Sash Window Repair

Sash windows can go out of balance and break. Pam scours the web for salvaged Wavy glass, wavy glass, and is always looking for the sash weights that are discarded, made of metal. She then searches for replacements in the form of washers or nuts to balance her window.

Pam will set each pan by putting a rope of glazing material into the rabbet groove, or pocket around the opening. This helps to reduce drafts and costly heat loss.

Sashes that stick Sashes

It's a nightmare when double-hung windows get stuck. You'll lose your view in the event that they shake during a storm. A window that's too loose may allow in air and noise which could increase your energy bills. Neither scenario is ideal, but both could be solved with the right tools and a little determination.

Paint can build up on the channels of the old weighted sash window tracks, causing them to become jammed. Most of these problems can be solved by cleaning and oiling the tracks.

Start by removing the old caulking between the window stop (the one inside) and the window frame. Scrape off any paint that has accumulated. Make sure you make use of a sharp blade and set up sheets of plastic and a vacuum cleaner right below to catch any paint dust and chips.

Clean the tracks with a dry cloth, and apply an oil based on silicone to help them slide better. It is available at the majority of home improvement stores or online. You can test it by dragging the sash upwards or downwards.

If it continues to block it could be faulty. Check to see whether the cord is stuck or hanging in the sash or if it's snapped. If this is the case, you'll need to re-cord the window repairs.

Another possible cause of the jam could be the pin that holds the rail in place has fallen out. It isn't easy to fix and you will have to call a professional the majority often.

If a pin doesn't fall out, but the wood has become warped or swollen, it's a good idea to use a wood hardener on it. This liquid dries quickly and can repair damaged wood. It's not necessary to take out the windows on your sash to repair them. After using it, you'll be able to break the two sashes by placing a piece of wood on the bottom corner where they meet and tapping it lightly using an Hammer.

Draughts

Draughts can be a major issue for old sash windows, especially in the winter months. Often caused by rotten timbers 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 stop draughts by filling gaps with expanding foam, or by using draught-proof strips that are available at most hardware shops. They are efficient however, you will need to replace them periodically because 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 used on its own or with adhesive strips at the top and bottom. This is costly and you'll have to reapply it throughout the life of your window. However, it's a long-term fix and is simple to remove.

Cling film can also be used to stop drafts. Simply scrunch it up and then insert it into all the gaps around your window. This is a great draught-stopper, but it can also hinder the movement of the sash and possibly cause fire. Furthermore the sash will have to be removed to open the window again and the cling film will need to be reapplied each time you close the sash.

A more cost-effective solution is to have your windows draught-proofed as part of a comprehensive refurbishment service. This can include new sash cords and staff beads, parting beads, lubrication for the pulley wheels and rebalancing of the weights, as well as painting or staining the frames and sashes. This can help to restore the function of the sash, and increase its energy efficiency, in addition to fixing any minor wood defects. It is less disruptive than removing the windows and will reduce draughts, improve the thermal performance, and drastically reduce costs.

Decay

The good thing is that your sash window frames are not beyond repair if they have been damaged or decayed. The wood used in the frames of these windows is typically of high-quality and, with proper restoration, they can be restored to offer an excellent level of performance for many years. Regular inspections are essential in ensuring that the wood is adequately ventilated. This will prevent the build-up of moisture that could lead to wood rot.

The majority of problems with sash windows are easily apparent, however some are more difficult to spot. Particularly, wood decay is a difficult issue to address because fungus eats away at the wood. While it is possible repair damaged timber but the best way to avoid future rot is by keeping the wood dry.

First, clean any paint from the hardware. The bottom rail and the connecting rail could have to be removed from the frame (depending on the position of your sash). You will then need to take off the "pocket covers" that are pieces of wood on the side of the frame low down that allow access to the weights (the parting beads run through the middle of them). They can be fixed by nailing them in place and then securing them with paint, so you will probably need to use a knife to get them off. Once the pockets are gone, you can begin to chisel out any wood rot, and then apply a high-quality water-resistant wood filler. Once the filler is dry, it is recommended that a coat of primer be applied to guard against further decay.

It is a good idea to inspect inside the window for sashweights to ensure they are balanced. They shouldn't be in the wrong alignment, or pulling one side more strongly than the other. The sash could fall off its track if they are not properly balanced. This could cause the frame to fall or become damaged. You can replace the sashweights using new ones, or put in a new balancing system to stop the sash from swinging the wrong direction.

Poor Security

As time passes, sash windows can become exposed to the elements and prone to damage from weather and general wear. This can cause decay of timber, which requires replacement. Water marks under the window or on a softened frame could be a sign of decaying wood. It is crucial to speak with an expert to evaluate the situation and determine if any repairs to the window sash are needed.

In time the rails on the bottom may also be damaged. This is evident by the presence of water marks on the sill or by the window becoming soft to the touch. A professional consultation will also be required to assess the situation and recommend any needed replacement or resealing of the sash window's components.

It can be a real concern when double and triple windows are glazed and start to allow noise pollution back into your home. If this happens the structural integrity of the sash windows may be at risk and it will likely need to be replaced with a different option.

A typical problem with repairing sash windows is that the sash becomes stuck in the frame. It could be caused by the sash cord being snapped, or it could be an indication of an issue with the sash's or ratchets. If the problem is related to the sash the ratchets, some gentle persuasion will usually work.

This issue can be solved by removing the sash and cleaning the tracks. After the tracks have been cleaned take off any security fittings that might be present. Lastly, carefully removal of the sash cords as well as chains will allow the sash to be removed. A draught seal can then be placed around the staff bead to decrease draughts and enhance the appearance of the paint finish. The gap between the box and sash could be filled with decorators caulk to improve the operation of the sash and decrease the risk of draughts.
