Sash Window Repair

Sash windows may become out of balance or even break. Pam scours the web for salvaged Wavy glass, wavy glass, and keep an eye out for the sash weights that are discarded, made of metal. She then hunts for replacements in the form of washers or nuts 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 helps to reduce drafts and costly heat loss.

Sashes that stick Sashes

It's a nightmare when double-hung windows get stuck. They'll rattle in the event of a storm and you'll lose your view. A window that's too loose could let in external noise and air which could increase your energy bills. Both scenarios are not ideal but they can be fixed by using the right tools and perseverance.

Paint can build up on the channels of old weighted sash window tracks, causing them to jam. Fortunately, the majority of issues with this can be solved through cleaning and lubricating the tracks.

Remove the caulking that was used in the space between the window stop (the one on the inside) and the frame of the window. Then scrape off any paint that has accumulated. Make use of a sharp knife, and put sheets of plastic as well as an air-collecting vacuum cleaner beneath the surface to collect any paint dust or chips.

Then, wipe the tracks with a dry, clean cloth and apply a silicone-based lubricant for more smooth glide. It is available in the majority of home improvement stores or on the internet. You can test it by moving the sash upwards or downwards.

If it continues to jam, the sash cable may be faulty. Examine whether the cord is stuck or hanging from the sash or snapped. If this is the case, you'll need to replace the window's cord.

Another possible cause of a jam is that a pin that holds the rail in place has slipped out. This can be tricky to fix, and you'll need to contact an expert in most cases.

Use a wood hardener when the wood is swelling and warped, but there's not a pin. The liquid is quick drying and can repair damaged wood. You won't have to take out your sash windows to repair them. After using it, you can pry the two sashes apart by placing a piece of wood in the bottom corner of the window where they meet.

Draughts

Draughts can be a concern when you have an old sash window particularly in the winter. They are often caused by rotten wood, cracked putty, worn weights, or sash cords that are not balanced that allow cold air to seep into the window and make it difficult to keep your home warm. There are some options you can take to help prevent draughts in your sash windows, such as filling any gaps with expanding foam or strips to prevent draughts. These can purchase from most hardware stores. They're effective, but they will require replacing them regularly as the foam expands with use.

Gapseal is a more permanent 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 applied on its own or with adhesive strips placed on the bottom and top of the frame. This option is costly and you will need to reapply it over the life of your window. However, it's an effective long-term fix and easy to remove.

Another popular DIY method of draughtproofing is to use cling film that is scrunched up and put into every gap around your window. This is a great draught blocker, but the drawback is that it can stop sash movement completely and could pose an hazard to fire. Furthermore the sash will have to be removed to re-open the door and the cling film will need to be reapplied each time you close the sash.

As part of a complete refurbishment, you can have your window draught-proofed professionally. This can include the installation of new sash strings, parting beads and staff beads as well as the lubrication and rebalancing of the weights and the fluidization and rebalancing of the pulley wheel. It may also include staining or painting of the frames and the sashes. This will bring the sash back to its original function and improve its energy efficiency, and repair any minor defects in the timber. It's less disruptive than removing windows and will reduce draughts, increase the thermal performance, and drastically reduce costs.

Decay

If your windows are sash and have suffered damage or decay the good news is they aren't necessarily damaged beyond repair. The frames of these windows are usually made of high-quality timber. With the right restoration they can be rehabilitated to provide high performance for many years to come. Regular inspections are crucial in ensuring that the wood is adequately ventilated. This will stop the accumulation of moisture that can lead to wood decay.

The majority of issues that arise from sash windows are readily apparent, however some are more difficult to detect. In particular, wood decay is a very difficult problem to treat because fungus consumes the wood. It is possible to repair rotten sections of timber, however the best way to avoid further decay is to ensure that the wood is kept dry.

First, take off any paint from the hardware. It may be necessary to remove the bottom rail from the frame and also the meeting rail (this will depend on the location of the sash). You will then need to remove the "pocket covers" that are pieces of wood that are located on the sides of the frame low down that give access to the weights (the parting beads run down the middle of them). You may need to use a sharp knife to remove them if they're attached by nails or paint. Once the pockets have been removed, you can start slicing out any wood decay and apply an extremely high-quality, water-resistant filler. After the filler has dried, a primer coat should be applied to prevent further decay.

It is a good idea to examine inside the window the sashweights to make sure they are in balance. They should not be in the wrong alignment or pulled one side more strongly than the other. The sash can fall off its track if it is not balanced. This could cause the frame to fall or become damaged. You can replace the sashweights using new ones, or install a new balancing system to stop the sash from swinging the wrong direction.

Poor Security

Sash windows are vulnerable to damage and wear due to weather conditions over time. As time passes, this could cause wood decay, which is then required to be replaced - costly repair that needs to be addressed as soon as possible. The signs of decaying wood can be seen by water marks under the window, or the frame turning soft to touch. It is essential to speak with a professional to assess the situation, and determine if sash window repairs are necessary.

Over time, the bottom rails may also be damaged. This can be spotted 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.

It is a major concern when triple or double glazed windows start to let noise pollution back into the home. If this occurs the structural integrity of the window could be in danger and the sash windows will require replacement.

One common window repair issue for sash windows is the sash becoming stuck in the frame. It could be due to the cord snapping or an issue with the sash's rattles. If it's the latter, then a bit of gentle pressure can help the window to open and then the ratchets will need to be reset.
