Sash window repair (recent post by Telegra)

Sash windows can be out of balance or even break. Pam searches the web for wavy glasses that are salvaged and keep an eye out for discarded metal sashweights. She then searches for replacements, such as nuts or washers, to balance her window.

Pam beds each pane with a rope of glazing compound she puts into the rabbet groove, or pocket, which is located around the opening. This prevents drafts and costly heat loss.

Sticking Sashes

It's a nightmare when your double-hung windows become stuck. They'll shake during an icy storm and you'll lose your view. A window that is too loose may allow air and noise in which can increase your energy bills. Both scenarios are not ideal, but both could 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 become jammed. Most of these problems can be resolved by cleaning and oiling the tracks.

Begin by removing the old caulking between the window stop (the one inside) and the window frame. Scrape off any paint that has built up. Make use of a sharp knife and put plastic sheets and dust-collecting vacuum cleaners below the surface to catch any paint dust or chips.

You can then clean the tracks using a dry cloth, then apply a silicone-based lubricant that will make them more gliding. This lubricant is available in a majority of home improvement stores or on the internet. Then, move the sash upwards or down to test it.

If it still jams, there could be an issue with the sash cord. Examine the sash cord to determine if the cord is catching or hanging from the sash, or if it has snapped completely. It is necessary to re-cord the window If this is the case.

Another possible reason for an obstruction is that a pin that holds the rail in place has fallen out. It isn't easy to fix and you will require the help of an expert most of the time.

If a pin isn't falling out, but the wood has gotten warped or swollen, it's a good idea use a wood hardener on it. This liquid dries quickly and can help restore damaged wood. You won't have remove your sash windows to repair them. After you've used it you'll be able pry the two sashes apart by placing a block of wood on the top of the corner where they meet and tapping it lightly with a tool.

Draughts

Draughts can be a major issue for windows with sash windows that are old particularly during winter months. They are often caused by rotten wood, cracked putty, worn weights, or sash cords that are not balanced that allow cold air to get in around the window, making it difficult to keep your home warm. You can reduce the risk of drafts by filling in gaps with expanding foam or using draught-excluding strips found in many hardware stores. These can be effective, although they'll have to be replaced from time to time because the foam expands and gets worn away with time.

A alternative that is more durable is Gapseal, which is a spongy rubbbery seal that you can cut to size and insert into the gaps between the window frames of your sash. It can be used on its own or in conjunction with adhesive strips at the top and bottom. This option is quite costly and will have to be applied over 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 draughts. Simply roll it up and push it into the gaps around your window. This is a great way to stop draughts, but it can also hinder the movement of the sash and even cause a fire. The sash needs to be removed in order to reopen the window, and the clingfilm will need to be reapplied each time the sash is closed.

An alternative that is less expensive is to have your sash windows professionally draught proofed as part of a complete refurbishment service. This could include the replacement of sash cords, staff beads, parting beads, lubrication of the pulley wheels, and rebalancing the weights, and painting or staining the frames and sashes. This can aid in restoring the function of the sash and increase its energy efficiency, as well as fixing any minor wood imperfections. It's less disruptive than removing windows, and can reduce draughts, increase thermal performance and significantly reduce costs.

Decay

If your sash windows have suffered from decay or damage, the good news is they aren't necessarily damaged beyond repair. The wood used in the frames of these windows is generally of very high-quality and with proper restoration they can be restored to provide the best performance for a long time. The key is to conduct regular inspections and ensuring that the timber is well ventilated to prevent moisture build up which can lead to wood to rot.

The majority of the issues you'll encounter with sash windows will be easily visible on a close inspection, but certain issues are more difficult to identify. Particularly, decay of wood is a difficult issue to address because fungus can eat away at the wood. While it is possible to repair damaged timber however the best method to prevent further rot is by keeping the timber dry.

First, clean any paint from the hardware. The bottom rail and the meeting rail might have 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 side, which permit access to the weights, should be removed. These are often nailed in place and stuck with paint, so you will likely require a knife to cut them off. After the pockets have been removed, you can start slicing out any wood decay and apply a high-quality, water-resistant filler. Once the filler has dried the primer must be applied to guard against further decay.

It is a good idea to check the sash weights inside the window as well, to ensure that they are balanced and not swaying one side more than the other. If they're not balanced, the sash can fall off its track and could break or damage the frame. The sash weights could be replaced with new ones or a new balancing mechanism can be fitted that will stop the sashes from swinging towards the wrong side of the window frame.

Poor Security

Sash windows are vulnerable to damage and wear due to weather conditions over time. As time passes, this could result in wood decay that in turn will need to be replaced - an expensive repair that has to be addressed as quickly as is possible. The signs of decaying wood can be seen by water marks under the window, or the frame turning soft to the touch. A professional consultation is required to evaluate the situation and recommend any required sash window repairs repair work.

In the same way, over time, the rails on the bottom can become damaged. This is evident by the presence of water marks on the sill, or the window becoming soft to the touch. A professional consultation will be required to evaluate the situation and recommend any necessary repair or replacement of the sash window's components.

It can be very concerning when triple or double glazing windows begin to let noise pollution back into the home. If this occurs the structural integrity could be at stake and the sash window may require replacement.

One common sash window repair problem is that the sash becomes stuck in the frame. This can be caused by an untidy cord or problems with sash the ratchets. If the problem is with the sash the ratchets, some gentle persuasion is often the best solution.

Removal of the sash from the frame and cleaning the tracks of any dirt or dust will often assist in resolving this issue. After the tracks have been cleaned, removing any security fittings that may be present and then carefully removal of the sash cords as well as chains will allow the sash to be removed. A draught seal may be put on the staff bead to decrease draughts and enhance the appearance of the paint finish. Decorators caulk can be used to fill in the gap between the sash's box and the sash. This will improve the sash's operation and also reduce draughts.
