Sash Window Repair

Sash windows can be out of balance or even break. Pam browses the internet for salvaged wavy glasses and keeps an eye open for discarded metal sashweights. She then hunts for replacements in the form of nuts or washers to balance her window.

Pam beds each pane with a rope of glazing compound that she puts into the rabbet groove, also known as a pocket, which is located around the opening. This reduces drafts and expensive heat loss.

Sashes that stick Sashes

If your double-hung window becomes stuck in the middle, it's a nightmare. You'll lose your view when they squeak in a storm. A window that's too loose can let air and noise in which can increase your energy costs. Both scenarios are not optimal but they can be rectified by using the appropriate tools and persistence.

Paint can get splattered on the channels of old weighted sash window tracks, causing them to jam. Fortunately, most issues related to this can be resolved by cleaning and lubricating the tracks.

Start by removing the old caulking between the window stop (the interior one) and the window frame. Scrape away any accumulated paint. Make use of a sharp knife, and place 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 using a dry cloth, and apply a silicone lubricant to ensure better gliding. This lubricant is available at most home improvement shops or online. You can test it by dragging the sash upwards or downwards.

If it still jams it could be an issue with the sash cord. Check to see whether the cord is stuck or hanging from the sash, or if it's snapped. You'll need to re-cord your window in the event of this.

Another reason for a jam is the pin that holds the rail in place has fallen out. This isn't easy to fix, and you'll need to consult an expert in the majority of cases.

Use a wood hardener in the event that the wood is swollen and warped, but there's not a pin. This liquid dries quickly and can repair damaged wood. It's not necessary to remove your sash windows in order to repair them. After you've used it you should 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 with the Hammer.

Draughts

Draughts can be a major issue for windows with sash windows that are old, especially in the winter months. They are often caused by decayed wood, broken putty or worn sash cords. This causes cold air to enter the window, making it more difficult to heat your home. There are some things you can do to help prevent draughts in your windows that are sash, like filling any gaps with expanding foam or strips to prevent draughts. These can purchase from most hardware stores. They are efficient however you'll need to replace them periodically because the foam expands with use.

A more permanent solution is Gapseal, which is a rubbery spongy seal that you can cut to the size you require and then put into the gaps between the sash window frame. It can be used by itself or with adhesive strips at the top and bottom. This is costly and you will need to reapply it over the course of the life of your window. However, it is an affordable fix that is easy to remove.

Cling film can also be used to block drafts. Simply scrunch it and then insert it into all the gaps that surround your window. This is a good draught-stopper however it could also block the sash's movement and cause a fire. The sash has to be removed in order to reopen the window, and the clingfilm will need reapplied every time the sash is closed.

A better option is to have your windows draught-proofed as part of a complete 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 staining or painting of the frames and sashes. This could bring the sash back to its original function and improve its energy efficiency and fix any minor imperfections in the timber. It is much less disruptive than replacing the windows altogether and will significantly reduce draughts as well as improve your home's thermal performance.

Decay

The good news is that frames for sash windows aren't damaged beyond repair even if they have been damaged or decayed. The wood used in the frames of these windows is generally of a very high quality and with proper restoration they can be restored to provide an excellent level of performance for a long time. The key is regular inspections and ensuring that the timber is well ventilated to prevent moisture accumulation, which can cause wood rot.

The majority of issues that arise from sash windows are readily evident, but some are more difficult to spot. Wood decay is difficult to repair, since fungus eats the wood. While it is possible to repair wood that is rotten but the best way to prevent further decay is to keep the wood dry.

First, remove any paint from the hardware. The bottom rail and meeting rail could require removal from the frame (depending on the location of your sash). The "pocket covers" are tiny pieces of wood on the frame's side that permit access to the weights, should be removed. These can sometimes be fixed by nailing them in place and then securing them with paint, so you'll likely require an instrument to break them out of the way. Once the pockets are gone, you can begin to chisel away any wood that is rotting, and apply a good quality water-resistant wood filler. After the filler has dried, a coat of primer should be applied to guard against further decay.

It is recommended to inspect the sash's weights inside the window too to ensure that they are properly balanced and not pulling one side more than the other. The sash could fall off its track if it is not balanced. This could cause the frame to fall or be damaged. The sash's weights can be replaced with new ones or a new mechanism for balancing could be fitted, which will stop the sashes from swinging to the wrong side of the window frame.

Poor Security

As time passes sash windows are exposed to the elements and susceptible to deterioration from weather and general wear. This can cause decay of timber, and requires replacement. Water marks under the window or a frame that is soft can indicate wood decay. It is essential to speak with an expert to evaluate the situation, and determine if any sash window repairs are necessary.

Additionally, with time, the rails at the bottom may become damaged. The sill may show water marks, or a window that is soft to the touch may indicate this. A professional consultation may be required to determine the situation and recommend any necessary resealing or replacement of the sash window's components.

Double and triple-glazed Sash windows do an incredible job of keeping noise pollution out of your home, and it could be a real cause for worry when they begin to let it in. If this is happening, the structural integrity of windows' sash could be at risk and it is likely to need to be replaced with a different option.

A common window repair issue for sash windows is when the sash gets stuck in the frame. This could be caused by a snapped sash cord, or it could be the result of an issue with the sash ratchets. If the latter is the case scenario, a little gentle persuasion is usually enough to get the window to open and then the ratchets will need to be reset.

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 can then be put on the staff bead in order to reduce draughts and improve the appearance of the paint finish. The gap between the box and the sash can then be filled with decorators caulk to improve the operation of the sash and lessen the risk of draughts.
