Sash Window Repair
Sash windows could be out of balance or even break. Pam is on the lookout for salvaged waving glass, wavy and is always looking for discarded, metal sash weights. She then searches for replacements in the form of washers or nuts to ensure that her window is balanced.
Pam puts each pane in with a rope of glazing compound that she uses to create the rabbet groove, also known as a pocket, around the opening. This helps cut drafts and reduce the cost of heat loss.
Sashes that stick Sashes
When your double-hung window gets stuck in the middle, it's an absolute nightmare. They'll shake during storms and you'll lose view. A window that's too loose may allow air and noise in which can increase your energy costs. Both of these scenarios are not optimal, but they can be corrected by using the right tools and persistence.
A common issue with old windows that are weighted is that paint can accumulate in the channels they slide over, causing them jam. Luckily, most issues with this can be solved by cleaning and lubricating the tracks.
Start by removing the caulking between the window stop (the interior one) and the window frame. Scrape away any paint that has accumulated. Make sure to use a sharp blade, and set up plastic sheets and a vacuum cleaner directly below to keep any paint dust and chips.
Clean the tracks with a dry, clean cloth and apply a silicone lubricant for more smooth sliding. This lubricant is sold at most home improvement shops or on the internet. Then move the sash up or down to test it.
If it continues to jam it could be an issue with the sash cord. Check to see whether the cord is caught or hanging up 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 reason for the jam could be the pin that holds the rail in place has fallen out. This isn't easy to repair, and you'll have to consult a professional in most instances.
You can use a wood softener when the wood is swelling and warped, but there's not a pin. It's a quick drying liquid that can aid in restoring damaged wood, so you'll be able to fix your window sash without needing to remove it completely. After using it, you'll be able to break the two sashes by placing a block of wood on the bottom corner where they meet, and tapping it lightly using an tool.
Draughts
Draughts are a major problem for windows with sash windows that are old particularly during winter months. They are often caused by rotten wood or cracked putty, worn weights for sash or sash cords that aren't balanced which can allow cold air to seep in around the window, making it difficult to keep your home warm. You can stop drafts by filling the gaps with expanding foam, or by utilizing draught-proofing strips that are available at most hardware shops. They are efficient however, you will require replacing them regularly as the foam expands with usage.
Gapseal is a stronger solution that is more permanent. It's a spongy, rubbly seal that can be cut and push in the gaps between the sash window frames. It can be used on its own or with adhesive strips on the top and bottom. This option is quite costly and will have to be applied over the course of your windows' lifespan, but it is an option for the long term and is simple to remove in the event that you want to open the window.
Cling film can also be used to block draughts. Simply roll it up and push it into the gaps surrounding your window. This is a great way to stop draughts however, it could also hinder the sash's movement and even cause a fire. The sash has to be removed to reopen the window, and the clingfilm will need to be applied every time the sash is closed.
A more cost-effective solution is to have your sash windows professionally draught proofed as part of a complete refurbishment service. This may include the fitting of new sash string, staff beads and parting beads in addition to the lubrication and rebalancing the weights, as well as the lubrication and rebalancing the pulley wheel. It may also include painting or staining of the frames and the sashes. This will help restore the sash's function and improve its energy efficiency, while also addressing any minor timber defects. It's less disruptive than taking out the windows, and can reduce drafts, enhance the thermal performance, and drastically reduce costs.
Decay
If your windows are sash and have suffered damage or decay the good news is that they are not necessarily 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 offer a high level of performance for many years. Regular inspections are essential, as is ensuring the wood is adequately ventilated. This will prevent the accumulation of moisture that can cause wood rot.
The majority of the issues you'll face with sash windows are easily visible on a close inspection, but some are harder to spot. Particularly, wood decay is a difficult issue to fix because fungus consumes the wood. While it is possible repair damaged timber however the best method to avoid further decay is to keep the wood dry.
The first step is to remove any paint off the hardware. The bottom rail and meeting rail might require removal from the frame (depending on the position of your sash). The next step is to take off the "pocket covers" that are pieces of wood in the side of the frame low down that allow access to the weights (the parting beads run down the middle of them). It is possible to use a sharp knife to remove them if they're attached by nails or paint. Once the pockets are removed, you can start cutting out any wood rot and apply an excellent water-resistant filler. Once the filler has dried the primer must be applied to guard against further decay.
It is a good idea to inspect inside the window for sashweights to ensure they are balanced. They shouldn't be displaced, or pulling one side more strongly than the other. If they aren't balanced, the sash can fall off its track and could break or damage the frame. You can replace the sashweights with new ones or install an entirely new balance system to stop the sash from moving the wrong direction.
Poor Security
Sash windows are susceptible to wear and damage from weather and wear over time. This can lead to decay of the timber, which requires replacement. The signs of decaying wood can be seen by water marks beneath the window, or the frame turning soft to touch. A professional consultation will be needed to assess the situation and recommend any required sash window repair work.
Similarly, over time the rails at the bottom may become damaged. The sill may show water marks or a window that is soft to the touch could be a sign of this. A professional will be needed to evaluate the situation and recommend any needed replacement of the sash window's seal or replacement.

A common sash window repair problem is when the sash gets stuck in the frame. This could be caused by the sash cord being snapped or it could be an indication of a problem with the sash's ratchets. If it is the latter the gentle persuasion is usually enough to get the window open to reopen. Alternatively, the ratchets will need to be reset.
Removing the sash from the frame and clearing the tracks of 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. 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. The gap between the box and the sash can then be filled with decorators caulk in order to improve the operation of the sash and lessen draughts.
