Sashes that have been damaged

If your sash windows have been damaged or leaky it is necessary to go beyond repair the surface. Doing a thorough repair can save you money in the long run, particularly when you live in an older home that is not well-insulated.

If the sash doesn't fit well within the frame it may be difficult to open or close the window. This could result in rattling sounds and let drafts in your home.

Broken Sash Cords

Some old double glazed timber sash windows-hung sashes have metal or cotton cords that support the weights used to lift and lower the sashes. Over time, the cords can break, making it impossible to lift or keep the sash up. To fix this, follow these steps:

Remove the frame from the sash and pull it to the right until it is completely open. Pull the cord from the bottom of the sash, then cut it and take out any nails sticking out from the end. Pull the nail free with needle-nose pliers, then insert it back into the side channel. Tuck the cord knot into the hole, and secure it using the nail set.

Install the staff beads and install the sash. Be sure to leave plenty of for the cords to ensure proper operation. Reinstall the balances and counterweights. To minimize draughts small amount of decorators caulk may be applied between the bead of the staff and the box.

After the frame and sash are fully repaired, bed them in glazing putty. Glazing putty is usually made of linseed oil and chalk. Mix with enough chalk to make the putty workable and not stick to your fingers. Let the putty dry completely before reinstalling the sash, or painting the frame.

Broken sash cords

To balance and support the sashes in old double-hung windows (two sashes) cotton cords or chains are attached to the counterweights. Over time, the cords can break which prevents the sashes from opening or closing, making it difficult to lower or raise the window. The sash cords can be replaced in less than a few hours.

Begin by removing the staff bead, which separates the upper and lower sashes. A nail is usually driven through the knot, and then into the sash's casingor paint buildup, or sash cords that have become rotted. There are many easy and cost-effective ways to fix these issues and keep your windows operating properly.

Disassembling an old sash is the initial step to repair it. Remove the sash, and frame, and check whether all parts are in good shape. Sand the wood to make it appear better and stop drafts. A small amount of silicone or wax can help the sash move more easily. If the sash is still stuck, use a utility knife to cut through any paint layers and free it. The addition of a new set tilt pins could also enhance the window's performance.

Weights are pushed across pulleys in order to balance the weight of a sash window. The weights, typically made of cast iron, are accessible via an access panel or pocket within the lining of the box. To prevent the weights from falling down, an dividing strip is hung within the frame to ensure that they don't collide.

It isn't easy to access these weights, as the upper sash can be sealed with paint and then put in place. If you're patient and careful, you can remove the sash by using a pair of bar clamps, reversed to break apart, allowing it out of its groove in the rails that meet. It may take a bit of jiggling and tapping to get it out but once you've got removed it, make sure to check the sash cord and replace window sashes it with a new rope (not cotton) If you need to.

While you're at it you could also change the sash balance to make the window easier to open and close. It's not as difficult as you think to change the double-hung balance on a window. You can do it yourself if have the right tools and replacement kit.

Rotten sill

Over time, old timbers become damaged and even the best-maintained windows made of sash will begin to exhibit signs of decay. If the rot only affects the sill of the window, it could be possible to repair it. If the rot has spread to the frame and even into the interior, and damaged structural elements, it may be time to replace the window.

It is crucial to replace a damaged window sill before it causes damage to the window. The first step is to remove the sill plate that was previously installed and studs. If the studs are load bearing they may require you to put in temporary supports. After taking off the sill, clean any remaining paint on the sill plate. When the sill is clean then replace it with a new board and attach it to the studs.

A sill that is rotten is not just unsightly but can also lead to expensive repairs in the near future. For instance, it could cause the sash to shift which is difficult to spot and could lead to cracks or broken glass pane. A rotten sill can allow water to get into the wall, causing mold.

Replacing a sill that is rotten is not as hard as it sounds. It is essential to keep the window well-maintained to avoid rot. Therefore, you must regularly clean the window tracks and sashes in order to keep them free from dirt and other debris. Apply a sealant to the window frames to keep them dry. You can also use a humidifier to regulate the moisture in your home. This will stop wooden sashes from forming or swelling.

Sticky sashes are a frequent issue with windows made of sash. This issue can be fixed by applying a small amount silicone or wax to the tracks of your windows. This will allow them to slide more easily. If the sashes have become stuck due to the buildup of paint, you can use an utility knife to slice through the paint layers and remove the sashes.

Another way to solve a sticking sash is to reinstall the parting bead. If the sash is still stuck, you can try draught-proofing it. This involves putting a rubber strip between the frame and sash, which reduces air flow and enhances the acoustic performance of the window.
