Sash Window Repair

Sash windows could be out of balance or even break. Pam is on the lookout on the internet for salvaged wavy glasses and keeps an eye open for discarded metal sashweights. She then searches for replacements, such as washers or nuts, to ensure that her window is balanced.

Pam puts each pane in with a rope of glazing compound she puts into the rabbet groove, or pocket, which is located around the opening. This prevents drafts and costly heat loss.

Sticking Sashes

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

One of the most common issues with windows with weighted sash is that paint can accumulate in the channels that they slide over, causing them jam. Fortunately, most issues related to this can be solved through cleaning and lubricating the tracks.

Remove the old caulking from the space between the window stop (the one on the inside) and the frame of the window. Then scrape away any paint that has accumulated. Make use of a sharp knife and put plastic sheets and dust-collecting vacuum cleaners below the surface to catch any paint dust or chips.

Clean the tracks using a dry cloth, and apply a silicone-based lubricant to aid in their smoother movement. The lubricant can be found at most home improvement shops or on the internet. You can test it by dragging the sash upwards or downwards.

If it continues to jam the sash cable could be defective. Check to see whether the cord is catching or hanging up in the sash, or if it has snapped off completely. If this is the case, you'll need to reconnect the window.

Another possible cause of the jam could be the pin that holds the meeting rail in place has slipped away. This isn't easy to fix, and you'll need to contact a professional in most instances.

If a pin hasn't fallen out, but the wood has become warped or swollen it's a good idea use a wood hardener on it. The liquid is quick drying and can repair damaged wood. It's not necessary to remove the windows on your sash to repair them. After using it, you can pry apart the two sashes by placing a piece wood on the lower corner of the window where they meet.

Draughts

Draughts are a major problem for windows with sash windows that are old particularly during winter months. They are often caused by rotten wood or cracked putty, worn weights, or sash cords that are not balanced that allow cold air to seep in around the window, making it difficult to keep your home warm. You can prevent drafts by filling in gaps with expanding foam, or by utilizing draught-proofing strips that are that are available in most hardware stores. They're effective however you'll require replacing them regularly as the foam expands with usage.

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

Another popular DIY draught proofing solution is to use cling film scrunched up and placed into the gaps around your window. This is a great way to stop draughts however it could also hinder the sash's movement and cause a fire. Additionally the sash will have to be removed to open the window again and the cling film has to be applied every time you close the sash.

A more cost-effective solution is to have your window sash professionally draughtproofed as part of a complete refurbishment service. This could include new sash cords as well as parting beads, staff beads, lubrication of the pulley wheels and rebalancing of the weights, and staining or painting the frames and sashes. This can restore the sash to its original function and increase its energy efficiency and correct any minor flaws in the timber. It's less disruptive than removing windows and will reduce drafts, enhance the thermal efficiency and dramatically reduce the cost.

Decay

The good news is that your sash window frames are not in need of repair if they've been damaged or degraded. The wood used in the frames of these windows is typically of high-quality and, with the right restoration, can be revived to provide a high level of performance for many years. The key is regularly checking the frames and ensuring that the timber is properly ventilated to avoid moisture accumulation which can lead to wood decay.

The majority of problems with sash window are easily visible, but others are more difficult to identify. Wood decay is particularly difficult to fix, as the fungus consumes the wood. While it is possible to repair damaged timber, the best way to avoid future decay is to keep the timber dry.

First, clean any paint from the hardware. It may be necessary to remove the bottom rail from the frame and the rail for meeting (this will depend on the location of the sash). The "pocket covers", which are small pieces of wood on the frame's side that permit access to the weights will need to be removed. You may need to use a sharp knife to take them if they are fixed or painted. Once the pockets have been removed, you can begin chiseling out any wood rot and apply an excellent, water-resistant filler. After the filler is dry, a primer coat should be applied to stop further decay.

It is a smart idea to examine inside the window the weights of the sash to ensure that they are balanced. They shouldn't be displaced or pulled one side more than the other. If they are not balanced the sash can fall off its track and could cause damage to the frame. You can replace the sashweights by new ones or install a new balancing system to stop the sash from moving the wrong direction.

Poor Security

As time passes sash windows become exposed to the elements, and are prone to damage from weather and general wear. Over time, this can result in wood decay that requires to be replaced, costly repair that needs to be dealt with as soon as is possible. Water marks under the window or a softened frame could be a sign of decaying wood. It is essential to speak with a professional to assess the situation and determine if sash window repairs are necessary.

As time passes the rails at the bottom can also be damaged. The sill may show water marks or a window which is soft to the touch can be an indication of this. A professional consultation may be required to determine the situation and recommend any repair or replacement of the sash window's components.

It is a major concern when triple and double glazing windows begin to let noise pollution back into the house. If this occurs the structural integrity of the window could be at stake and the sash window will require replacement.

One common sash window repair problem is the sash becoming stuck in the frame. It could be due to the cord snapping or a problem with sash ratchets. If the problem is with the sash's rats, a bit of gentle pressure is usually enough.

This problem can be resolved by removing the sash and cleaning the tracks. After cleaning the tracks, remove any security fittings, and then remove the chains or sash cords. The staff bead can be sealed using an draught-proof seal in order to minimize the risk of draughts. This can also improve the finish of the paint. 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 draughts.
