Pam beds each pane 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 prevent costly heat loss.

Sticking Sashes

If your double-hung windows get stuck and shatters, it's a nightmare. You'll lose sight when they squeak during a thunderstorm. On the other the other hand, windows that are too loose will let external air and noise in and your energy bills may increase. Both scenarios are not ideal, but both could be addressed with the appropriate tools and determination.


Paint can accumulate on the channels of the old weighted sash window tracks, which can cause them to become jammed. Fortunately, most issues related to this can be resolved by cleaning and lubricating the tracks.

Start by removing the caulking that was between the window stop (the internal one) and the window frame. Scrape away any paint that has accumulated. Use a sharp knife and place sheets of plastic and dust-collecting vacuum cleaners below the surface to catch any paint dust or chips.

You can then clean the tracks using a dry cloth, and then apply an oil based on silicone to help them slide better. You can purchase this in most home improvement stores, or on the internet. upvc window repairs can test it by dragging the sash upwards or downwards.

If it continues to stop, the sash cable may be defective. Examine the sash cord to determine if the cord is caught or hanging from the sash, or if it has snapped completely. If this is the situation, you'll need to replace the window's cord.

Another possible reason for the jam could be that a pin that holds the rail in place has slipped out. It isn't easy to fix and you will need to call in a professional most of the time.

If a pin doesn't fall out, but the wood has gotten warped or swollen, it's a good idea to apply a wood hardener to it. This liquid will dry quickly and can restore damaged wood. You won't have remove the windows on your sash to repair them. After you've used it, you can pull the two sashes apart by placing a piece of wood in the bottom corner of the window where they meet.

They are often caused by rotten wood, cracked putty, worn weights, or sash cords that are not balanced, they can let cold air seep in around the window, making it difficult to keep your home warm. You can stop draughts by filling gaps with expanding foam or by using draught-proof strips that are available at most hardware shops. These are effective however, you will require replacement periodically as the foam expands with usage.

A alternative that is more durable is Gapseal which is a spongy rubbbery seal that can be cut to the desired size and then insert into the gaps between the window frames of your sash. It can be applied by itself or with adhesive strips on the top and bottom of the frame. This option is costly and you will need to apply it again over the life of your window. However, it is an effective long-term fix and easy to remove.

Cling film can also be used to stop drafts. Simply roll it up and push it into all the gaps that surround your window. This is a reliable draught stopper but the downside is that it can block sash travel completely and pose risky for fire. The sash must be removed to open the window and the clingfilm will need reapplied every time the sash is closed.

As part of a general overhaul, you can have your sash window professionally draught-proofed. This can include new sash cords as well as staff beads, parting beads, lubrication of pulley wheels and rebalancing of the weights, and painting or staining the frames and sashes. This could restore the sash to its original purpose and increase its energy efficiency and correct any minor flaws in the wood. It is less disruptive than removing windows and will reduce draughts, improve the thermal efficiency and dramatically 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 timber used in the frames of these windows is typically of a very high quality and, with the right restoration, can be restored to provide an excellent level of performance for many years.

The first step is to strip any paint from the hardware. The bottom rail and the meeting rail might need to be removed from the frame (depending on the location of your sash). The "pocket covers" are tiny pieces of wood on the frame's side that permit access to the weights must be removed. These are often nailed in place and stuck with paint, so you will likely need to use an instrument to break them off. Once the pockets have been removed, you can start chiseling out any wood rot and apply an extremely high-quality, water-resistant filler. Once the filler is dry, the primer must be applied to guard against further decay.

It is a good idea to examine inside the window for sashweights to make sure they are balanced. They should not be displaced or pulled one side harder than the other. If they are not balanced the sash can drop off its track and could cause damage to the frame. The sash's weights can be replaced with new ones or a new balance mechanism can be fitted to stop the sashes from swinging towards the opposite side of the window frame.

Poor Security

Sash windows are vulnerable to wear and tear from weather and wear over time. Over time, this can cause wood decay, which in turn will need to be replaced, a costly repair that needs to be addressed as quickly as is possible.

If it's the latter the gentle persuasion can usually help the window to open to reopen. Alternatively, the ratchets will need to be reset.

Removing the sash from the frame and cleaning the tracks of dirt or dust will often assist in resolving this issue. After cleaning the tracks, remove any security fittings, and then remove the chains or sash cords. A draught seal can then be applied around the staff bead to reduce draughts and enhance the appearance of the paint finish. The gap between the box and the sash can be filled with decorators caulk to improve sash operation and reduce the risk of draughts.
