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

Pam puts each pane in 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 helps cut drafts and costly heat loss.

Sticking Sashes

It’s a nightmare when double-hung windows become stuck. You’ll lose your view if they rattle during a thunderstorm. A window that’s too loose could let in external noise and air, which will increase your energy costs. Both of these scenarios are not optimal, but they can be fixed by using the right tools and persistence.

A common problem with old windows that are weighted is that paint may get sucked into the channels they slide on, causing them jam. Luckily, most issues with this can be solved 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 off any paint that has accumulated. Make use of a sharp knife and place sheets of plastic 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, and apply a silicone-based lubricant that will make them more gliding. It is available in most home improvement stores, or Sash Window Repair on the internet. Then, move the sash upwards or down to test it.

If it continues to stop it could be faulty. Verify whether the cord is stuck or hanging in the sash or if it’s snapped. If this is the case, you’ll have to re-cord the window.

Another reason for a jam is the pin that holds the rail in place has fallen out. It can be difficult to fix, and you’ll need to contact an expert in the majority of cases.

If a pin doesn’t fall out but the wood has gotten warped or swollen it’s a good idea to apply a wood hardener to it. It’s a quick drying liquid that can help to restore damaged wood, and you’ll be able repair your window without having to remove it completely. After you’ve used it, you can take apart the two sashes by placing a piece of wood on the bottom corner of the window where they meet.

Draughts

Draughts are a significant issue for old sash windows particularly during winter months. They are often caused by rotten wood, cracked putty, worn sash cords or unbalanced weights that allow cold air to get in around the window, making it difficult to keep your home warm. There are a few things you can do to stop draughts from coming through your windows with sash, for example, filling any gaps with expanding foam or using strips to prevent draughts. These can purchase at many hardware stores. These are effective however, you will require replacement periodically because the foam expands with use.

A more permanent solution is Gapseal which is a rubbery spongy seal that can be cut to the desired size and then insert into the gaps between the sash window frame. It can be used on its own or in conjunction with adhesive strips on the top and bottom of the frame. This option is costly and you will need to apply it several times over the course of the life of your window. But, it’s a long-term fix and is simple to remove.

Cling film can also be used to stop draughts. Simply scrunch it and then insert it into the gaps surrounding your window. This is a reliable draught stopper, but the drawback is that it can stop sash movement completely and may be an hazard to fire. The sash must be removed to open the window and the clingfilm will need to be reapplied each time the sash is closed.

A better option is to have your sash windows professionally draught proofed as part of a general refurbishment service. This could include the replacement of sash cords, staff beads, parting beads, lubrication of pulley wheels, and rebalancing the weights, in addition to staining or painting the frames and sashes. This will bring the sash back to its original function, improve its energy efficiency and correct any minor defects in the timber. It’s less disruptive than replacing the windows altogether and will significantly reduce draughts as well as improve the thermal efficiency of your home.

Decay

If your windows are sash and have suffered decay or damage, the good news is they aren’t necessarily unfixable. The timber used in the frames of these windows is typically of a very high quality and, with the right restoration, can be revived to provide the best performance for many years. Regular inspections are key and so is making sure the wood is adequately ventilated. This will stop the accumulation of moisture that can cause wood decay.

The majority of the issues you will encounter with sash windows are readily apparent on close visual examination, however some are harder to spot. Particularly, decay of wood is a difficult issue to fix because fungus can eat away at the wood. Although it is possible to repair window damaged timber but the best way to prevent further rot is by keeping the timber dry.

The first thing to do is to clean any paint from the hardware. It may be necessary to remove the bottom rail from the frame, and the rail for meeting (this will depend on the position of the sash). The next step is to take off the “pocket covers” which are pieces of wood in the side of the frame low down that provide access to the weights (the parting beads run down the middle of them). You may need to use a sharp knife for removing them if they’re painted or nailed into place. Once the pockets are removed you can begin to chisel away any wood rot, and apply a good quality water-resistant wood filler. After the filler has dried, a primer coat should be applied to prevent further decay.

It is a smart idea to check inside the window the sashweights to ensure they are properly balanced. They shouldn’t be displaced, or pulling one side more than the other. If they aren’t balanced, the sash can drop off its track and could break or damage the frame. The sash weights can be replaced with new ones or a new mechanism for balancing can be fitted, which will stop the sashes from swinging towards the opposite side of the window frame.

Poor Security

Over time sash windows are exposed to the elements, and are prone to deterioration from weather and general wear. Over time, this can cause wood decay, which in turn will need to be replaced – an expensive repair that has to be addressed as quickly as possible. Water marks on the window or a softened frame could indicate decay of the wood. A professional consultation will be needed to assess the situation and recommend any necessary sash window repair work.

In time the rails at the bottom can also be damaged. This is evident by the presence of water marks on the sill or by the window becoming soft to the touch. A professional is required to assess the situation, and recommend any necessary replacement of the sash window’s seal or replacement.

Double and triple-glazed Sash windows do an incredible job of keeping noise pollution out of the home, but it can be a major cause of worry when they begin to let it back in. If this happens the structural integrity of the window could be at risk and the sash windows will require replacement.

One common problem with repairing sash windows is when the sash gets stuck in the frame. This can be caused by an sash cord that has snapped, or it could be an indication of a problem with the sash’s ratchets. If the latter is the case the gentle pressure can help the window open again – or alternatively, the ratchets will need to be reset.

Removing the sash from the frame and removing the tracks of dust or dirt can often assist in resolving this issue. After cleaning the tracks, remove any security fittings and then remove the sash cords or chains. A draught seal could 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 sash can be filled with decorators caulk in order to improve sash operation and reduce the risk of draughts.
