Sash Window Repair
Sash windows can be out of balance and even break. Pam searches the internet for salvaged, wavy glass and keep an eye out for scraps of sash weights made of metal. She then looks for replacements, like nuts or washers to help balance her window.
Pam will bed each pane by placing an edging rope into the rabbet groove or pocket around the opening. This reduces drafts and expensive heat loss.
Sashes that stick Sashes
It's a nightmare when your double-hung windows are stuck. You'll lose sight in the event that they shake in a storm. On the other side, a window that's too loose will allow external air and noise through and your energy bills can increase. Neither scenario is ideal, but both can be solved with the appropriate tools and determination.
Paint can build up on the channels of the old weighted sash window tracks, causing them to jam. The majority of these issues can be resolved 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. Scrape away any paint that has accumulated. Make sure to use a sharp blade, and then put up plastic sheets and a vacuum cleaner right below to catch any paint dust and chips.
Then, wipe the tracks with a dry cloth and apply a silicone lubricant to ensure more smooth glide. The lubricant can be found in a majority of home improvement stores or on the internet. You can test it by moving the sash upwards or downwards.
If it continues to jam the sash cable could be defective. Check to see whether the cord is caught or hanging up in the sash, or if it has snapped off completely. You'll have to re-cord your window in the event of this.
A pin that holds the rail in place could have been ripped out. It can be difficult to repair, and you'll have to call an expert in the majority of instances.
You can use a wood softener when the wood is swelling and warped, but there's not a pin. This liquid dries quickly and can help restore damaged wood. It's not necessary to take out your sash windows to repair them. Once you've used it, you'll be able 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 can cause problems with sash windows that are old, especially during the winter. They are often caused by rotten wood, broken putty or worn cords for sash. This allows cold air to get inside the window, making it more difficult to warm your home. There are several ways to help prevent draughts in your windows with sash, for example, filling any gaps with expanding foam or draught excluder strips that you can buy at most hardware stores. They're effective however, you will need to replace them periodically because the foam expands with use.
A alternative that is more durable is Gapseal, a spongy rubbbery seal that can be cut to the size you require and then insert into the gaps between your sash window frame. It can be used on its own or with adhesive strips at the top and bottom. This is a bit costly and will have to be reapplied over the course of your windows' lifespan, but it is an option for the long term and is simple to remove in the event that you want to open the window.
Cling film can also be used to block drafts. Simply scrunch it and then insert it into all the gaps surrounding your window. This is an effective draught stopper but the downside is that it can block sash travel completely and could pose a fire hazard. The sash must be removed in order to reopen the window, and the clingfilm will need to be applied every time the sash is closed.
A better option is to have your windows draught-proofed as part of a comprehensive refurbishment service. This could include the installation of new sash strings staff beads and parting beads in addition to the lubrication and rebalancing the weights, as well as the oiling and rebalancing of the pulley wheel. It could also involve painting or staining of the frames and sashes. This can help to restore the sash's function and improve its energy efficiency, as well as fixing any minor wood defects. It's much less disruptive than replacing windows completely and will dramatically reduce draughts and improve your home's thermal performance.
Decay
If your windows are sash and have suffered damage or decay the good news is that they aren't necessarily damaged beyond repair. The timber used to construct the frames of these windows is generally of a very high quality and, with the right restoration, can be revived to provide a high level of performance for a long time. Regular inspections are key in ensuring that the wood is adequately ventilated. This will stop the accumulation of moisture that can cause wood decay.
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 repair, since fungus can eat the wood. It is possible to repair wood that is rotten, but the best way to stop further rot is to make sure the timber is kept dry.
First, clean any paint from the hardware. The bottom rail and meeting rail could have to be removed from the frame (depending on the location of your sash). You'll then have to remove the "pocket covers" that are pieces of wood on the side of the frame that are low down that allow access to the weights (the parting beads run through the middle of them). These can sometimes be nailed in place and stuck with paint, so you'll probably need to use a knife to get them out of the way. After the pockets have been removed, you can begin chiseling out any wood rot and apply a high-quality water-resistant filler. After the filler is dry it is recommended that a primer coat be applied to stop further decay.
It is a good idea to check the sash's weights inside the window as well to ensure that they are in balance and not swaying one side more than the other. If they are not balanced the sash is liable to drop off its track and cause damage to the frame. You can replace the sashweights using new ones, or put in a new balancing system to prevent the sash from swinging in the wrong direction.
Poor Security
Over time, sash windows can become exposed to the elements, and are prone to damage from weather and general wear. Over time, this can lead to timber decay which is then required to be replaced - a costly repair that needs to be dealt with as soon as is possible. Wood decay can be spotted by water marks under the window or by the frame becoming soft to touch. A professional consultation will be required to evaluate the situation and recommend any necessary sash window repair work.
Over time, the bottom rails may also be damaged. Water marks on the sill, or a window that is soft to the touch can be an indication of this. A professional will be needed to assess the situation, and recommend any repair of sash windows or replacement.
Triple and double glazed Sash windows do an incredible job at keeping noise out of the home, but it can be a major cause of worry if they begin to let it in. If this occurs, the structural integrity may be at stake and the sash windows will require replacement.
A common window repair issue for sash windows is that the sash becomes stuck in the frame. It could be due to an untidy cord or an issue with the sash's rattles. If the issue is with the sash's the ratchets, some gentle persuasion is often the best solution.
This issue can be fixed by taking off the sash and cleaning the tracks. After cleaning the tracks, remove any security fittings and then remove the chains or sash cords. A draught seal may be applied around the staff bead in order to reduce draughts and enhance the appearance of the paint finish. The gap between the box and the sash can then be filled with decorators caulk in order to improve the operation of the sash and decrease draughts.
