used to fill in the gap between the sash's sash box and the sash. This will improve the sash's operation and also reduce the risk of draughts.
