Sash Window Repair

Sash windows can be out of balance and even break. Pam scours the web for salvaged Wavy glass, wavy glass, and is always looking for the sash weights that are discarded, made of metal. She then hunts for replacements in the form of nuts or washers to balance her window.

Pam will bed each pane by putting a rope of glazing material into the rabbet groove, or pocket around the opening. This reduces drafts and expensive heat loss.

Sticking Sashes

If your double-hung window becomes stuck in the middle, it's a nightmare. They'll shake during an icy storm, and you'll lose your view. On the other hand, a window that's too loose can let outside air and noise through and your energy bills can increase. Both scenarios are not optimal, but both can be addressed with the proper tools and perseverance.

Paint can build up on the channels of old weighted sash window tracks, causing them to become jammed. The majority of these issues can be resolved by cleaning and oiling 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 to make use of a sharp blade and set up plastic sheets and a vacuum cleaner right below to catch any paint dust and chips.

Then, wipe the tracks with a dry, clean cloth and apply a silicone-based lubricant for better gliding. This lubricant is available at many home improvement stores or online. You can test it by dragging the sash upwards or downwards.

If it continues to jam, there could be an issue with the sash cord. Examine the sash cord to determine if the cord is catching or hanging in the sash, or if it has snapped completely. If this is the case, you'll need to replace the window's cord.

Another possible cause of an obstruction is that a pin that holds the meeting rail in place has fallen out. This isn't easy to fix, and you'll need to call an expert in most instances.

Use a wood hardener when the wood is swelling and warped but there's no pin. This liquid dries quickly and can restore damaged wood. It's not necessary to take out your sash windows to repair them. After using it, you can pry apart the two sashes by placing a piece of wood in the bottom corner of the window where they meet.

Draughts

Draughts are a significant issue for old sash windows particularly in winter months. They are usually caused by decaying wood, broken putty or worn cords for sash. This causes cold air to enter the window, making it difficult to warm your home. There are some things you can do to stop draughts from coming through your windows that are sash, like filling any gaps with foam that expands or draught excluder strips that you can buy at most hardware stores. These are effective, although they'll have to be replaced periodically as the foam expands and wears away with wear and use.

Gapseal is a longer-lasting solution that is more permanent. It's a spongy, rubbly seal that can be cut and push into the gaps between the sash window frames. It can be used alone or in conjunction 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's a long-term fix and is easy to remove.

Another popular DIY method of draughtproofing is to use cling wrap that is rolled up and placed into the gaps around your window. This is an effective draught stopper but the downside is that it can stop sash movement completely and could pose risky for fire. The sash has to be removed to open the window and the clingfilm needs to be reapplied every time the sash is closed.

As part of a general renovation it is possible to have your sash window professionally draught-proofed. This can include new sash cords, parting beads, staff beads, lubrication for the pulley wheels and rebalancing of the weights, in addition to staining or painting the frames and sashes. This will help restore the function of the sash, and increase its energy efficiency, as well as dealing with any minor timber imperfections. It's less disruptive than removing windows, and can reduce draughts, increase the thermal efficiency and dramatically reduce costs.

Decay

The good thing is that your sash window frames are not beyond repair if they have been damaged or deteriorated. The timber used in the frames of these windows is usually of very high-quality and with proper restoration they can be restored to provide a high level of performance for many years. Regular inspections are essential and so is making sure the wood is properly ventilated. This will stop the accumulation of moisture that can cause wood decay.

The majority of the issues that you'll face with sash windows are readily apparent on close visual inspection, but some are harder to spot. Wood decay is a challenge to repair, since fungus eats the wood. It is possible to repair wood that is rotten, however, the best method to avoid further rot is to make sure the wood is kept dry.

First, remove any paint from the hardware. The bottom rail and the connecting rail might have to be removed from the frame (depending on the location of your sash). You'll then have to remove the "pocket covers" which are bits of wood that are located on the sides of the frame lower down that give access to the weights (the parting beads run through the middle of them). It is possible to use a sharp knife to take them if they're fixed or painted. Once the pockets have been removed, you can start slicing out any wood decay and apply an extremely high-quality water-resistant filler. Once the filler has dried the primer must be applied to prevent further decay.

It is an excellent idea to examine the sash weights within the window as well to make sure they are balanced and not swaying one side more than the other. The sash could slide off the track if they are not properly balanced. This could cause the frame to crack or become damaged. The sash's weights can be replaced with new ones or a new mechanism for balancing can be fitted that will stop the sashes from swinging to the opposite side of the window frame.

Poor Security

As time passes sash windows become exposed to the elements, and are prone to deterioration from weather and general wear. This can cause decay of the timber, which requires replacement. Wood decay can be spotted by water marks under the window or the frame becoming soft to touch. It is crucial to speak with an expert to assess the situation and determine if sash window repairs are necessary.

In time, the bottom rails may also be damaged. This can be spotted by the presence of water marks on the sill, or the window becoming soft to the touch. A professional consultation may be required to evaluate the situation and recommend any necessary repair or replacement of sash window components.

It is a major concern when double glazed window repairs and triple windows are glazed and start to allow noise pollution back into your home. If this occurs, the structural integrity may be in danger and the sash windows will have to be replaced.

One common problem with repairing sash windows is that the sash becomes stuck in the frame. This can be caused by a snapped cord or a problem with sash ratchets. If the issue is with the sash's the ratchets, some gentle persuasion is often the best solution.

The sash should be removed from the frame and removing the tracks of any dirt or dust will often aid in resolving this problem. After cleaning the tracks, remove any security fittings, and then remove the chains or cords that hold the sash. A draught seal may be put on 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 be filled with decorators caulk to improve the operation of the sash and decrease the risk of draughts.
