Sash Window Repair

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

Pam will bed each pan by putting a rope of glazing material into the rabbet groove, or pocket around the opening. This reduces drafts and prevent costly heat loss.

Sticking Sashes

If your double-hung windows get stuck, it's an absolute nightmare. They'll shake in the event of an icy storm and you'll lose view. On the other hand, a window that's too loose will allow external air and noise in and your energy costs can increase. Neither scenario is ideal, but both could be solved with the proper tools and determination.

One of the most common issues with windows with weighted sash is that paint may get sucked into the channels they slide on, causing them jam. Luckily, most issues with this can be solved by cleaning and lubricating 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 built up. Make use of a sharp knife, and put plastic sheets and a dust-collecting vacuum cleaner below the surface to collect any paint dust or chips.

Then, wipe the tracks with a dry, clean cloth and apply a silicone lubricant to ensure more smooth glide. It is available in most home improvement stores, or on the internet. Then, move the sash upwards or down to test it.

If it continues to jam, the sash cable may be defective. Examine the sash cord to determine if the cord is caught or hanging up in the sash, or has snapped completely. If this is the situation, you'll need to re-cord the window.

Another possible cause of an obstruction is that a pin that holds the rail in place has fallen out. This can be tricky to fix, and you'll need to contact a professional in most cases.

If a pin hasn't fallen out but the wood has become swollen or warped it's recommended to use a wood hardener on it. This liquid dries quickly and can restore damaged wood. You won't have to remove your sash windows to repair them. After using it, you should be able to pry the two sashes apart by placing a block of wood on the top of the corner where they meet and tapping it lightly with the tool.

Draughts

Draughts can be a problem with old sash window, especially during the winter. Often caused by rotten timbers or cracked putty, worn weights for sash or sash cords that aren't balanced that let cold air seep into the upvc window repair and make it difficult to keep your home warm. You can prevent draughts by filling gaps with expanding foam or by using draught-proof strips that are that are available in most hardware stores. They can be very effective, but they'll need to be replaced from time to time because the foam expands and gets worn away with time.

Gapseal is a more permanent solution. It's a spongy, rubbly seal that can be cut and push in the gaps between the window frames of the sash. It can be applied on its own or with adhesive strips on the top and bottom of the frame. This option is costly and you'll need to reapply it over the life of your window. But, it's a long-term fix and is easy to remove.

Cling film can also be used to stop draughts. Simply scrunch it and push it into the gaps that surround your window. This is a great draught-stopper however it could also hinder the sash's movement and possibly cause fire. Additionally, the sash will need to be removed for you to open the window again and the cling film has to be reapplied each time you close the sash.

An alternative that is less expensive is to have your windows draught-proofed as part of a complete refurbishment service. This could include new sash cords, staff beads, parting beads, lubrication of the pulley wheels and rebalancing the weights, and painting or staining the frames and sashes. This will help restore the function of the sash, and increase its energy efficiency, while also fixing any minor wood defects. It's less disruptive than replacing the windows altogether and will significantly reduce draughts as well as improve your home's thermal efficiency.

Decay

The good news is that your frames for sash windows aren't damaged beyond repair even if they have been damaged or deteriorated. The frames of these windows are typically made of high-quality timber. With the right restoration, they can be restored to provide high performance for many more years. The key is to conduct regular inspections and ensuring that the wood is properly ventilated to stop moisture accumulation which can lead to wood rot.

Most of the problems that you'll encounter with sash windows are readily apparent on close visual inspection, but some are more difficult to detect. Wood decay is difficult to treat, since the fungus consumes the wood. It is possible to repair damaged sections of timber but the best way to prevent future rot is to make sure the timber is kept dry.

First, remove any paint from the hardware. It may be necessary to remove the bottom rail from the frame and also the meeting rail (this will depend on the position of the sash). The "pocket covers" are tiny pieces of wood placed on the frame's side that permit access to the weights, should be removed. These are often fixed by nailing them in place and then securing them with paint, so you'll likely require an instrument to break 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. After the filler has dried, the primer must be applied to guard against further decay.

It is a smart idea to examine inside the window the sashweights to make sure they are properly balanced. They should not be displaced, or pulling one side more strongly than the other. The sash may be thrown off its track if they aren't properly balanced. This could cause the frame to break or become damaged. You can replace the sashweights with new ones or install an updated balancing system to prevent the sash from moving the wrong direction.

Poor Security

As time passes sash windows become exposed to the elements and prone to deterioration from weather and general wear. This can cause decay of the timber, which requires replacement. Wood decay can be detected by water marks on the window, or by the frame becoming soft to the touch. A professional consultation will be required to evaluate the situation and recommend any necessary sash window repair work.

Similarly, over time the rails on the bottom can become damaged. This is evident by the presence of water marks on the sill or by the window becoming soft to the touch. A professional will be required to assess the situation, and recommend any necessary replacement of the sash window's seal or replacement.

It is a major concern when triple or double glazed windows start to let noise pollution back into your home. If this happens, the structural integrity of windows could be at risk, and they will most likely require to be replaced with an alternative option.

A typical sash window repair problem is that the sash becomes stuck in the frame. This can be caused by the sash cord being snapped, or it could be a sign of an issue with the sash's or ratchets. If the problem is with the sash the ratchets, some 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 carefully remove the sash cords or chains. The staff bead can be sealed with an draught-proof seal in order to minimize draughts. This can also improve the finish of the paint. Decorators caulk can be used to fill the gap between the box of the sash and the sash. This will improve the efficiency of the sash and also reduce the possibility of draughts.
