Sash Window Repair

Sash windows can get out of balance and crack. Pam is on the lookout on the internet for salvaged wavy glasses and keep an eye out for discarded metal sashweights. She then looks for replacements, like washers or nuts, to help balance her window.

Sashes that stick Sashes

When your double-hung window gets stuck and shatters, it's a nightmare. You'll lose sight if they rattle during a thunderstorm. A window that's too loose could let air and noise in which could increase your energy costs. This is neither optimal, but both can be solved with the right tools and a little determination.

Paint can get splattered on the channels of the old weighted sash window tracks, which can cause them to jam. Fortunately, the majority of issues with this can be resolved by cleaning and lubricating the tracks.

Remove the old caulking from the space between the window stop (the one on the inside) and the frame of the window. Scrape away any paint that's built up. Make sure you make use of a sharp blade and then set up sheets of plastic and a vacuum cleaner right below to catch any paint dust and chips.

You can then clean the tracks with a dry cloth, and apply an oil based on silicone to help them slide better. This lubricant is sold at many home improvement stores or on the internet. Then move the sash up or down to test it.

If it continues to jam, there could be an issue with the sash cord. Verify if the cord is caught or hanging up in the sash, or if it has snapped off completely. If this is the situation, you'll need to re-cord the window.

Another possible cause of the jam could be that a pin that holds the meeting rail in place has fallen out. It can be difficult to repair, and you'll have to consult an expert in most cases.

If a pin isn't falling out but the wood has gotten swollen or warped, it's a good idea to apply a wood hardener to it. The liquid is quick drying and can restore damaged wood. You won't have to remove your sash windows to repair them. After 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 tool.

Draughts

A more permanent solution is Gapseal, a sponge-like seal that can be cut to the size you require and then put into the gaps between your sash window frame. It can be used alone or in conjunction with adhesive strips at the top and bottom. This option is fairly expensive and will need to be reapplied throughout the time of your windows' lifetime but it does offer an option for the long term and is easy to take off if you want to open the window.

Cling film can also be used to stop drafts. Simply scrunch it and then insert it into the gaps surrounding your window. This is a good draught-stopper however it could also hinder the sash's movement and cause a fire. Furthermore the sash will have to be removed to open the window again and the cling film has to be applied every time you close the sash.

A better option is to have your windows draught-proofed as part of a general refurbishment service. This may include the fitting of new sash string, parting beads and staff beads as well as the lubrication and rebalancing of the weights and the fluidization and rebalancing of the pulley wheel. It may also involve painting or staining of the frames and the sashes. This can restore the sash to its original purpose and increase its energy efficiency and correct any minor imperfections in the wood. It's less disruptive than removing windows and will reduce draughts, increase thermal performance and Sash window repair significantly reduce costs.

Decay

The good news is that your windows' sash frames aren't damaged beyond repair even if they have been damaged or degraded. The timber used in the frames of these windows is typically of a very high quality and, with proper restoration, they can be restored to offer an excellent level of performance for many years. The key is regularly checking the frames and ensuring that the wood is properly ventilated to avoid moisture build up which can lead to wood decay.

Most of the problems you'll encounter with sash windows will be evident upon close inspection, but some are more difficult to detect. Particularly, wood decay is a difficult issue to fix because fungus consumes the wood. It is possible to fix rotten sections of timber, but the best way to avoid further decay is to ensure that the timber is dry.

The first step is to clean any paint off the hardware. The bottom rail and the connecting rail may require removal from the frame (depending on the position of your sash). The "pocket covers" are tiny pieces of wood placed on the frame's side that allow access to the weights, should be removed. You may require a sharp knife for removing them if they're painted or nailed into place. After the pockets have been removed, you can begin slicing out any wood decay and apply a high-quality water-resistant filler. Once the wood filler has dried the primer coat must be applied to prevent further decay.

It is a smart idea to inspect inside the window the weights of the sash to ensure that they are properly balanced. They shouldn't be in the wrong alignment, or pulling one side harder than the other. The sash may slide off the track if it is not properly balanced. This could cause the frame to fall or even be damaged. The sash weights can be replaced with new ones or a new balance mechanism can be installed to stop the sashes from swinging to the opposite side of the window frame.

Poor Security

Sash windows are prone to damage and wear due to weather conditions over time. Over time, this can cause wood decay, which is then required to be replaced - costly repair that needs to be addressed as soon as possible. Wood decay can be detected by water marks on the window, or the frame turning soft to the touch. A professional consultation is needed to assess the situation and recommend any necessary sash window repair work.

Similarly, over time the rails on the bottom can become damaged. The sill may show water marks or a window which is soft to the touch may be a sign of this. A professional consultation will be required to assess the situation and recommend any needed repair or replacement of the sash window's components.

Triple and double glazed sash windows do an amazing job of keeping noise pollution out of your home, but it can be a cause for worry if they begin to let it back in. If this is happening the structural integrity of the sash windows may be at risk, and they will likely need to be replaced by a different option.

A common issue with repairing sashes is when the sash becomes stuck in the frame. This can be caused by a snapped cord or problems with sash ratchets. If the issue is with the sash's rats, a bit of gentle persuasion will usually work.

This issue can be solved by taking off the sash and cleaning the tracks. After cleaning the tracks, remove any security fittings and carefully remove the sash cords or chains. The staff bead may be sealed with a draught-proof seal to reduce the risk of draughts. This can also improve the finish of paint. Decorators caulk can be used to fill in the gap between the sash's sash box and the sash. This will enhance the operation of the sash and also reduce the possibility of draughts.
