Sash Window Repair

Sash windows can go out of balance and crack. Pam is on the lookout on the internet for salvaged wavy glasses, and keeps an eye out for discarded metal sashweights. She then searches for replacements in the form of washers or nuts to help balance her window repairs.

Pam will lay each pan by placing a rope of glazing material into the rabbet groove, or pocket around the opening. This helps cut drafts and costly heat loss.

Sticking Sashes

If your double-hung windows get stuck in the middle, it's an absolute nightmare. You'll lose sight when they squeak during a storm. A window that is too loose can let in external noise and air which can increase your energy costs. Both of these scenarios are not ideal however they can be corrected by using the right tools and perseverance.

Paint can get splattered on the channels of old weighted window tracks, causing them to block. The majority of these issues can be resolved by cleaning and oiling the tracks.

Take the caulking off of the space between the window stop (the one on the inside) and the frame of the window. Scrape off any paint that has built up. Use a sharp knife and put sheets of plastic as well as a dust-collecting vacuum cleaner below the surface to collect any paint dust or chips.

Clean the tracks using a dry cloth, and apply a silicone lubricant to ensure better gliding. This lubricant is available at many home improvement stores or online. You can test it by moving the sash either upwards or downwards.

If it continues to stop the sash cable could be faulty. Check to see whether the cord is catching or hanging from the sash, or has snapped off completely. If this is the case, you'll need to replace the window's cord.

A pin that holds the rail in place may have been ripped out. It isn't easy to fix and you'll require the help of a professional most of the time.

Use a wood hardener if the wood is swollen and warped but there's no pin. The liquid is quick drying and can help restore damaged wood. It's not necessary to remove your sash windows in order to repair them. After you've used it you'll be able remove the two sashes by placing a piece of wood on the top of the corner where they meet, and tapping it lightly using a hammer.

Draughts

Draughts are a major problem for windows with sash windows that are old particularly in winter months. They are usually caused by decaying wood, cracked putty, or worn sash cords. This can allow cold air to enter the window, making it more difficult to heat your home. There are some things you can do to prevent draughts from entering your windows with sash, for example, filling any gaps with expanding foam or using strips to block draughts that you can purchase at many hardware stores. These can be effective, but they will need to be replaced from time to time because the foam expands and wears away with use.

A more permanent solution is Gapseal, a spongy rubbbery seal that you can cut to size and put into the gaps between the sash window frame. It can be used by itself or in conjunction with adhesive strips at the top and bottom. This is a bit costly and must be reapplied throughout the time of your windows' lifespan, but it is a long-term solution and is easy to take off in the event that you want to open the window.

Another popular DIY method of draughtproofing is to use cling film that is scrunched up and pushed into all the gaps around your window. This is a reliable draught blocker, but the drawback is that it could stop sash movement completely and could pose a fire hazard. The sash must be removed in order to reopen the window, and the clingfilm will need to be applied every time the sash is closed.

A better option is to have your windows draught-proofed as part of a complete refurbishment service. This can include the installation of new sash strings staff beads and parting beads in addition to the lubrication and rebalancing the weights, as well as the lubrication and rebalancing the pulley wheel. It may also include staining or painting the frames and the sashes. This will help restore the sash's function and improve its energy efficiency, in addition to fixing any minor wood imperfections. It is much less disruptive than replacing windows altogether and will significantly reduce draughts and improve your home's thermal efficiency.

Decay

The good thing is that your frames for sash windows aren't beyond repair if they have been damaged or deteriorated. The frames of these windows are generally constructed from high-quality timber. With the right restoration, they can be restored to give you the best performance for a long time. Regular inspections are crucial in ensuring that the wood is adequately ventilated. This will help prevent moisture build-up that can cause wood decay.

Most of the problems that you'll encounter with sash windows are easily visible on a close inspection, but some are more difficult to detect. Wood decay is particularly difficult to treat, since the fungus consumes the wood. While it is possible to repair rotten timber however the best method to prevent further decay is to keep the timber dry.

First, take off any paint from the hardware. The bottom rail and the meeting rail could require removal from the frame (depending on the location of your sash). The next step is to take off the "pocket covers" that are pieces of wood that are located on the sides of the frame that are low down that provide access to the weights (the partsing beads run along 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 are removed, you can start chiseling out any wood rot and apply a high-quality water-resistant filler. After the filler has dried, the primer must be applied to protect against further decay.

It is a good idea to check inside the window for sashweights to ensure they are in balance. They should not be displaced, or pulling one side harder than the other. The sash could slide off the track if it is not properly balanced. This could cause the frame to break or even be damaged. The sash's weights can be replaced with new ones or a new balancing mechanism could be fitted to stop the sashes from swinging to the wrong side of the window frame.

Poor Security

Sash windows are vulnerable to damage and wear due to weather conditions over time. This can lead to the decay of timber, and requires replacement. Water marks on the window or on a softened frame could be a sign of decaying wood. A professional consultation is required to evaluate the situation and recommend any required sash window repair (published on Edid) work.

Similarly, over time the bottom rails can be damaged. The sill may show water marks or a window that is soft to the touch can indicate this. A professional is required to evaluate the situation and recommend any needed resealing of sash windows components or replacement.

Double and triple-glazed sash windows do an amazing job at keeping noise pollution out of your home, but it can be a major cause of concern when they start to let it back in. If this is happening, the structural integrity of windows could be at risk and it is likely to need to be replaced with a different option.

A common sash window repair problem is when the sash gets stuck in the frame. It could be due to a snapped cord or problems with sash ratchets. If the issue is related to the sash the ratchets, some gentle persuasion is often the best solution.

This problem can be resolved by removing the sash and cleaning the tracks. Once the tracks are clean, removing any security fittings that may be present, and then removal of the sash cords as well as chains will allow the sash to be removed. A draught seal could be put on the staff bead to reduce the appearance of the paint finish. The gap between the box and the sash can be filled with decorators caulk to enhance the operation of the sash and lessen the risk of draughts.
