Sash Window Repair

Sash windows can be out of balance and even break. Pam is on the lookout for salvaged, wavy glass and keep an eye out 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 will bed each pane by placing an edging rope into the rabbet groove, or pocket around the opening. This reduces drafts and expensive heat loss.

Sashes that stick Sashes

It's a nightmare if your double glazing near me-hung windows become stuck. They'll be difficult to see when they squeak during a storm. On the other hand, a window that's too loose will let external air and noise in, and your energy bills could increase. Neither scenario is ideal, but both could be solved with the appropriate tools and perseverance.

Paint can build up on the channels of old weighted sash window tracks, causing them to become jammed. Most of these problems can be resolved by cleaning and oiling the tracks.

Start by removing the old caulking that was between the window stop (the one inside) and the window frame. Scrape off any paint that has been accumulating. Make sure to make use of a sharp blade and then put up plastic sheets and a vacuum cleaner right below to keep any paint dust and chips.

Then, clean the tracks with a dry, clean cloth and apply a silicone lubricant for better sliding. You can purchase this at many home improvement stores or on the internet. Then, you can move the sash up or window repairs down to test it.

If it continues to block it could be faulty. Verify whether the cord is stuck or hung in the sash or if it's snapped. If this is the situation, you'll need to replace the window's cord.

Another reason for a jam is the pin that holds the meeting rail in place has slipped out. It can be difficult to repair, and you'll have to call a professional in most instances.

If a pin isn't falling out but the wood has become warped or swollen it's recommended to use a wood softener on it. It's a fast 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 can pry apart the two sashes by placing a piece of wood in the bottom corner of the window where they meet.

Draughts

Draughts can be a concern with sash windows that are old particularly in winter. They can be caused by decayed wood, broken putty or worn cords for sash. This causes cold air to seep around the window, making it difficult to heat your home. You can prevent drafts by filling in gaps with expanding foam or by using draught-proof strips that are found in many hardware stores. They are efficient, but they will require replacing them regularly as the foam expands with usage.

Gapseal is a more permanent solution that is more permanent. It's a spongy, rubbbery seal you can cut and push into the gaps between the window frames of the sash. It can be used on its own or in conjunction with adhesive strips at the top and bottom. This is costly and you'll need to apply it again throughout the life of your window. But, it's an effective long-term fix and simple to remove.

Another popular DIY method of draughtproofing is to use cling wrap that is rolled up and put into every gap around your window. This is a great draught blocker, but the drawback is that it could block sash travel completely and may be risky for fire. Furthermore, the sash will need to be removed to open the window again and the cling film has to be applied each time you close the sash.

As part of a comprehensive overhaul you can have your window draught-proofed professionally. This may include the fitting of new sash strings staff beads and parting beads in addition to the lubrication and rebalancing the weights, as well as the oiling and rebalancing of the pulley wheel. It could also involve staining or painting the frames and the sashes. This will help restore the function of the sash, and increase its energy efficiency, in addition to fixing any minor wood defects. It's much less disruptive than replacing the windows entirely and can significantly reduce draughts as well as improve your home's thermal efficiency.

Decay

The good news is that your sash window frames are not beyond repair if they have been damaged or degraded. The frames of these windows are typically made of high-quality timber. If you can restore them properly they can be rehabilitated to ensure high performance for many more years. Regular inspections are key in ensuring that the wood is adequately ventilated. This will help prevent the accumulation of moisture that can cause wood rot.

The majority of problems that arise from sash windows are readily apparent, however some are more difficult to detect. Particularly, decay of wood is a difficult issue to address because fungus can eat away at the wood. It is possible to repair damaged sections of timber however, the best method to stop further decay is to ensure that the timber is kept dry.

The first thing to do is to clean any paint off the hardware. The bottom rail and the meeting rail may require removal from the frame (depending on the position of your sash). The "pocket covers" are tiny pieces of wood placed on the frame's sides that permit access to the weights, should be removed. These are often nailed in place and stuck with paint, so you will probably need to use an instrument to break them loose. Once the pockets have been removed, you can start cutting out any wood rot and apply an excellent water-resistant filler. After the filler has dried, the primer must be applied to prevent further decay.

It is an excellent idea to examine the sash's weights inside the window too to ensure that they are properly balanced and not swaying one side more than the other. If they're not balanced, the sash could drop off its track and could cause damage to the frame. The sash's weights can be replaced with new ones or a new balancing mechanism can be fitted that will stop the sashes from bouncing to the opposite side of the window frame.

Poor Security

Over time sash windows become exposed to the elements and prone to deterioration from weather and general wear. As time passes, this could result in wood decay that is then required to be replaced - an expensive repair that has to be dealt with as soon as possible. Water marks under the window or a frame that is soft can indicate wood decay. It is important to consult a professional to assess the situation and determine if any sash window repairs are necessary.

In the same way, over time, the rails at the bottom may become damaged. This can be seen 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 needed repair or replacement of sash window components.

It is a major concern when triple and double windows are glazed and start to allow noise pollution back into your home. If this happens the structural integrity could be at stake and the sash window will require replacement.

One common problem with repairing sash windows is the sash becoming stuck in the frame. This can be caused by an untidy cord or a problem with sash ratchets. If the latter is the case the gentle persuasion can usually help the window open to reopen. Alternatively, the ratchets must be reset.

The sash should be removed from the frame and clearing the tracks of any dust or dirt can often aid in resolving this issue. Once the tracks are clean, removing any security fittings that could be present. Lastly, carefully removal of the sash cords as well as chains will allow the sash be removed. A draught seal can then be placed around the staff bead to reduce the appearance of the paint finish. Decorators caulk can be used to fill in the gap between the sash's sash box and the sash. This will improve the sash's operation and reduce the possibility of draughts.
