Sash windows can go out of balance and crack. Pam is on the lookout for salvaged Wavy glass, wavy glass, and keep an eye out for discarded, metal sash weights. She then looks for replacements, such as 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 helps cut drafts and prevent costly heat loss.

Sashes that stick Sashes

It's a nightmare when double-hung windows are stuck. They'll be difficult to see in the event that they shake in a storm. On the other hand, a window that's too loose can let outside air and noise through and your energy costs may increase. Both scenarios are not ideal, but both can be fixed with the proper tools and determination.

A common issue with old weighted sash windows is that paint may build up in the channels that they slide over, causing them blockage. Most of these problems can be resolved by cleaning and oiling the tracks.

Start by removing the caulking between the window stop (the one inside) and the window frame. Scrape away any paint that's built up. Be sure to employ a sharp blade and then put up sheets of plastic and a vacuum cleaner directly below to keep any paint dust and chips.

Clean the tracks using a dry cloth, then apply a silicone-based lubricant to aid in their smoother movement. This lubricant is sold at many home improvement stores or on the internet. You can test it by moving the sash either upwards or downwards.

If it continues to jam, there could be an issue with the sash cord. Verify if the cord is caught or hanging in the sash, or has snapped completely. It is necessary to re-cord the window if this is the situation.

A pin that holds the rail in place could have fallen out. It can be difficult to fix and you will require the help of a professional most often.

If a pin doesn't fall out, but the wood has gotten swollen or warped it's a good idea apply a wood hardener to it. The liquid is quick drying and can repair damaged wood. It's not necessary to take out the windows on your sash to repair them. Once you've used it, you should be able to 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 an Hammer.

Draughts

Draughts are a significant issue for old sash windows particularly during winter months. They are usually caused by decayed wood, cracked putty, or worn sash cords. This allows cold air to enter the window, making it difficult to warm your home. You can prevent drafts by filling the gaps with expanding foam, or using draught-excluding strips that are available in most hardware stores. They're effective however, you will require replacement periodically as the foam expands over time with use.

Gapseal is a stronger solution. It's a spongy rubbbery seal you can cut and then push into the gaps between the window frames of the sash. It can be used alone or with adhesive strips on the top and bottom. This option is fairly expensive and will need to be reapplied over the time of your windows' lifespan, but it is a long-term solution and is easy to remove in the event that you want to open the window.

Cling film can also be used to stop draughts. Simply roll it up and then insert it into all the gaps around your window. This is a good draught-stopper however, it could also block the sash's movement and possibly cause fire.

As part of a complete overhaul you can have your sash window professionally draught-proofed. This could include new sash cords and staff beads, parting beads, lubrication of pulley wheels, and rebalancing the weights, and painting or staining the frames and sashes. This will help restore the sash's function and improve its energy efficiency, in addition to addressing any minor timber defects. It is less disruptive than removing windows and will reduce drafts, enhance the thermal performance, and drastically reduce costs.

Decay


If your windows with sash have suffered decay or damage, the good news is they are not necessarily beyond repair. The timber used in the frames of these windows is usually of very high-quality and, with proper restoration, they can be restored to offer a high level of performance for many years. The key is regularly checking the frames and ensuring that the wood is well ventilated to prevent the accumulation of moisture, which can cause wood to rot.

Most of the problems that you'll encounter with sash windows are readily apparent on close visual examination, however some are harder to spot. Wood decay is difficult to treat, since fungus can eat the wood. It is possible to fix rotten sections of timber, but the best way to stop further decay is to ensure the timber is dry.

First, take off any paint from the hardware. It could be necessary to remove the bottom rail from the frame, and also the rail that joins it (this will depend on the position of the sash). You'll then have to take off the "pocket covers" that are pieces of wood that are located on the sides of the frame that are low down that allow access to the weights (the partsing beads run along the middle of them). You may require a sharp knife to remove them if they are attached by nails or paint. Once the pockets are gone, you can begin to remove any wood rot and then apply a high-quality, water-resistant wood filler. After the filler is dry, a primer coat should be applied to prevent further decay.

It is a smart idea to examine inside the window the weights of the sash to ensure that they are properly balanced. They should not be displaced or pulled one side more strongly than the other. If they're not balanced, the sash can fall off its track and could cause damage to the frame. You can replace the sashweights with new ones, or put in an updated balancing system to prevent the sash from swinging the wrong way.

Poor Security

As time passes sash windows are exposed to the elements, and are prone to deterioration due to weather and general wear. This can lead to the decay of timber, and requires replacement. Wood decay can be detected by water marks under the window or by the frame becoming soft to the touch. A professional consultation will be needed to assess the situation and recommend any needed repair work to the sash window.

Triple and double glazed sash windows do an amazing job at keeping noise pollution out of your home, but it can be a major cause of worry if they begin to let it in. If this happens, the structural integrity of the windows' sash could be in danger and will most likely require to be replaced with a different option.

A common sash repair problem is when the sash becomes stuck in the frame. This could be caused by an sash cord that has snapped or a sign of an issue with the sash's the ratchets. If the problem is related to the sash the ratchets, some gentle pressure is usually enough.

Removal of the sash from the frame and clearing the tracks of dust or dirt can often assist in resolving this problem. Once the tracks are clean take off 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 could be applied around the staff bead in order to reduce the appearance of the paint finish.
