Sash Window Repair

Sash windows add a touch class to any home. However, they can also be drafty and difficult to clean due to age or wear. Sash window repair is a great method to improve functionality while maintaining the original beauty of your windows.

The first step in repairing sash windows is to remove "pocket covers". These are bits of wood, tucked away on the frame, which allow access to the weights.

Sashes damaged by abrasions

If your sash window has been damaged or leaks, you will need to do more that just patch the surface. Performing a more comprehensive repair job will save you money in the long run, particularly when you live in an older home that is not well-insulated. Here are some typical sash window problems and how to fix them:

Sticking Issues

It can be difficult to shut or open the window when the sash doesn't fit properly into the frame. This can cause rattling sounds and let drafts in your home.

To fix this, use an utility knife to score and then cut away the paint line from the inside side of your sash. Be careful not to scratch the wood. Then, you'll need to apply a sash lubricant that will help it move smoothly.

Broken Sash Cords

Some double-hung sashes that are old have metal or cotton cords supporting the weights used lift and lower the sashes. Over time, the cords can break, rendering it impossible to lift or hold the sash in place. Follow these steps to repair it:

Remove the frame from the sash and pull it to the right until it's completely open. Cut the cord in the middle of the sash, and then remove any nails sticking out from the end. Take the nail off using needle-nose pliers, then insert it back into the side channel. Incorporate the cord knot into the hole and secure it with a nail set.

Install the sash again and add the staff beads. Make sure you leave enough space on the cords to ensure proper operation. Reinstall the balances and counterweights. Decorators caulk is an excellent way to prevent draughts. Apply a small amount between the staff bead box.

When the frame and sash are fully repaired, bed them in glazing putty. Glazing putty can be made by mixing chalk and linseed. Mix in enough chalk to make the putty pliable and not stick to your fingers. Allow the putty to dry completely before applying the sash back and painting the frame.

Broken sash cords

To support and balance the sashes in old double-hung windows (two sashes) cotton cords or chains are attached to the counterweights. As time passes, the cords can break which prevents the sashes from opening or closing and makes it difficult to lower or raise the window. Repairing the sash cords is a simple home fix that will solve the issue within less than a half hour.

Take off the staff bead, which separates the upper from lower sashes. A nail is typically driven through the knot and then into the sash's casing to secure the bead in place however, you should be in a position to remove it using needle-nose pliers. Remove any rusty nail from the stop beads, and then clean the caulk and old cord residue and paint around the groove of the sash.

To open the Casement Window Sash, pull on one of the cords running through the sliding sash windows to lift it up. When you've pulled it as far as it will be make a mark on the cord using a pencil and cut it to length using an utility knife. When you're done, ensure that the new cord matches with the groove of the sash and that it's secured to the sash frame with a knot.

If the upvc sash still isn't moving, you can cut the cords using your side cutters. When the sash is completely free, you'll need to remove the access panel within the sash channel to expose the sash weight pockets, the counterweights, and the pulley system. If the window has been painted, you'll need to score the seams using either a hammer or chisel, to take off the panel without damaging it.

After you have removed the access panel there are two cast-iron sashweights inside each pocket. Take the one on the back and one on the front, and then tie each sash cord to a weight using a self-tightening knot. After tying the new cords, you'll need reconnect the sash weights and reset the pulley system to ensure it functions properly.

Drafts

Sash windows are a great option to add a touch of history to older homes. However they can be difficult to maintain. They are often difficult or impossible to close and open with a smooth, quiet operation. They can also be rattled by breeze, and allowing drafts in. These problems are usually caused by the swelling of wood or paint buildup, or sash cords that have rotted. There are a variety of easy and cost-effective methods to fix these problems and keep your sash window functioning effectively.

Disassembling an old sash is the first step in fixing it. Remove the sash, and frame, and make sure that all components are in good shape. Then, sand the wood to enhance its appearance and to prevent draughts. A small amount of wax or silicone spray can aid in allowing the sash to slide more easily. If the sash remains stuck, use an utility knife to cut off any paint layers. A new set of tilt pins can also improve the window's functionality.

Weights are pushed across pulleys in order to counterbalance the weight of the sash window. These weights are usually cast iron and are accessed from an access panel or pocket cover located inside the inner box lining of the window frame. To prevent the weights from crashing down, an dividing strip is hung within the frame to ensure they do not collide.

It isn't easy to reach these weights since the sash's upper part can be sealed with paint and then nailed into place. If you're patient and careful you can pull the sash out using a pair bar clamps that are spread apart. You may need to jiggle and tap to release it, but once it's out examine the sash and replace it with new rope.

While you're at the same time, you could also replace the sash balance to make the window easier to open and close. Replacing the balance of a double-hung window is a lot easier than it seems and you can do it yourself using the appropriate tools and a replacement kit.

Rotten sill

Even the best-maintained windows will eventually exhibit signs of rot. If the rot is limited to the sill, it could be possible to fix the window. If the rot has gotten into 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 rotten window sill before it causes further damage to the window. The first step is to eliminate the old sill plate and studs. You may need to install temporary support in the event that the studs bear weight. After taking the old sill off and washing off any paint remaining from the sill plate. After the sill has been cleaned then replace it with a brand new board and attach it to the studs.

A sill that is rotten can be unsightly and lead to future costly repairs. It can, for example cause the sash, that is hard to see to notice, to shift. This can result in cracks, bows or damaged glass pane. A rotten sill may also allow water to enter the wall, causing mold.

Replacing a damaged or rotting sill isn't as difficult as it might sound. It is essential to keep the window well-maintained to avoid rot, therefore you should regularly clean the window tracks and sashes to keep them clear of dirt and debris. Apply a protective seal on the frames of the windows to keep them dry. You can also apply a humidifier to control the humidity inside your home. This will stop wooden sashes from forming or swelling.

Sash windows are often afflicted by sashes that have become stuck. To fix them it is possible to apply small amounts of silicone spray or wax onto the window tracks to help them slide more easily. If the sashes have become stuck due to paint buildup you can use an utility knife to slice through the paint layers and free the sashes.

Another option to resolve a sticking sash is to reinstall the parting bead. If the sash is still sticking, you can also try draught-proofing it. This is done by placing a piece of rubber between the sash frame and sash. This will reduce airflow and improves acoustic qualities.
