Sash windows can get out of balance and crack. Pam scours the web for salvaged, wavy glass repairs and keep an eye out for discarded, metal sash weights. She then seeks replacements, such as washers or nuts to help balance her window.
Pam covers each pan with a rope of glazing compound she puts into the rabbet groove, or pocket, that is around the opening. This reduces drafts and expensive heat loss.
Sticking Sashes
When your double-hung window gets stuck in the middle, it's a nightmare. They'll shake during a storm and you'll lose view. On the other side, a window that's too loose will allow external air and noise through and your energy bills can increase. Both of these scenarios are not ideal but they can be corrected with the proper tools and persistence.
Paint can accumulate on the channels of the old weighted sash window tracks, causing them to jam. Most of these problems can be resolved by cleaning and oiling the tracks.
Remove the old caulking from the space between the window stop (the one on the inside) and the frame of the window. Scrape away any accumulated paint. Use a sharp knife and put sheets of plastic and a dust-collecting vacuum cleaner below the surface to catch any paint dust or chips.
Clean the tracks using a dry cloth, and apply a silicone lubricant for more smooth glide. The lubricant can be found at most home improvement shops or online. You can test it by moving the sash either upwards or downwards.
If it is still jamming it could be due to an issue with the sash cord. Check to see whether the cord is caught or hanging up in the sash, or has snapped completely. You'll have to re-cord your window if this is the situation.
A pin that holds the rail in place might have fallen out. It isn't easy to fix and you will need to call in a professional the majority often.
If a pin hasn't fallen out, but the wood has gotten warped or swollen it's a good idea to use a wood softener on it. It's a quick drying liquid that can help restore damaged wood, so you'll be able to repair your window without having to remove it completely. After you've used it you should be able to remove the two sashes by placing a block of wood on top of the bottom corner where they meet, and tapping it lightly using an Hammer.
Draughts
Draughts can cause problems with sash windows that are old particularly in winter. They are often caused by rotten wood or cracked putty, worn weights, or sash cords that are not balanced which can let cold air seep in around the window and make it difficult to keep your home warm. There are several options you can take to help prevent draughts in your windows with sash, for example, filling any gaps with expanding foam or strips to prevent draughts. These can purchase from most hardware stores. They're effective, but they will need to replace them periodically as the foam expands with usage.
A more permanent option is Gapseal which is a sponge-like seal that you cut to the size you require and then insert into the gaps between the sash window frame. It can be applied on its own or in conjunction with adhesive strips on the top and bottom of the frame. This is a bit costly and must be reapplied over the duration of your window's life, but it can provide an option for the long term and is easy to remove if you want to open the window.
Another popular DIY method of draughtproofing is to use cling film that is scrunched up and placed into the gaps around your window. This is a great draught stopper, but the drawback is that it could block sash travel completely and pose an hazard to fire. The sash needs to be removed to reopen the window and the clingfilm will need to be applied every time the sash is closed.
A more cost-effective solution is to have your sash windows professionally draught proofed as part of a comprehensive refurbishment service. This can include the installation of new sash strings, parting beads and staff beads in addition to the lubrication and rebalancing the weights and the fluidization and rebalancing of the pulley wheel. It may also include staining or painting of the frames and sashes. This will restore the sash to its original function, improve its energy efficiency, and repair any minor imperfections in the wood. It's less disruptive than replacing windows altogether and will significantly reduce drafts and enhance the thermal efficiency of your home.
Decay
The good news is that your sash window frames are not in need of repair door if they've been damaged or deteriorated. The timber used in the frames of these windows is usually of very high-quality and, with the right restoration, can be restored to provide the best performance for many years. Regular inspections are key, as is ensuring the wood is properly ventilated. This will stop moisture build-up that can lead to wood rot.
Most of the problems that you'll encounter with sash windows are evident upon close examination, however certain issues are more difficult to identify. Particularly, wood decay is a very difficult problem to fix because fungus consumes the wood. It is possible to repair double glazing window rotten sections of timber, however, the best method to avoid further decay is to ensure that the timber is dry.
The first thing to do is to remove any paint off the hardware. The bottom rail and the meeting rail could require removal from the frame (depending on the location of your sash). You will then need to remove the "pocket covers" which are pieces of wood in the side of the frame 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 take them if they are fixed or painted. 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 is dry, a primer coat should be applied to stop further decay.
It is recommended to inspect the sash's weights inside the window as well to ensure that they are in balance and not pulling one side more than the other. If they aren't balanced, the sash is liable to fall off its track and cause damage to the frame. You can replace the sashweights using new ones, or install an updated balancing system to prevent the sash from swinging the wrong direction.
Poor Security
Over time sash windows become exposed to the elements, and are prone to deterioration due to weather and general wear. This can cause decay of the timber, which requires replacement. Water marks on the window repairman or a frame that is soft could indicate decay of the wood. It is essential to speak with an expert to evaluate the situation, and determine if sash window repairs are necessary.
Additionally, with time, the rails at the bottom may become damaged. The sill may show water marks, or a window that is soft to the touch may indicate this. A professional is required to assess the situation, and recommend any resealing of sash windows components or replacement.
Double and triple-glazed sash windows do an amazing job at keeping noise pollution from entering your home, so it can be a major cause of concern when they start to let it in. If this occurs, the structural integrity may be at risk and the sash window may need to be replaced.
A common issue with repairing sashes is when the sash becomes stuck in the frame. It could be due to the cord snapping or a problem with sash the ratchets. If it's the latter scenario, a little gentle pressure can help the window to be opened to reopen. Alternatively, the ratchets will need to be reset.
Removal of the sash from the frame and removing the tracks of dirt or dust can assist in resolving this problem. After cleaning the tracks, take off any security fittings, and then remove the sash cords or chains. A draught seal could be applied around the staff bead to decrease draughts and enhance the appearance of the paint finish. The gap between the box and sash can then be filled with decorators caulk to improve the operation of the sash and decrease draughts.
