Start by removing the caulking that was between the window stop (the one inside) and the window frame. Then scrape off any accumulated paint. Make use of a sharp knife, and put plastic sheets and dust-collecting vacuum cleaners below the surface to collect any paint dust or chips.

You can then clean the tracks using a dry cloth, and then apply a silicone-based lubricant to help them slide better. The lubricant can be found in a majority of home improvement stores or online. Then, move the sash upwards or down to test it.

If it continues to stop, the sash cable may be defective. Check to see whether the cord is tangled or hanging from the sash, or if it's snapped. If this is the situation, you'll need to replace the window's cord.

Another reason for an obstruction is that a pin that holds the rail in place has slipped away. It can be difficult to fix and you will need to call in a professional the majority often.

If a pin isn't falling out but the wood has gotten swollen or warped it's a good idea use a wood softener on it. This liquid will dry quickly and can restore damaged wood. It's not necessary remove your sash windows to repair them. After you've used it, you can pry off the two sashes by placing a piece of wood on the lower corner of the window where they meet.

Draughts

Draughts can be a concern when you have an old sash window, especially during the winter. Often caused by rotten timbers cracks, cracked putty, deteriorated sash cords or unbalanced weights, they can allow cold air to get into the window and make it difficult to keep your home warm. There are some things you can do to stop draughts from coming through your windows with sash, for example, filling any gaps with foam that expands or draught excluder strips that you can purchase from most hardware stores. They're effective however you'll require replacement periodically because the foam expands with use.

It can be used on its own or with adhesive strips on the top and bottom. This option is quite costly and will need to be reapplied throughout the course of your windows' lifespan, but it is a long-term solution and is simple to remove if you want to open the window.

Cling film can also be used to stop drafts. Simply roll it up and then insert it into the gaps surrounding your window. This is a great draught blocker, window repair but the drawback is that it could stop sash movement completely and could pose an hazard to fire. The sash needs to be removed to reopen the window and the clingfilm must be reapplied every time the sash is closed.

As part of a complete overhaul it is possible to have your sash window professionally draught-proofed. This could include new sash cords, staff beads, parting beads, lubrication for the pulley wheels, and rebalancing the weights, and staining or painting the frames and sashes. This could restore the sash to its original purpose and improve its energy efficiency and correct any minor defects in the timber. It's less disruptive than removing the windows and will reduce draughts, increase thermal performance and significantly reduce costs.

Decay

The good news is that sash window frames are not beyond repair if they have been damaged or decayed. The wood used in the frames of these windows is generally of a very high quality and, with the right restoration, can be restored to offer the best performance for many years. The key is regular inspections and ensuring that the timber is properly ventilated to stop moisture accumulation which can lead to wood to rot.

In particular, wood decay is a difficult problem to treat because fungus can eat away at the wood. While it is possible repair wood that is rotten however the best method to prevent further rot is by keeping the wood dry.

The first step is to strip any paint from the hardware. It may be necessary to remove the bottom rail from the frame and also the rail that joins it (this will depend on the location of the sash). The "pocket covers", which are small pieces of wood that are placed on the frame's sides that permit access to the weights should be removed. These are often put in place by nails and then covered with paint, so you will likely require a knife to get them loose. After the pockets have been removed, you can begin to remove any wood that is rotting, and then apply a high-quality water-resistant wood filler. After the filler has dried the primer coat must be applied to stop further decay.

It is recommended to inspect the sash weights inside the window, too to make sure they are properly balanced and not pulling one side more than the other. The sash can slide off the track if they are not properly balanced. This could cause the frame to crack or be damaged. The sash weights can be replaced with new ones or a new mechanism for balancing could be fitted to stop the sashes from swinging towards the wrong side of the frame.

Poor Security

Sash windows are prone to wear and damage from weather and wear over time. This can cause decay of timber, and requires replacement. Wood decay can be detected by water marks on the window, or by the frame becoming soft to touch. It is important to consult a professional to assess the situation, and determine if sash window repairs are necessary.

In the same way, over time, the rails on the bottom can become damaged. Water marks on the sill or a window that is soft to the touch may indicate this. A professional will be required to examine 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 your home. If this is happening the structural integrity of windows' sash could be at risk, and they will likely need to be replaced with an alternative option.

A common issue with repairing sashes is when the sash becomes stuck in the frame. This could be caused by a snapped cord or a problem with sash rattles. If it is the latter, then a bit of gentle pressure can help the window to be opened again - or alternatively, the ratchets need to be reset.

This issue can be fixed by taking the sash off and cleaning the tracks. After the tracks have been cleaned take off any security fittings that could be present. Lastly, carefully taking off the sash cords and chains will allow the sash to be removed. The staff bead can be sealed using a draught-proof seal that will reduce the risk of draughts. This will also improve the finish of paint. Decorators caulk can be used to fill the gap between the sash's box and the sash. This will improve the efficiency of the sash and reduce the risk of draughts.
